Definitions
- This invention relates to organic metal complexes and novel methods for the production of such complexes.
- the alkaline earth metal 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 complex alone it can be produced in mineral oil solutions of at least about 20% concentrations; whereas if the complex is wantedin 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 different 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 producing 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 saltforming metal compound under conditions which 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 l 10 at about 25 C.; 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 organic compound AH in which H is hydrogen and A is an organic anionic radical having:
- inorganic alkaline 'earth'metal comia'ound v (1) which is water-soluble at a temperature of 50 C. of at least0.0003% (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 metal present in the remaining components'per equivalent of A plus B;
- Thefollowing examples give the preparation of a plurality of products which range in metal content from about that of the normal salt up to many times that amount.
- the salt complex is a viscous liquid, light brown in color and having a very slight odor.
- the salt complex had the following properties:
- Example 2 500 grams of the barium salt of the petrolatum sulphonic acid given in Example 1 were mixed with a slurry of barium oxide (containing 38- grams of barium oxide and 50 grams of water) and placed in a 2-liter, 3-neck flask, heated at about 160 C. for one hour until substantial ly all of the water was removed, and then the product was filtered.
- the resultant basic sulphonate has the following properties:
- EXAMPLE 3 1009 grams of the barium .salt of unsaturated paraffin wax sulphonic acid containing 13.1% sulphate ash were mixed with 455 grams of a mineral oil having a viscosity of 160 SSU at 100 F. and 109.5 grams of para-tertiary-butyl phenol (ratio of equivalents is 1.54), placed in a suitable vessel and heated to about C.
- the salt complex thus prepared had the following properties:
- the salt complex product was fluid, brown in color, and did not contain any odor.
- Example 3 The preparation given in Example 3 is a typical illustration of the present invention.
- Example 4 a basic sulphonate was prepared in accordance with a conventional technique for comparison with the product given in Example 3.
- EXAMPLE 4 511 grams of the barium salt of unsaturated parafiin wax sulphonic acid given in Example 3 were mixed with '75 grams of water and heated to about 60 C. with stirring. 58 grams of barium oxide were added to the mixture, which was then heated to about 150 C. and held there for one hour until substantially all of the water was removed. The product was filtered with the aid of Hyfio in order to separate the complex salt.
- the salt complex had the following properties:
- the salt was a waxy solid, brown in color, and did not contain any odor.
- 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-paraffin 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 total mixture was held at a temperature of 100 C. for about one hour, and then dehydrated at a temperature of about 150 C. for about one hour. The salt complex was separated by filtration. Throughout the above preparation a nitrogen atmosphere was maintained above the mixture. The resultant salt complex was liquid and black in color. The following properties were determined for the product:
- EXAMPLE 7 400 grams of the barium salt of mono-parraifin 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.
- 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 20 ml. 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 60 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 salt complexes formed with compounds containing barium metal possess exceptionally high metal ratios as compared to those complexes which are obtained when using other alkaline earth metal containing compounds.

Thereafter the temperature was raised to l50-160 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 the promoter thus liberated, leaving the end product and complex substantially free of the promoter material.
- a third product which is probably difierent 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 promotermaterial 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 enizab e or n com un eed s he om te Aiter a portion or th romoter mate ial.

- the; step of treating withan acidic material" such as carbon dioxide or air has the eiiect. of freeingfrom the immediate comp x P duct formed at leas a n the promoter used. hus the presence inthe immediate complex product ofthe promoter material, in combined form, clearly distinguishes the immediate complex product from any metal organic complex type material heretofore produced. Moreover, the nature of the product formed by regenerating from the immediate end product at least a portion of the promoter material leaves that complex with a composition which is quite different from the other prior art metal organic complexes previously produced. It is recognized that in accordance with the present invention, the alkaline earth metal salt of the ionizable organic compound can be employed as the promoter in forming the salt complex. However, when such a salt is used as the promoter and the resulting complex is treated with an acidic material, the metal-free ionizable organic compound is freed from its salt.
- an important feature or characteristic of the acidic material is that it must, when present in the mass containing the complex, possess an ionization constant higher than the ionizable organic compound used as the promoter.
- 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 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.
- 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 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 waterwhich might be present;
- the inorganic alkaline earth metal compound in a dry state 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;
- the acid of the desired salt of organic acid is mixed with the promoter, 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;
- a substantial in-. crease 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.
- the step of removing substantially all of the water which is present is accomplished at a temperature not substantially in excess of 350 0., preferably about C. to 200 C.
- the technique employed to remove the water includes, for example, a conventional fiash 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 the last portion of water.
- 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 Generally, the time required to effect substantial removal of water is at least about 15 minutes or less and can be as high as 10-15 hours or more.

Mastin, and Alan Rhodes, Cleveland, Ohio, assigno'rs to The Lubrizol Corporation, Wickliffe, Ohio, at corporation of Ohio No Drawing, Original application m n 16,
1951, SerialsNo. '216,103. Divided and this application December 28, 1951, Serial No. 263,961
No 279,258, filed March 23, 1952.
This invention relates to organic metal complexes and novel methods for the production of such complexes.
It is now well known that when preparing a salt or soap of an organic acid, the mereuse of an excess of neutralizing agent, which in the prior art has beenv in the form of the-oxide, hydroxide, carbonate, etc. of the desired metal, may result in a product which contains an amount of metal in excess of that theoretically required to replace the acidic hydrogens of the organic acid used as the starting'materialr Work with this type of product has shown that for many uses, particularly where extreme care must be exercised to prevent the composition from being corrosive, as for example in lubricants, desirable results are secured by the use of these so-called basic salts or soaps.
Among the earlier workers in the art who rec.- ognized this factor and indicated that the use of basic soaps was desirable was Bergstrom who,
in his Patents Nos. 2,270,577 and 2,279,086, made reference to the desirability of using the basic soap without, however, giving any specific method for the preparation of such soaps. 'A similar disclosure is foundin Van Ess- Patent No. 2,372,411.
With the demonstrated superiority of such basic soaps over the normal or slightly acidic soa s, the prior art workers then attempted to find ways of increasing the b'asicity of the soaps, or stated in another way, increasing the amount of metal, for example, held in stable form in what was termed as a metal complex. One of the earliest patents referring to these basic salts as complexes or coordination compounds is McNab No. 2,418,894, who gives'no indication in his patent as to the molecular structure of the product. As might be expected, one of the first steps employed to produce a metal salt having an intended large excess-of metal in combination was to use an unusually large excess of neutralizing 19 Claims. (Cl. 260-504) 2 agent, such as lime. A representative patent disclosing this procedure is Griesinger et al. No. 2,402,325 who suggested the use of neutralizing agent up to 220% of the theoretical amount. This large excess of neutralizing agent was employed in a process more or less conventional for producing salts or soaps excepting that the processwas carried out in the presence of steam in order to facilitate the formation ,of the product.
The work of Griesinger' was followed by the Work of Campbell and Dellinger as given in Patent No. 2,465,861. These patentees base their disclosure on the hypothesis that minor amounts of an alkaline earth metal hydroxide or carbonate can be peptized, or held in a state of coll'oidal suspension in oil by means of an oil-soluble mahogany sulphonate. Another worker in' the art who sought to combine in such complexes an excess amount of metal was Mertes' whose Patent No. 2,501,731 was granted March 28, 1950; Merte's' first prepared the normal soap and stated that such soap or soap concentrate may have additional base combined'therewith' by a'more or'less simple mixing and heating operation followed by filtering. The disclosure in Mertes appears to' i'ndic'ateqthat his product is similar to that of Campbell and Dellin'ger', in that theexcess' neutralizing agent was held in the product in the form of a colloidal suspension.
1 All of the previously enumerated processes. have been tried, not only duplicating certain of the examples given in the above-identified patents, but also using different acids and different neutralizing agents. As a result of these" experiments, it has been found that there is a definite upper limit to the amount of alkaline earthm'etal which can be held incombination or in colloidal suspension by means of these prior art processes. The grea'test'total amount of alkaline earth in tail which can possibly bethus incorporated inth produc't'by' mea'ns' of any of these prior artl rocesseshasbeen obtained when using barium and in that caseitis equal to about 2.3 timesjthe'the' oretica-l' amount present in the normal salt; For
the purpose of the present invent-m th -5 of" the total metal in the complex to the amount of meta-1' which i'si-n the form of the normal salt of the oil'solub'leor'gan ic aci'cl-willhereinafter bereferred to r as the "metal ratio? By means of the resent invention, it is now possible to obtain alkaline earth metal organic complexes which contain more metal or higher metal ratios than is possible by prior art processes. With regard to lubricants, these high metal containing complexes are for example particularly suited as detergents, and by reason of the metal concentration can be used in amounts appreciably less than other additives known in the prior art in order to attain a desired level of performance. It will also be observed that by virtue of the more eifective nature of the present complexes in lubricants, usually it will cost less to obtain a desired result, because appreciably less additive is required. The alkaline earth metal 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 complex alone is desired, it can be produced in mineral oil solutions of at least about 20% concentrations; whereas if the complex is wantedin 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.
'To the 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 principle 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-in stance, 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 different 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 producing 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 saltforming metal compound under conditions which produce a normal salt, which comprises increasing the amount of metal which will be thus combined by having present in the process mass.
((1) an amount of such metal compound substantially in excess of the stoichiometric amount required to form the normal metal salt;
(b) 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 l 10 at about 25 C.; and the salts of such organic compounds; and
(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.
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;
B. An organic compound containing an element of group VI of the periodic chart which has an atomic number less than 17, which compound is selected from the class consisting of: v
(1) An organic compound AH in which H is hydrogen and A is an organic anionic radical, having:
(a) An ionization constant in water of at least about 1X 10* at about 25 C.;
(b) A water solubility at 50 C. of
at least about 0.0005%; and
(c) In saturated aqueous solutions at about 25 C. a pH of not greater than about 7;
(2) The alkaline earth metal salts of such organic compounds;
the relative amounts of A andB used bein iii'the range of from about one equivalent of A toabout equivalents of B to about 10 equiva- -lents':o'f A to about one equivalent of B;
' C; inorganic alkaline 'earth'metal comia'ound v (1) Which is water-soluble at a temperature of 50 C. of at least0.0003% (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 metal present in the remaining components'per equivalent of A plus B;
and
51). Water, in an amount equal to at least about one mole per mole of C. II. And then maintaining the mass at a temperature and for a periodof'time sufl'icient to drive off substantially all free water and water of hydr a'itiori Which maybe present. in the above-outlined processes, following Step II, the-mass or, product can be optionally treated inaccordancewith Steps III and IV given below.
Then treating the mass or product with a 'rhaterial which in the presence of the mass or product will form a material having a higher ionization constant than the promoter, and optionally;
IV. removing from the mass or product so much of the liberated or released promoter as may have been formed by Step III.
Thefollowing examples give the preparation of a plurality of products which range in metal content from about that of the normal salt up to many times that amount.
We have found that sulphate ash and/or metal content values, and the metal ratio values calculated therefrom, are-one means for characterizing certain of the salt complexes. As the description of the invention proceeds, it will become apparent that the neutralization number of .a salt complex is'in certain instances an unreliable index of the amount of excess metal in such complex, since it is greatly affected by the type 'of inorganic alkaline earth compound emplayed and can be varied within wide limits without significantly changing the metal content of the product by treatment of them as with air, C.z,"-and:the like. v
The above is not to be construed as a statement that the neutralization number is not an importantproperty of a salt complex. .For some uses, for "example in lubricants, it is advantageoiis in certain instances to employ a salt complex of a substantially neutral character, whereas'iii dther-instances a salt complex of high alkamay has beenv found to produce the desired resuits.

Per cent sulphate ash 13.95 Metal ratio 1.67
The salt complexes formed with compounds containing barium metal possess exceptionally high metal ratios as compared to those complexes which are obtained when using other alkaline earth metal containing compounds. Consequently, in determining the maximum amount of metal which can be incorporated into a 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 metal which can be incorporated into a salt complex by conventional techniques. Furthermore, the oil-soluble petroleum sulphonic acids are exceptionally better in producing high metal content salt complexes than other types of oil-soluble organic acid compounds.
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:

Per cent sulphate ash 16.0

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 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 tehniques. Furthermore, in every instance where the salt complexproduced 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 metal ratio of the complex. 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 -l05 C. and held there for one hour while perature was raised to 150-160 C. and held at insuring thorough mixing.

The temperature of the mixture was raised to IOU- C. and held there for one hour while insuring thorough mixing. Thereafter the temperature was raised to l50-160 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 N o 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 different 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 the promoter thus liberated, leaving the end product and complex substantially free of the promoter material. A third product which is probably difierent 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 25 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 promotermaterial 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 enizab e or n com un eed s he om te Aiter a portion or th romoter mate ial. as-been t s r enera e by t eat n the i m d teprod not with acidic mate al there enerated promot r m y th n be s a at d t er from by an one o he s eral k own mean or the re enerated promoter material may be left in the mass and the latter then treatedwith an additional amount of a salt-forming material, and it will be found that the concentration of the stablyheld metal can be further increased, The folo i e e p e of such furthere eps n ou process.

By comparison, the product of Example 43 contained a sulphate ash of 23.8% whereas the 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 after treatment with CO2.

Component A-The oil soluble organic acid 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 is 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 29 it. is: possible. to first prepare: the normal. metal s lt f h Or anic acid. inthe usual. way-ibya conventional. salt-formin procedure,v and, then begin our process by utilizing such normal metal Salt as. one; of the; starting materials, it may. be more convenient to employ as the starting material. the organic acid ratherthan 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 priorgart processes. Also, as a starting material, mixtures of acids, and, salts, can be used; to; producethe complex, The variety of classes: of organic. acids; which can be, employed are.. f.or'example, sulphur acids, carboxylic acids,
phosphorus acids, etc. of the aliphatic and, cyclic types... and, the corresponding thin-acids.
More specific examples of organic acids. re the sulphur acids including sulphonic, sulphamic, sulphinic, thiosulphonic etc, and of these the sulphonicacids will find, particular application under the present invention. A more specific identification ofthe sulphonic acids is given hereinbelow.
The carboxylic acids include the fattyacids whereinthere are present at least about 12 carbonatoms, 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 acidsxare the carbamic. acids, ricinoleic acids, chlorostearic acids, nitro-lauric acids, etc. In addition to the allphatic carboxylic acids, itis intended to employ the cyclic types such as those containing a benic acids, di-octyl cyclopentane, carboxylic acids,
etc. It is also contemplated to employ the thio carboxylic acids, that is, those carboxylic acids in which one or both. of the oxygen atoms of the carboxylic. group are. replaced by sulphur.
These. carboxylic and thio-carboxylic: acids can,
be represented by the. following formulae:
I (R'):c- TCX2H. II. Rr--CX2-H wherein R is an aliphatic radical, a: is at least 1, and (RM 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, nitrocyclopentane, deca-hydronaphthalene, mercapto-deca--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 suchiasnitro, amino, hydroxy, mercapto, halogen,
.etc, Representative examplesareznitrostearic.
acids, cery1-chlorosalicu1 c acids,,chlcrcpalmi .icacids, cetylranthranilic acids, steam-mercantonaphthoic acids, etc.
The phosphorus acids include tri, and pentavalent organic phosphorus acids and the corresponding thio-acids, which: are, for example, phosphorus, phosphoric, thiophosphoric, thiophosphorous, phosphinic, posponic, thiophosphinic, thiophosphonic, etc. acids. Among the most. useful of the phosphorus acids are those represented by the following formulae:
wherein X and X are either exygfi r s lph and at least dne X and one X. is. sulphur, and R. and. R are. each either the same. or. different organic radicals or hydrogen, and wherein. at least one is an organic radical and at least one R is hydrogen and wherein at least one B is an organic radical and at least one R. is hydrogen. Therefore, such formulae include the. oil-soluble organic thio-acids of phosphorus, more particularly the organic thiophosphoric acids and the organic. thiophosphorous acids. The organic radicals R and R can be aliphatic, cyclo-aliphatic, aromatic, aliphaticand cycloaliphaticsubstituted aromatic, etc. The organic radicals R and R. preferably contain a total of at least about 12. carbon atoms in each of the above thioacid types I and II. Examples of such acids are dicapryl dithiophosphoric acids, di-(methylcyclohexyl) dithiophosphoric acids, dilauryl dithiophosphoric acids, dicapryl dithiophosphorous acids, di-(methyl-cyclohexyl) dithiophosphorous acids, lauryl monothiophosphoric acids, di-(butyl-phenyl) dithiophosphoric acids, and mixtures of two. or more of the foregoing acids.
Certain of the above. described thio-acids of phosphorus such as for example di-capryl dithiophosphoric acid are also commonly referred to as acid esters.
As indicated, our process is applicable not only when using the oil-soluble organic acid as such as one of the starting materials, but also the alkaline earth metal salts of such organic acids. The. present process will produce a high metal content organo metallic material when as one of the startin terials o e uses a y of t metal organic complexes produced by the prior art workers, such as for example, Bergstrom, Griesinger, Campbell et al., and Mertes. We thus may utilize as a starting material the end product produced by these prior art workers and from them produce the novel high metal content complex of our invention.

34 Component C'-The alkaline earth metal salt-forming compounds- The salt-forming compounds which are employed to impart to the process mass the specified amount of metalmay be broadly defined as inorganic alkaline earth metal compounds wherein anionic radicals maybe, for example, hydroxyl, oxide, carbonate, lei-carbonate, sulphide, hydrosu-lphide, halide, hydride, amide, basic carbonate, etc. Of the inorganic alkaline earth metal compounds, good results are obtained with those having a water solubility of at least about 0.G003-% at 50 0., and preferably at least about 0.066%. Still more preferred are those inorganic alkaline earth metal compounds, saturated aqueous" solutions of which give an alkaline reaction or pH value greater than 7.
To further illustrate the large number' and variety of'classes of inorganic compounds which can be emplqyed, specific examples thereoi are enumerated below,

Inour process, the; step of treating withan acidic material" such as carbon dioxide or air has the eiiect. of freeingfrom the immediate comp x P duct formed at leas a n the promoter used. hus the presence inthe immediate complex product ofthe promoter material, in combined form, clearly distinguishes the immediate complex product from any metal organic complex type material heretofore produced. Moreover, the nature of the product formed by regenerating from the immediate end product at least a portion of the promoter material leaves that complex with a composition which is quite different from the other prior art metal organic complexes previously produced. It is recognized that in accordance with the present invention, the alkaline earth metal salt of the ionizable organic compound can be employed as the promoter in forming the salt complex. However, when such a salt is used as the promoter and the resulting complex is treated with an acidic material, the metal-free ionizable organic compound is freed from its salt.
For the purpose of releasing the ionizable organic compound used as a promoter from the complex, an important feature or characteristic of the acidic material is that it must, when present in the mass containing the complex, possess an ionization constant higher than the ionizable organic compound used as the promoter. Thus, for the purpose of this specification and the appended claims, it is to be understood that 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 following are additional specific examples of acidic materials, viz.: HCl, S02, S03, CO2, air (considered acidic because of CO2 content), N02, H28, N203, PC13, 39012, C102, HzSe, BF3, CS2, COS, etc.
It is to be understood, however, that all acidic materials are not equivalent for the purposes of the present invention, but that under certain conditions, some are more effective or desirable than others. I
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.
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 technique employed therefor.
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 compound 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 waterwhich might be present;
(1)) The inorganic alkaline earth metal compound in a dry state 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;
(0) The acid of the desired salt of organic acid is mixed with the promoter, 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;
(d) In any of the methods discussed herein for preparing the salt complex, a substantial in-. crease 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 pre paring the salt complex, the step of removing substantially all of the water which is present is accomplished at a temperature not substantially in excess of 350 0., preferably about C. to 200 C. The technique employed to remove the water includes, for example, a conventional fiash 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 the last 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 Generally, the time required to effect substantial removal of water is at least about 15 minutes or less and can be as high as 10-15 hours or more. Usually, however, it is most convenient to employ atmosbheric pressureior. such an. operation. and cone sequently it requires aboutv 1 toffijholirsgto re.-.v mo substa ial y all ofthe waterf m the. pr ce mixture twas observed that atisfactor c mp ex s ar ob ained w en using any Ofthe. techniques described aboye, and that the final Water ontent can be. up. ta-a out 2%. or more.

It is apparent that high metal ratios are possible under this theory. Another theory is based upon an electronic interpretation. For example, in the case of the neutral sulphonate, the charges are distributed as follows:
The electron octets around the two oxygen atoms which are not-attached to a metal atom give to each of these atoms a unit negative charge, thus leaving the sulphur atom with a double positive charge.
When the-sulphonate, excess inorganic metal compound, promoter, and water are reacted according to the present invention, a basic promoter salt AXMOH is presumed to be formed. This normally oil-insoluble salt 'dissolves in the reaction mixture because of the electronic attracting force known-as a hydrogen bonding. structurally this can be shown as:
R- s y-o n ..H... o-m-xx and (b) O-...H...OMXA
Structure (41.) would have a metal ratio of 3.0, and structure (5) 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,"
The AX- ions may then react with M(OH)2 to produce more 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 appears to function as a carrier for the M(OH)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 thatthe'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, transmissions, gears, etc. as well as in torque converter oils. Other suitable uses for such complexes are in asphalt emulsions, insecticidal compositions, fireproofing 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, gumsolvent compositions, fat splitting agents, bonding agent for ceramics and asbestos, asphalt improving agents, flotation agents, improving agents for hydrocarbon fuels such as e. g., gasolene and fuel oil, etc.
