Definitions
- This invention relates to! organic metal complexes and novel methods for the production of such complexes;
- Theialk'aline' earth-metal 2% organic complexes are produced in accordance with the present invention as a fluid, which is readily adapted for application where high concentrations of alkaline earth metal are desired, e. g. in lubricants.
- the complexalone can be produced in mineral oil solutions of at least about 20% concentrations; whereas if the complex is wanted in combination with other additives, it can be available in concentrations of at least about in mineral oils.
- Still another object of this invention is to provide novel methods of producing organic alkaline earth metal complexes.
- the'process of the present invention comprises combining a salt-forming material with an organic acid compound (to be understood hereinafter as the acid itself and/or an alkaline earth metal salt thereof) in the presence of a material which is referred to hereinafter as the promoter.
- an organic acid compound to be understood hereinafter as the acid itself and/or an alkaline earth metal salt thereof
- the promoter a material which is referred to hereinafter as the promoter.
- the precise function of the promoter material is not specifically understood since it has not been possible to specifically identify the molecular structure of the product produced.
- none of the complexes i. e., either those prepared by prior art techniques or those obtained under the present invention are susceptible of precise identification. This is clearly shown with respect to the prior art complexes by reason of the apparent disagreement among workers as to the nature of compounds which contribute metal in excess of the normal salt.
- the immediate product is produced by the use of a promoter, and at least one stage contains the promoter in chemical combination. It is possible, however, to recover the promoter from the product by suitable treatment as hereinafter explained, and the final product which then has a constitution difierent from the initial end product is, similar to the initial product, of utility as a lubricant additive.
- the present invention comprises the improvement in the process of pro-' ducing an alkaline earth metal complex of oil-: soluble organic acids, wherein an organic acid compound (to be understood hereinafter as the acid itself and/or an alkaline earth metal salt thereof) is caused to combine with a salt-forming metal compound under conditions whichwould produce a normal salt, which comprises increasing the amount of metal which will be thus combined by having present in the process mass.
- an organic acid compound to be understood hereinafter as the acid itself and/or an alkaline earth metal salt thereof
- An organic compound selected from the class consisting of those organic compounds which are water-soluble at a temperature of 50 C. to the extent of at least 0.0005% and which in the presence of water have an ionization constant greater than about 1X10- at about 25 0.; and the salts of such organic compounds; and
- a more specific aspect of the process comprising this invention may be defined as the process of producing an alkaline earth metal organic complex which comprises:
- An inorganic alkaline earth metal compound (1) which is water-soluble at a temperature of 50 C. of at least 0.0003% (2) In an amount such that there are present in the mass substantially more than 1 equivalent of alkaline earth metal, including the alkaline earth 'metalpresent in the remaining components, per equivalent of A plus B; and

- the salt complex contained the following properties:
- Example 6 The salt complex prepared in accordance with Example 5 was compared with a product which was made by a conventional technique, as shown in Example 6 below.
- EXAMPLE 6 1000 grams of the barium salt of mono-parafiln wax substituted naphthalene sulphonic acid given in Example 5 were heated to about 95 C. and barium oxide slurry (113 grams barium oxide and 100 grams water) was added to the mixture. The
- EXAMPLE 7 400'grams of the barium salt of mono-parafiin wax substituted naphthalene sulphonic acid disulphide containing 8.2% sulphate ash and 27 grams of para-tertiary-butyl phenol were placed in a suitable vessel and heated to 90 C. (ratio of equivalents is 1.54). A barium oxide slurry constituting 66.5 grams of barium oxide and 180 cc. of water was added to the mixture and refluxed for about one hour. The temperature was then slowly raised to about 160 C. over a period of about four hours and held at that level for'about 1.5 hours until substantially all of the water was removed. The salt complex was separated by filtering. The product was a viscous liquid, black in color, and contained a, very slight odor.' The following properties were determined for the salt complex:
- Example 7 The product obtained in accordance with Example 7 was then compared with a salt complex obtained under a conventional technique as shown in Example 8 below.
- EXAMPLE 8 20ml. of water were added to 450 grams of the barium salt of mono-parafiin wax substituted naphthalene sulphonic acid disulphide given in Example 7 and heated to a temperature of about C. 27.5 grams of barium oxide were then added to the mixture and the temperature was slowly raised to about 160-170 C. and held there for about one hour until substantially all of the water was removed. The salt complex was then separated by filtration. The product was fluid in consistency, black in color, and contained a slight odor. The following properties were determined for the product:
- the barium salt of monoparaflin wax substituted naphthalene sulphonic acid disulphide has a sulphate ash of about 8.2% and that the complex formed by the conventional technique did not increase the sulphate ash content appreciably.
- the method of the present invention produces a complex containing substantially more metal in combination.
- EXAMPLE 9 6000 grams of a 30% by weight oil solution of barium petroleum sulphonate (sulphate ash content 7.6%) were mixed with 348 grams of para-tertiary-butyl phenol in a 12-liter, 3-neck flask (ratio of equivalents 1.7) and heated to C. A slurry of barium oxide constituting 1,100 grams of barium oxide and 2,911 grams of water was then added and the mixture held there for about one hour at a temperature of about 90-95 C.

- the complexes of this invention can be also obtained by using a mixture of oil soluble organic acid and. the. alkaline earth metal salt thereof.
- the following example illustrates; this concept;
- the salt complexes formed with compounds containing barium metal possess exceptionally high metalratios as compared to those complexes which are obtained when usingother alkaline earth metal containing compounds. Consequently, in determining-the maximum amount of metal which can be incorporated intoa complex prepared by conventional techniques, the barium containing complexes were employed for such a purpose. Pursuant thereto, Examples 59 and 60 given below serve to show the highest amount of metalwhich can be incorporated into a salt complex' by conventional techniques. Furthermore, the oil-soluble petroleumsulphonic acids are exceptionally. better in producing high metal content salt complexes than other types of oil soluble organioacidcompounds.
- EXAMPLE 60 In this example the procedure employed in Example 59 was followed except that the dehydration step was conducted at a temperature of 200 C. for a period of one-half hour.
- the product obtained had th following properties:
- salt complexes obtained by conventional techniques will only have metal ratios as high as 2.25 or approximately 2.3.
- the process of the present invention will in every instance, wherein a substantial amount of excess inorganic alkaline earth metal compound is employed, and when using the same organic acid compound, produce products containing more metal than is possible by any of the prior art techniques.
- the salt complex produced by the process of this invention is treated with an acidic material and then distilled so as to remove substantially all of the ionizable organic compound, the remaining salt complex which constitutes essentially the promoter-free salt complex in combination with the acidic material, will have a higher ratio of total metal to metal in the normal salt of the organic acid than is possible with any prior art techniques.
- EXAMPLE 61 1530 grams of a 30% oil solution of barium petroleum sulphonate having a 7.6% sulphate ash, 88 grams of para-tertiary butyl phenol (ratio of equivalents is 1.7), 271 grams of BaO and 725 ml. of water were mixed together at 60- 70 C. The temperature of the mixture was raised to 100-105 C. and held there for one hour while 24 insuring thorough mixing. Thereafter the temperature was raised to ISO-160 C. and held at that level to remove substantially all the water. The complex was separated by filtration and had the following analysses:
- EXAMPLE 62 1530 grams of a 30% oil solution of barium petroleum sulphonate having a 7.6% sulphate ash were mixed with 725 ml. of water at about 60 C. Then 271 grams of BaO were added. The temperature of the mixture was raised to C. and held there for one hour while insuring thorough mixing. Thereafter the temperature was raised to -160 C. and held there for one hour to substantially remove all the water. The complex was separated by filtration and had the following properties.
- the first form of such complex is the immediate product with the promoter included therein in chemical combination.
- the second form of novel product is that which results from the treatment of the end product just described with an acidic material which has the effect, as stated above, of'liberating the promoter from the complex without any substantial change in the metal ratio of the complex.
- the liberation of the promoter by this step of treating the first-named complex with an acidic material may be followed by a recovery, as by distillation, of th promoter thus liberated, leaving the end product and complex substantially free of the promoter material.
- a third product which is probably different from each of the two named above may be produced by treating the complex initially formed with an acidic material prior to the removal by filtration of the excess inorganic alkaline earth metal compound.
- the promoter material is permitted to remain in the complex, and when this procedure is followed it has been found that unusually high metal ratios may be secured in the ultimate end product.
- the immediate end product formed by the use of the promoter material may be modified to recover therefrom a substantial portion of the promoter material used, by treating such immediate end product with a sufficient amount of an acidic material which in the presence of the mass will form a material having a higher ionization constant than the ionizable organic compound used as the promoter.
- the regenerated promoter may then be separated therefrom by any one of the several known means, or the regenerated promoter material may be left in the mass and the latter then treated with an additional amount of a salt-forming material, and it will be found that the concentration of the stably-held metal can'be further increased.
- the following are examples of such further steps in our process.
- Example 4 contained a sulphate ash of 23.8% where s t e same product after blowing with CO2 contained a sulphate ash of 232. Therefore, it can be seen that the metal ratio of the salt complex is substantially the same aftertreatment with CO2.

The product was fluid, dark red incolor, and contained no odor. The following properties were determined for the salt complex- COz product:
- the metal ratio of the product is substantially the same as the salt complex prior to being blown with CO2, since thesulphate ash content is substantially the same as before CO2 treatment.

- the distillate was then dissolved in isopropyl ether and then dried over magnesium sulpha-te, filtered and. then the magnesium sulphate was removed by filtration. 5 grams of residue remained. This residue was found to be phenol. thus indicating that treatment of the salt complex with an acidic material liberates at least a portion of the ionizable organic compound from complex formation.
- the percent sulphate ash of the COz-salt complex product indicates that little or no metal is removed from the complex as a result of the CO2 treatment and the distillation step to recover the ionizable organic compound.
- EXAMPLE 68 heated at a temperature of 200 C. under vacuum of 4; mm. to recover approximately 15 grams of phenol.

- the acidic material can be either a liquid, gas, or solid, prior to being incorporated in the mass which contains the salt complex.
- the acidic material usually employed is a liquid or a gas.
- the liquids. can include the strong or weak acids, such as, for example, hydrochloric, sulphuric, nitric, carbonic acids, etc., whereas the gas is for the most part an anhydride of an acid or an acid anhydride gas.
- the complex of the present invention can be produced. by using the same alkaline earth metal in the organic acid compound, promoter and inorganic compound; or such complexes can be derived from components containing dissimilar alkaline earth metals. In some instances it is desirable to employ a mixture of organic acid compounds which contain at least two or up to and including four dissimilar alkaline earth metals; or the same distribution of metals can be obtained by varying the type of promoter and/or inorganic compound in various combinations with the organic acid compound. It is therefore possible to employ various combinations of dissimilar alkaline earth metals in the starting materials used in preparing the complex product. 1
- the salt complex of the present invention is prepared by combining the aforementioned compounds in the presence of water.
- the water can be present as a result of addition thereof to the mixture, or liberated from either the essential components or other additionally present compounds as a result of being subjected to heat.
- the metal complex can be prepared when using small quantities of Water such as about 1 mole of water per mole of inorganic metal compound. However, more usually about 5 to 50, and preferably about 15 to 30, moles of water per mole of inorganic metal compounds are used.
- the complex formed with the inorganic alkaline earth metal compound, the oilsoluble organic acid or the alkaline earth metal salt thereof, and the promoter is prepared by heating the components in the presence of water at a superatmospheric temperature while insuring thorough mixing and then still further heating said mixture to substantially remove all of the water.
- At least five methods are available by which the complex can be formed, namely:
- the promoter is added to the oil-soluble normal salt of the organic acid, followed by addition of an aqueous solution or suspension of the inorganic alkaline earth metal compound thereto; the mixture is held at a superatmospheric temperature for a reasonable length of time while effecting thorough mixing, and then the total mixture is further heated to remove substantially all water which might be present;
- thestep of removing substantially all of the water which is present is accomplished at a temperature not substantially in excess of 350 C., preferably. about C. to 200 C.
- the techniqueemployed to remove the water includes, for example, a conventional flash stripping operation which involves passing the material in a thin film state over a large heated area of glass, ceramic, or metal; heating under sub-atmospheric pressure as well as heating under either atmospheric or superatmospheric pressure.
- the acidic material when used in gaseous form may be used to remove thelast portion of water. It can therefore be seen that the temperature as well as the time for effecting substantial removal of water will vary considerably depending on the amount of material being processed and on the technique employed therefor.
- the time required to effect substantial removal of water is at least about 15 minutes or less and can be as high as 1045 hours or more.
- the components are combined and agitated at an elevated temperature to insure thorough mixing, and then water is removed therefrom. It should be understood that the process to form the complex can be effected without the preliminary heating and mixing period, if desired. ,It is therefore not essential to this invention to have such a preliminary step because all that appears necessary is to mix the components and remove substantially any water which is present.

This invention relates to! organic metal complexes and novel methods for the production of such complexes;
It is now well known that when-preparinga salt or soap of an organicacid, the mere-use of an excess of neutralizing agent, which-inthe, prior art has been in theiorinof theoxide, hydroxide, carbonate, etc. of the desired-metal, may result in a product which contains anamount of metal in excess of that theoretically required to replace the acidic hydrogens of the organic acid used as the starting material. 7 I
Workwith this type of product has shown that for many uses, particularly'whereextreme care must be exercised to prevent the composition from beingcorrosive, as-ior example inlubricants, desirable results are secured fiby the useof these so-called basic salts or soaps.-
Among the earlier workersin the art who recognized this factor andindicated that the use of basic soaps was desirable -=Was Bergstrom who, in hisPatents Nose-2270p and 2,27 9,086, made reference to the desirability of "using the basic soap without, however, givingan-y specific method for the preparation of such soaps. A similar disclosure is found'in Van EssP-atent No. 2,372,411.
With the demonstrated.- superiority of such basic soaps overthe normal or slightly acidic soaps, the prior art workers then attempted to find Ways ofincreasingthe basioity of the soaps, or stated in another way,- increasing the amount of metal, for-example; heldin stable form in What was termed asa metal com-plex.- One of the earliestgpatents referring to these basic salts ascomplexes or coordination compounds is -McNab No. 2,418,894, who gives noindicationin his patent as to the molecular structure of the product. As might be expected, one 'of the first steps employed to produce ametalsalt having an intended large excess of metaLin-combination-was to'use an unusually largeexcessof neutralizingagent, such as lime. Arepresentative patent disclosing this procedure isGriesinger et al. No; 2,402,325 who su gested the use of neutralizin agent up to 220% of the theoretical amount, This large excess of neutralizing agent was employed in a process moreor lessconventional for producing salts or soaps exceptinglthat-the process was-carried out in the presence oi st ean'i in order to facilitate the formation of-the product;
The Work of Griesinger was followed by the work of Campbell and Dellinger' as g'iveninPatentNo. 2,485,861 These patenteesba'se their-"disclosure on the hypothesis that minor amounts of an alkaline earth man hydroxide or carbonate can be p'eptized, orh n'astatebf colloidal suspension in oil by means off'anoi1-solub1e"'mahog any sulphonate. Another worker in the art who sought to combine in such complexes ariexc'ess amount of metal wasMertes whose" Patent No. 2,501,731 Wasgranted' Mai lf-2BL1950'J M ertes first prepared the normal-soap aiidstated that such soap-or soap comes at any haveadditional base combined ther byj'a' more or less simple mixing and heati tiori'followed by filtering. Th'edisclosure in Mertes appears to indicate that his roduct 'issimilar to" that of Campbell and Dellinger, in that the e'x'cess neutralizi'ng agent was held in the product in'the form ofaco'll'oidal suspension.
All of the previously enumerated processeshave been tried, notonlyduplicating ce'rtainof the examples given in the above-identified pa'tents, but
also using diifer'ent acids andfdifierent neutralizing' agents? As a result of f theseexperiinents; it has been'foun'd" that there isadefinite upper limit to the amount'of alkaline earth' metal which can be held in combination or in colloidalsuspension byrn'ean's of th'es'ejprior'artprocessesfi The greatest total amount of alkaline earth metal which can' 'possiblybe thus incorporated in the product by" means of any Of thse" prior art processes has been obtained when usingbarium-and in that case it is equalto about 2.3 timestheftheoretical .a'mou'nt present in thenormal salt." For thepurpose of the present inventionthe'ratio'of the'total metal iIlWhiGdlIliilGX to the amount of metal which is in the form of the normal salt of theoil soluble organic 'acid" will hereinafter 'be' "referred to as the metal ratio? By meansof'the present invention, it is now possible to 'obtain' alkaline earth mtal organic complexes which" contain "more" metal or higher metal .rati'os than" is possible by 'prior art processes'. With-regard tdlubridint's, these-Thigh metal containingcornplexes ari'fsr'iexsmpieparticularly suited-as'detrgents, and by'reasqn' of the metal concentrationcasts used "in amounts appreciably less" than other additives known in the prior art in order to attain a desired level of performance." t will a1s o"b"obseryed"that by virtue of the ef fectiv natur'epf'thefprs'snt complexes lubricants, usually 'itfw'illcost'less to obtain a desired result,; becausefappreciahly l-'ss additive is required. Theialk'aline' earth-metal 2% organic complexes are produced in accordance with the present invention as a fluid, which is readily adapted for application where high concentrations of alkaline earth metal are desired, e. g. in lubricants. For example, if the complexalone is desired, it can be produced in mineral oil solutions of at least about 20% concentrations; whereas if the complex is wanted in combination with other additives, it can be available in concentrations of at least about in mineral oils.
It is a principal object of our invention to provide an alkaline earth metal organic complex which contains in stable form an amount of metal substantially greater than that contained in any of the so-called alkaline earth metal complexes previously produced. It has been found that a metal ratio substantially greater than that possible with the prior art processes give results which are strikingly superior, especially in the field of lubricants in which these products have particular utility.
. It is a further object of this invention to produce by our improved process, complexes which, while containing the same amount of alkaline earth metal as in complexes produced by the prior art process above described, are nevertheless different from and superior to such prior art complexes.
Still another object of this invention is to provide novel methods of producing organic alkaline earth metal complexes.
Further objects of our invention will appear as the description proceeds.
Tothe accomplishment of the foregoing and related ends, said invention then comprises the features hereinafter fully described and particularly pointed out in the claims, the following description setting forth in detail certain illustrative embodiments of the invention, these being indicative, however, of but a few of the various ways in which the princip le of the invention may be employed.
In its broadest aspects, the'process of the present invention comprises combining a salt-forming material with an organic acid compound (to be understood hereinafter as the acid itself and/or an alkaline earth metal salt thereof) in the presence of a material which is referred to hereinafter as the promoter. The precise function of the promoter material is not specifically understood since it has not been possible to specifically identify the molecular structure of the product produced. At present, it appears that none of the complexes, i. e., either those prepared by prior art techniques or those obtained under the present invention are susceptible of precise identification. This is clearly shown with respect to the prior art complexes by reason of the apparent disagreement among workers as to the nature of compounds which contribute metal in excess of the normal salt. In one instance, it is held that this phenomenon is a result of partial replacement of the hydroxyl groups in the inorganic metal compound, whereas among another group of prior art workers it is held that the high metal containing complexes are actually colloidal suspensions or dispersions in which the salt of the organic acid is the peptizing agent. In the present invention, the immediate product is produced by the use of a promoter, and at least one stage contains the promoter in chemical combination. It is possible, however, to recover the promoter from the product by suitable treatment as hereinafter explained, and the final product which then has a constitution difierent from the initial end product is, similar to the initial product, of utility as a lubricant additive.
Stated more particularly, the present invention comprises the improvement in the process of pro-' ducing an alkaline earth metal complex of oil-: soluble organic acids, wherein an organic acid compound (to be understood hereinafter as the acid itself and/or an alkaline earth metal salt thereof) is caused to combine with a salt-forming metal compound under conditions whichwould produce a normal salt, which comprises increasing the amount of metal which will be thus combined by having present in the process mass.

(0) Water, including free and combined water in the other components;
and maintaining the mass at a temperature and for a period of time sufficient to drive off substantially all free water and Water of hydration which may be present. 1
A more specific aspect of the process comprising this invention may be defined as the process of producing an alkaline earth metal organic complex which comprises:
I. Preparing and mixing a mass in which, at 50 C., at least 50% of the components are in the liquid state and which mass the active components consist of:
A. An oil soluble organic acid compound;

at least about 0.0005%; and
(c) In saturated aqueous solutions at about 25 C. a pH of not greater than about 7;

The salt complexes formed with compounds containing barium metal possess exceptionally high metalratios as compared to those complexes which are obtained when usingother alkaline earth metal containing compounds. Consequently, in determining-the maximum amount of metal which can be incorporated intoa complex prepared by conventional techniques, the barium containing complexes were employed for such a purpose. Pursuant thereto, Examples 59 and 60 given below serve to show the highest amount of metalwhich can be incorporated into a salt complex' by conventional techniques. Furthermore, the oil-soluble petroleumsulphonic acids are exceptionally. better in producing high metal content salt complexes than other types of oil soluble organioacidcompounds.

23' EXAMPLE 59 2500 grams of a 30% oil solution of barium petroleum sulphonate containing 7.6% sulphate ash were heated to 95 C. and a slurry of barium oxide containing 386 grams of barium oxide and 1215 grams of water was added thereto. The mixture was stirred for one hour at a temperature of 100 C. and then heated slowly over a period of three hours to a temperature of 150 C. This temperature was maintained for about one hour until substantially all the water was removed. The salt complex thus produced had the following properties:

Basic No. 29.0 Per cent sulphate ash 15.3 Metal ratio 2.16
From the above Examples 59 and 60 it can be seen that salt complexes obtained by conventional techniques will only have metal ratios as high as 2.25 or approximately 2.3. By comparison, the process of the present invention will in every instance, wherein a substantial amount of excess inorganic alkaline earth metal compound is employed, and when using the same organic acid compound, produce products containing more metal than is possible by any of the prior art techniques. Furthermore, in every instance where the salt complex produced by the process of this invention is treated with an acidic material and then distilled so as to remove substantially all of the ionizable organic compound, the remaining salt complex which constitutes essentially the promoter-free salt complex in combination with the acidic material, will have a higher ratio of total metal to metal in the normal salt of the organic acid than is possible with any prior art techniques. By Examples 63-74 inclusive given hereinafter, it will be shown that the treatment of the salt complex produced by the process of the present invention with an acidic material does not significantly affect the Furthermore, it is shown in those examples that the distillation of the thus acidic material treated complex so as to recover the ionizable organic compound does not significantly affect the metal ratio of the complex.
In another pair of experiments, a comparison was made between the process of the present invention and a conventional process, when using duplicate amounts of components. It is clearly evident from the following examples that this invention will give substantially better results with respect to metal concentration of the complex than is obtainable by the conventional technique.
EXAMPLE 61 1530 grams of a 30% oil solution of barium petroleum sulphonate having a 7.6% sulphate ash, 88 grams of para-tertiary butyl phenol (ratio of equivalents is 1.7), 271 grams of BaO and 725 ml. of water were mixed together at 60- 70 C. The temperature of the mixture was raised to 100-105 C. and held there for one hour while 24 insuring thorough mixing. Thereafter the temperature was raised to ISO-160 C. and held at that level to remove substantially all the water. The complex was separated by filtration and had the following analysses:

The temperature of the mixture was raised to C. and held there for one hour while insuring thorough mixing. Thereafter the temperature was raised to -160 C. and held there for one hour to substantially remove all the water. The complex was separated by filtration and had the following properties.
Basic No. 36.0 Per Cent sulphate ash 15.34 Metal ratio 2.14
From the foregoing it will be noted that by following the process of the present invention, two types of metal complexes may be produced, both of which are difierent from any produced by any of the prior art processes. The first form of such complex is the immediate product with the promoter included therein in chemical combination. The second form of novel product is that which results from the treatment of the end product just described with an acidic material which has the effect, as stated above, of'liberating the promoter from the complex without any substantial change in the metal ratio of the complex. The liberation of the promoter by this step of treating the first-named complex with an acidic material may be followed by a recovery, as by distillation, of th promoter thus liberated, leaving the end product and complex substantially free of the promoter material. A third product which is probably different from each of the two named above may be produced by treating the complex initially formed with an acidic material prior to the removal by filtration of the excess inorganic alkaline earth metal compound. When following this latter procedure, the promoter material is permitted to remain in the complex, and when this procedure is followed it has been found that unusually high metal ratios may be secured in the ultimate end product.
As previously indicated, the immediate end product formed by the use of the promoter material may be modified to recover therefrom a substantial portion of the promoter material used, by treating such immediate end product with a sufficient amount of an acidic material which in the presence of the mass will form a material having a higher ionization constant than the ionizable organic compound used as the promoter. After a portion of the promoter material has been thus regenerated by treating the immediate product with an acidic material, the regenerated promoter may then be separated therefrom by any one of the several known means, or the regenerated promoter material may be left in the mass and the latter then treated with an additional amount of a salt-forming material, and it will be found that the concentration of the stably-held metal can'be further increased. The following are examples of such further steps in our process.

By comparison, the product of Example 4 contained a sulphate ash of 23.8% where s t e same product after blowing with CO2 contained a sulphate ash of 232. Therefore, it can be seen that the metal ratio of the salt complex is substantially the same aftertreatment with CO2.
. EXAMPLE 64 1 6043 grams of the salt complex prepared in accordance with Example 9 were placed in a suitable vessel and CO2 gas was injected at the bottom oi the vessel at a rate of 3750 cc.per minute for a period of 1%; hours. During this period, the temperature was in the range of 30-70 C. Atthe-end of the blowing operation the product weighed 6346 grams, showing a gain in weight of 311 grams. The product was fluid, dark red incolor, and contained no odor. The following properties were determined for the salt complex- COz product:
Basic No. 4.3 Percent sulphate ash 22.7
Itcan be seen, therefore, by the gain in weight of the product that the CO2 actually enters into combination with the salt complex. Furthermore, the metal ratio of the product is substantially the same as the salt complex prior to being blown with CO2, since thesulphate ash content is substantially the same as before CO2 treatment.
1288 grams of the salt complex prepared in accordance with the method of Example. 5 was blown with CO2 at a temperature of 3050 C. until the product showed an acid reaction. Following this CO2 treatment, the product was blown with nitrogen for a period of minutes. The product thus produced was very viscous, reddish brown in color, and did not contain any odor.

The temperature was then slowly raised over a period of three hours to C. and maintained at that level for an additional period of one hour until substantially all'the water was removed.

The COz-Salt complex product was then heated at a temperature of C. under a vacuum of 10 mm. producing a distillate weighing about 10 grams. The distillate was then dissolved in isopropyl ether and then dried over magnesium sulpha-te, filtered and. then the magnesium sulphate was removed by filtration. 5 grams of residue remained. This residue was found to be phenol. thus indicating that treatment of the salt complex with an acidic material liberates at least a portion of the ionizable organic compound from complex formation.
After the distillation step, the following properties for the salt complex were determined:
Basic No 2.96 Percent sulphate ash 22.4
The percent sulphate ash of the COz-salt complex product indicates that little or no metal is removed from the complex as a result of the CO2 treatment and the distillation step to recover the ionizable organic compound.

Component A--The oil soluble organic compounds used as starting materials The organic acid compound used as one of the starting materials in our process may be the oil soluble organic acid themselves and/or an alkaline earth metal salt thereof. At this point it should be noted that whereas Mertes found it necessary to first prepare a normal metal salt and then react such normal salt with an additional amount of a salt-forming material, our process can be carried on as a one-step process by beginning with the oil-soluble organic acid. While it is possible to first prepare the normal metal salt of the organic acid in the usual way, by a conventional salt-forming procedure, and then begin our process by utilizing such normal metal salt as one of the starting materials, it may b more convenient to employ as the starting material the organic acid rather than the salt thereof. Our process is operable for the production of certain types of compounds when utilizing as starting materials any of the products produced by the prior art processes. Also, as a starting material, mixtures of acids and salts can be used to produce the complex. The variety of classes of organic acids which can be employed are, for example, sulphur acids, carboxylic acids, phosphorus acids, etc. of the aliphatic and cyclic types, and the corresponding thio-acids.
More specific examples of organic acids are the sulphur acids including sulphonic, sulphamic, sulphinic, thiosulphonic, etc., and of these the sulphonic acids will find particular application under the present invention. A more specific identification of the sulphonic acids is given hereinbelow.
The carboxylic acids-include the fatty acids whereinthere arepresent at least about 12 carbon atoms, such as, for example, palmitic, stearic, myristic, oleic, linoleic, etc. acids. The carboxylic acids of the aliphatic type can contain elements in the aliphatic radical other than carbon and hydrogen; examples of such acids are the carbamicacids, ricinoleic acids, chlorostearic acids, nitro-lauric acids, etc. In addition to the allphatic carboxylic acids, it is intended to employ the cyclic types such as those containing a benzenold structure, i. e., benzene naphthalene, etc., and an oil-solubilizing radical or radicals having a total of at least about 15 to 18 carbon atoms. Such acids are the oil-soluble aliphatic substituted aromatic acids as for example, stearylbenzoic acids, monoor polywax substituted benzoic or naphthoic acids wherein the wax group containsat least about 18 carbon atoms, cetyl hydroxy-benzoic acids, etc. The cyclic type of carboxylic acids also includes those acids which have'present in the .compound a cycloaliphatic group. Examples of such acids are petroleum naphthenic acids, cetyl cyclohexane carboxylic acids, di-lauryl deca-hydronaphthalene carboxylic acids, di-octyl cyclopentane carboxylic acids, etc." Itls also contemplated to employ the thiocarboxylic acids, that is, those carboxylic acids in which one or both of the oxygen atoms of the carboyxlic group are replaced by sulphur. These carboxylic and thic-carboxylic acids can be represented by the following formulae:
wherein R is an aliphatic radical, a: is at least 1, and (R'M contains a total of at least about 15 to 18 carbon atoms; T is a cyclic nucleus such as benzene, naphthalene, diphenyl ether, diphenylene oxide, diphenyl sulphide, diphenylene sulphide, phenol, hydroxy-naphthalenes, phenol disulphides, petroleum naphthenes, cyclohexane, cyclopentane, chloro-cyclohexane, nitro-cyclopentane, deca-hydronaphthalene, mercaptodeca-hydro-naphthalene, etc.; and X is either oxygen or sulphur. In Formula II, R is an aliphatic group containing at least 12 carbon atoms and X is either oxygen or sulphur. R, R, and T can also contain other substituent groups such I as 'nitro, amino, hydroxy, mercapto, halogen etc.
Representative examples are nitro-stearic acids,
ceryl-chloro salicylic acids, chloro-palmitic acids, cetyl anthranilic acids, stearyl mercaptonaphthoicacids, etc. a
The phosphorus acids include triand pentavalent organic phosphorus acids and the correspending thio-acids, which are, for example, phosphorus, phosphoric, thiophosphoric, thiophosphorous, phosphinic, phosphonic, thlophosphinic,.thiophosphonic, etc. acids. Among the most useful of the phosphorus acids are those represented by the following formulae:
an organic radical and at least one B ishyidrogen. Therefore, such formulae include the-.oil-f soluble organic thio-acids of phosphorus, more particularly the organic thiophosphorlc acids and the organic thiophosphorous' acids. .The organic radicals R and R. can be aliphatic, cycloaliphatic, aromatic, aliphatic--v and. cycloaliphatic-substituted aromatic, etc. The organic radicals R and R preferably contain a total of at least about 12 carbon atoms in each of the above thio-acid types I and II. Examples.v of such acids are dicapryl dithiophosphoric acids; di-(methyl-cyclohexyD- dithiophosphoric acids, dilauryl dithiophosphoric acids, dicapryl dithiophosphorous acids, di-(methyl-cyclohexyl) die thiophosphorous acids lauryl mon9thiophosphoric acids, di-(butyl-phenyl) dithiophosphoric acids, and mixtures of two or moreoi the forcev going acids.
Certain of the above'described'thio acids oi phosphorus such as for example di-capryl di-v thiophosphoric acid are also commonly referred to as acid esters. I
As indicated, our process is applicable not only when using the oil-soluble organicacid as such as one of the starting materials, but also the al: kaline earth metal salts of such organicacids. The present process will produce a high metal content organo metallic material when as one of the starting materials-one uses any of the metal organic complexes produced bythe prior art workers, such as for example, Bergstrom, Griesinger, Campbell et al., and Mertes. We thus may utilize as a starting material theend I product produced by these prior art workers and from them produce the novel high metal content complex of our invention. 7 r

The- 'aeidic-material" i ls-previouslyindicatedIone form'of the process of the pr'esentlinvention includes the step of treating: the immediate complex" product with an acidic materialT for the purpose of" liberating therefrom at least a portion of the materia1 pre viously refer-redlto as the promoter. A particularly effective acidic material which has been utilized for this purpose is carbon di-oxide. We are aware of thefactthatMertes in his aboveidentified Patent No. 2,501,731 suggested transforming aisodium hydroxide=calcium sulphonate complex" into "the sodii m 'ca'rbona te-calcium' sulphonate complexcr" the corresponding bicarbonate complex by blowingthe hydroxide complex with carbon dioxide at elevated temperatures:

The acidic material usually employed is a liquid or a gas. The liquids. can include the strong or weak acids, such as, for example, hydrochloric, sulphuric, nitric, carbonic acids, etc., whereas the gas is for the most part an anhydride of an acid or an acid anhydride gas.
The following are additional specific examples of acidic materials, viz.: HCl, S02, S03, CO2, air
of the present invention, but that under certain conditions, some are more effective or desirable than others. a
The complex of the present invention can be produced. by using the same alkaline earth metal in the organic acid compound, promoter and inorganic compound; or such complexes can be derived from components containing dissimilar alkaline earth metals. In some instances it is desirable to employ a mixture of organic acid compounds which contain at least two or up to and including four dissimilar alkaline earth metals; or the same distribution of metals can be obtained by varying the type of promoter and/or inorganic compound in various combinations with the organic acid compound. It is therefore possible to employ various combinations of dissimilar alkaline earth metals in the starting materials used in preparing the complex product. 1
Process conditions The salt complex of the present invention is prepared by combining the aforementioned compounds in the presence of water. The water can be present as a result of addition thereof to the mixture, or liberated from either the essential components or other additionally present compounds as a result of being subjected to heat. However, it is preferred to add water to the'mixture to effect salt complex formation. It has been found that the metal complex can be prepared when using small quantities of Water such as about 1 mole of water per mole of inorganic metal compound. However, more usually about 5 to 50, and preferably about 15 to 30, moles of water per mole of inorganic metal compounds are used.
Generally the complex formed with the inorganic alkaline earth metal compound, the oilsoluble organic acid or the alkaline earth metal salt thereof, and the promoter is prepared by heating the components in the presence of water at a superatmospheric temperature while insuring thorough mixing and then still further heating said mixture to substantially remove all of the water. At least five methods are available by which the complex can be formed, namely:
(a) The promoter is added to the oil-soluble normal salt of the organic acid, followed by addition of an aqueous solution or suspension of the inorganic alkaline earth metal compound thereto; the mixture is held at a superatmospheric temperature for a reasonable length of time while effecting thorough mixing, and then the total mixture is further heated to remove substantially all water which might be present;
(b) The inorganic alkaline earth metal comv36 pound in a drystate is added to a mixture of organic acid or a normal salt of such organic acid, promoter-and water heating while insuring thorough mixing, and then further heating to remove substantially all of the water;
(c) The acid of the desired salt of organic acid is mixed with thepromoter, then an aqueous solution or suspension of the inorganic alkaline earth metal compound is added thereto, the mixture is heated and agitated at a superatmospheric temperature for a time sufficient to insure thorough mixing, and followed by subjecting the total mixture to dehydration conditions in order to remove substantially all of the water;
((1) In any of the methods discussed herein for preparing the salt complex, a substantial increase in metal content is usually effected by treating the mass containing the complex product with an acidic material just after substantial amounts of water are driven off and just before the mass is filtered.
(e) The sediment formed from any of the aforementioned methods can be employed either alone or with additional promoter in any of the three methods given above.
In all of the methods described above for preparing the salt complex, thestep of removing substantially all of the water which is present is accomplished at a temperature not substantially in excess of 350 C., preferably. about C. to 200 C. The techniqueemployed to remove the water includes, for example, a conventional flash stripping operation which involves passing the material in a thin film state over a large heated area of glass, ceramic, or metal; heating under sub-atmospheric pressure as well as heating under either atmospheric or superatmospheric pressure. At a later stage, the acidic material when used in gaseous form, may be used to remove thelast portion of water. It can therefore be seen that the temperature as well as the time for effecting substantial removal of water will vary considerably depending on the amount of material being processed and on the technique employed therefor. Generally, the time required to effect substantial removal of water is at least about 15 minutes or less and can be as high as 1045 hours or more. Usually, however, it is most convenient to employ atmospheric pressure for such an operation, and consequently it requires about 1 to 5 hours to remove substantially all of the water from the process mixture. It was observed that satisfactory complexes are obtained when using any of the techniques described above, and that the final water content can be up to about 2% or more.
Usually, as indicated above, the components are combined and agitated at an elevated temperature to insure thorough mixing, and then water is removed therefrom. It should be understood that the process to form the complex can be effected without the preliminary heating and mixing period, if desired. ,It is therefore not essential to this invention to have such a preliminary step because all that appears necessary is to mix the components and remove substantially any water which is present.
For the purposes ofthisv specification and the appended claims, the relativeamounts of oilsoluble organic acid or the alkaline earth metal salt thereof and promoter is expressed in the ratio of equivalents of the former to the latter. In accordance therewith, the ratio of equivalents of Oil-soluble organic acid or the alkaline earth metal salt thereof to promoter is from about 1 material employed isfpref b me -1i 3.7 to IOto about o' tq-l nmreallyirdm about 11' to .lito about ,l'to 1', andprererably from, about 3to 2to about? to2. p j M H The amount of inorganic alkaline earth metal compound employed generally will be sufilcient tohave present ,in the total mass at least more than about one equivalent of alkaline earth metal, regardless" of" how combined, per equivalentof oil-soluble organic acid or the alkaline earth metal salt'thereof plus-promoter In other words, the amount of inorganic alkaline'earth metal compound employed must be such that there is more than: the theoretical amount required-to form merely a normalsalt of oilsoliible. or.- ganic acid and the pro ote 7 poses of this specification and the appended claims, the amount of inorganic alkaline earth metal compound employed will be: expressedas an amount such that there ar'e pres'em -m the mass more than one equivalent 'oflalkaline earth metal, including the alkaline. earth, metafwhich is present in the form of the'salt o'fthe oilsoluble organic acid and the promoter, per equivalent of oil-soluble organic acid; and; alkaline earth metal salt thereof plus the promoter:

In accordancetherewith; the salt complex as of this invention will-have metal 38 ratiosgreater than land up to lo'orinore; pref erably from about 2 to 8. As for the finished salt complex which is treated with an acidic material, the metalcontent issubstantially. the same as in the complex prior to treating. Consequently the same metal ratios as given above will apply to such treated product. In those instances where the finished salt complex is treated with an acidic material and the ionizable organic compound is removed from the resultant product by distillation, or otherwise it is found that the metal ratios will be substantially the same as in the salt complex before treating with the acidic material.
By. reason of the high metal ratio of the complexes produced in accordance with this invention; the following theories are suggested as a po's's'ibleexplanation or how the meta1:is.:com:- bined It is t'o be understood,- however, that such theories are advanced for the purpose. of offering explanations; and are not. to be cone strued as limitations on the scope of the present invention.
In the following; equations, represents a promoterin which H isanionizable hydrogen and M represents a divalent metal. Assuming that the promoter may act as a catalyzer for the formation of inorganic polymeric configurations, viz. (MO)H, which are bonded to the acid group (e. g;, the sulphonate radical in the preferred instance), the possible reactions that may occur with the sulphonate radical are:

The resultantlcomplex, according to the above theory, can be a. complex mixture ota-ll' the potential products listed above. It is. apparent that high. metal ratios are. possible under. this theory: Another theory isbased upon an electronic in terpretation. For exarnple in. the casesof the neutral sulphonate, the charges. are distributed as follows::

and structure (1)) would have a metal ratio of' 5.0. Combinations of neutral sulphonate and one or both structures would explain the whole number and fractions of metal ratios which are obtained in actual practice.
After the structures (a) and (b) are formed, if hydroxyl ions are present in the reaction mass the following reactions may take place:
The AX- ions may then react with M(OH) 2 to produce AXMOH, and the latter would in turn lead to the formation of additional amounts of structures (a) and b). The cycle may occur repeatedly.
According to this electronic explanation, the AX- residue of the basic promoter salt AXMOH appears to function as a carrier for the M(OI-I) 2, and thus facilitating the communicating of the M(OH)2 into close positions with the negatively charged oxygen atoms of the sulphonate radical.
Having thus described the present invention by furnishing specific examples thereof, it is to be understood that no undue limitations or restrictions are to be imposed by reason thereof, but that the scope of this invention is defined by the appended claims.
The salt complexes produced in accordance with the present invention can be employed in lubricants including oils and. greases, and for such purposes as in crankcases, transmission gears, etc. as well as in torque converter oils. Other suitable uses for such complexes are in asphalt emulsions, insecticidal compositions, fire-proofing and stabilizing agents in plasticizers and plastics, paint driers, rust inhibiting compositions, pesticides, foaming compositions, cutting oils, metal-drawing compositions, flushing oils, textile treatment compositions, tanning assistants, metal cleaning compositions, emulsifying agents, antiseptic cleansing compositions, penetrating agents, gum solvent compositions, fat splitting agents, bonding agent for ceramics and asbestos, asphalt improvin agents, flotation agents, improving agents for hydrocarbon fuels such as e. g., gasolene and fuel oil, etc.
