Diesel compositions comprising organometallic complexes.

Technical field

The invention relates to diesel compositions which are suitable for diesel engines (or diesel or diesel engines) equipped with a particulate trap exhaust system. This fuel contains an effective amount of an organometallic complex compound that reduces the ignition temperature of the discharged particles trapped in the trap. The organometallic compound is dissolved or stably dispersed in the diesel fuel and is derived from (i) an organic compound containing at least two functional groups attached to the hydrocarbon moiety, and (ii) a metal reactant capable of forming a complex compound with the organic compound . The metal may be any metal capable of lowering the ignition temperature of the exhaust particles, which may preferably include sodium, Na, potassium K, magnesium Mg, calcium Ca, strontium Sr, barium Ba, vanadium V, chromium Cr, molybdenum Mo, iron Fe , cobalt Co, copper Cu, zinc zinc, boron B, lead Pb, antimony Sb and mixtures of two or more of these metals.

BACKGROUND OF THE INVENTION

Diesel (or diesel or diesel) engines are used as engines for cars and machines with high load capacity because they have relatively low fuel consumption and better mileage. However, due to the operating characteristics, these diesel engines emit large amounts of soot in the form of very fine condensed particles or agglomerated particles into the ambient air as compared to gasoline engines. These particles or condensates are sometimes referred to as diesel soot, and emissions of these particles or soot are polluting the environment and are therefore undesirable. In addition, these diesel blacks have been found to be rich in multi-ring condensed hydrocarbons, some of which have been identified as carcinogenic. In view of the above, it has been proposed in these diesel engines to use particle traps or filters that are capable of retaining soot particles or condensed particles prior to discharge into the atmosphere.

A common embodiment of such traps or filters is that they consist of a heat-resistant filter element made of porous ceramic or metal fibers and an electric heating unit for heating and igniting the carbon particles trapped on the filter element. The use of this electric heater unit is necessary since the temperature of the exhaust gases discharged from the diesel engine under normal operating conditions is not sufficient to burn such accumulated soot trapped in the filter or trap. Generally, temperatures ranging from about 450 to 600 ° C should be used, the heater unit allowing the temperature of the exhaust gas to be increased to the level required to ignite the particles trapped and collected in the trap and thereby recover. this trap. In other words, carbon black particles are deposited in the trap during operation and this trap could eventually become clogged, causing operating problems due to the build-up of back pressure. The prior art heat recovery unit traps described above do not completely solve this problem since the exhaust gas temperature is below the ignition temperature of the carbon particles during normal engine operation, and the heat generated by the heat recovery unit is dissipated together with these exhaust volumes. exhaust gases. Alternatively, the high trap temperatures can be achieved by periodically enriching the combustion air / fuel mixture in the diesel engine, thereby increasing the exhaust gas temperature. However, this increase in temperature can cause the regeneration process to be put out of operation due to the occurrence of high localized temperatures, and at the same time, it can damage the trap.

It has also been proposed in the prior art to control particle formation in a trap by lowering the particulate temperature of the particles so that the particles are combusted at the lowest possible temperatures. One method of reducing this ignition temperature is by adding a combustion enhancer to the exhaust emissions, and the most practical way of adding the combustion enhancer to the exhaust is to add the combustion enhancer directly to the fuel. As combustion enhancers and added to fuels, including diesel, there were. according to the prior art it is proposed to use the compounds by the medium.

According to U.S. Pat. The Environmental Protection Agency (EPA) has estimated that the average sulfur content of diesel used in motorway vehicles is approximately 0.25% by weight, with the obligation to reduce this level to a maximum of 0.05% by weight from 1 October 1993. The European Community also requires a minimum cetane number of 40 (or 35% of the maximum flavoring level) for diesel fuel to be achieved. The aim of these regulations is to reduce the sulphate content in particulate form and the carbon and organic particulate emissions. Federal Register, Vol. 55, No. 162, Aug. 21, 1990, pp. 34120-34151. So far, however, they have not been implemented in practice. no low-sulfur diesel fuel compositions or technologies to meet these emission requirements. One way to meet these requirements to reduce these emissions is to develop a low sulfur diesel additive that can be effectively used under conditions of applying low sulfur diesel to reduce the ignition temperature of carbon blacks that are trapped in the carbon black. in the diesel engine trap.

R R XR R where:

X oxygen or sulfur,

R is hydrogen or hydrocarbyl,

R * represents a hydrocarbylene group or a hydrocarbylidene group, and a represents a number (such as a number from zero to about

10).

As used herein, the term hydrocarbyl and like derived terms such as hydrocarbylene, hydrocarbylidene, hydrocarbon-based, etc. in the context of the present invention means a chemical group having a carbon atom directly attached to the rest of the molecule and having a hydrocarbon or predominantly hydrocarbon character. By these groups are meant, for example, the following residues:

(1) hydrocarbon groups, i.e., aliphatic groups (such as alkyl or alkenyl groups), alicyclic groups (such as cycloalkyl or cycloalkenyl groups), aromatic groups, aromatic radicals substituted with aliphatic and alicyclic groups, aliphatic and alicyclic radicals substituted with aromatic groups and the like, as well as cyclic groups in which the ring is closed by another part of the molecule (i.e., any two of said substituents may together form an alicyclic group). These groups are well known to those skilled in the art. Examples of such groups include methyl, ethyl, octyl, decyl, octadecyl, cyclohexyl, phenyl, etc.

(2) Substituted hydrocarbon groups, i.e. groups containing non-hydrocarbon substituents, which in the context of the present invention do not predominantly alter the hydrocarbon nature of the group. Suitable groups of this nature will be apparent to those skilled in the art. Examples of such groups include halogens, hydroxy, nitro, cyano, alkoxy, acyl, etc.

(3) Hetero groups, that is to say, groups which are predominantly hydrocarbon in the context of the present invention and which contain in the chain or ring that otherwise would be carbon atoms other than carbon atoms. It will be appreciated by those skilled in the art that suitable heteroatoms include, for example, nitrogen, oxygen, and sulfur.

In general, for each 10 carbon atoms in the hydrocarbyl group there are at most about three substituents or heteroatoms, preferably at most one substituent or heteroatom.

These multi-ring compounds may be of the fused type wherein the aromatic core is attached at two sites to another core, such as naphthyl, anthranyl, azanaphthyl, and the like. These multi-ring moieties may also be linked by a bond, in which case at least two ring systems (comprising either single-ring or multi-ring moieties) are joined together by bridging bonds.

In some cases, more may be present. than one bridged bond between two aromatic nuclei, such as a fluorene nucleus having two benzene nuclei linked by both a methylene bond and a covalent bond. This ring system can in fact be considered to have three rings, but only two of them are aromatic rings. In a conventional embodiment, however, the aromatic group contains only the carbon atoms in the aromatic nucleus itself (plus any optionally present alkyl or alkoxy substituents).

The aromatic group may be a single ring aromatic group represented by the general formula:

in which it means:

Ar is a single ring aromatic group (such as benzene) containing from 4 to 10 carbon atoms,

Q individually each represents a lower alkyl group, a lower alkoxy group or a nitro group, and m is a number from 0 to 4.

A specific example of these single ring aromatic groups is the following:

The preparation of aromatic Mannich compounds can be accomplished by a number of different methods well known in the art. According to one of these methods, component (A1), i.e., a hydroxyl and / or thiol-containing aromatic compound, component (A-2), which is an aldehyde or ketone, and component (A-3), is an amine compound, wherein the reaction mixture is then heated to complete the desired reaction. The reaction temperature may be from about ambient temperature to about the decomposition temperature of any component used in the process or product, which is a Mannich compound. During this reaction, water can be removed, for example, by condensation. In carrying out this reaction, it is convenient to use a solvent such as an oil of the aromatic type. The amount of the various reactants used is preferably selected in moles per mole to correspond to an equivalent number of moles of component (A1) and (A-2) for each secondary amino group of component (A-3) or twice the number of moles of component (A1); (A-2) for each primary amino group of component (A-3), but higher or lower amounts than indicated may also be used.

In another method, the aromatic Mannich compound may be prepared by first introducing into the reaction vessel an aromatic compound containing a hydroxyl and / or thiol group, i.e. component (A-1), and an amine compound (A-3). Typically, the aldehyde or ketone (component (A-2)) is then rapidly added to exotherm and the reaction mixture is maintained under gentle heating such that the temperature is in the range of about 60 ° C to about 90 ° C. It is preferred to keep the temperature below the boiling point of water, or in other words, water vapor will be bubbled through the reaction mixture, which could cause operational problems. After substantially completing the above reaction, the water by-product is removed by any suitable means, such as evaporation, which may be accomplished, for example, by applying vacuum, applying fading (heating water), heating, and the like. Very often, these processes employ nitrogen injection at temperatures in the range of about 100 ° C to about 120 ° C. Lower temperatures can also be used. In another embodiment, the reaction between components (A-1), (A-2) and (A-3) is carried out at a temperature below 120 ° C.

(19) Boronated and acylated amines.

The component (i) of the organometallic complex of the present invention may, in another embodiment, be a boronated acylated amine. These compounds may be prepared by first reacting a hydrocarbon-substituted succinic acid-producing compound (sometimes referred to herein as a succinic acylating agent) with at least about half the equivalent of an amine containing at least one hydrogen atom attached to the nitrogen group per equivalent above. said succinic acid-producing compounds. The nitrogen-containing compositions obtained by this process are usually complex mixtures. These nitrogen-containing compositions are sometimes referred to as acylated; amines. These nitrogen-containing compositions are then borated. wherein the reaction is reacted with a boron compound selected from the group consisting of boron oxide, boron halides, boric acids, boron amides and boron acid esters.

These acylated amines have been described in U.S. Pat many patents United States belonging to the state of the art techniques, including the following patents: 3,172,892 3,341,542 3 630 904 3,127,707 3,346,493 3 632 511 3,272,746 3,444,170 3 787 374 3,316,177 3,541,012. 3,454,607 4 234 435

These aforementioned United States patents are incorporated herein by reference only to illustrate the process for preparing the above acylated amines used in the present invention.

In general, the conventional route to preparing the above acylated amines involves reacting said hydrocarbon-substituted succinic acid compound (i.e., carboxylic acid acylating agent) with an amine containing at least one hydrogen attached to the nitrogen atom (i.e., H-N =). Examples of such succinic acid-producing compounds substituted with a hydrocarbyl group are succinic acids, anhydrides, halides and esters. The number of carbon atoms in this hydrocarbon substituent in this succinic acid producing compound can vary within a very wide range, provided that the organometallic complex prepared by this component is soluble or stably dispersible in diesel fuel. The hydrocarbon substituent typically contains on average at least about 10 aliphatic carbon atoms, preferably at least about 30 aliphatic carbon atoms, and even more preferably at least about 50 aliphatic carbon atoms.

The sources of this substantially hydrocarbon substituent are mainly substantially saturated high molecular weight petroleum fractions and substantially saturated olefin polymers, especially polymers of monoolefins having 2 to 30 carbon atoms. Particularly suitable polymers in this regard are polymers of 1-monoolefins, such as ethylene, propene,

1-butene, isobutene, 1-hexene, 1-octene, 2-methyl-1-heptene, 3-cyclohexyl-1-butene and 2-methyl-5-propyl-1-hexene. Similarly, internal polymers, i.e. olefins, in which the olefinic bond is not at the terminal position can be suitably used. By way of illustration, examples are given

2-butene, 3-pentene * and 4-octene.

For the above purposes, it is also possible to use the internal olefin polymers mentioned above with other copolymerizable olefinic materials such as aromatic olefins, cyclic olefins and polyolefins. Such copolymers include, for example, those prepared by polymerizing isobutene with styrene, isobutene with butadiene, propene with isoprene, ethylene with piperylene, isobutene with chloroprene, isobutene with p-methylstyrene, 1-hexene with 1,3-hexadiene, 1-octene with 1-hexene, 1-heptene with 1-pentene-> 3-methyl-1-butene with

100 ALIGN!

1-octene, 3,3-dimethyl-1-pentene with 1-hexene, isobutene with styrene and piperylene, etc.

The relative proportion of monoolefin relative to the second monomer used in the copolymer affects the stability and solubility of the end product obtained from these copolymers in diesel. Thus, in view of these requirements regarding oil solubility and the stability of the end products, considerably aliphatic and substantially saturated copolymers are contemplated for the present invention, i.e. the copolymers should contain at least 80% by weight, preferably at least about 95% by weight of units derived from aliphatic monoolefins and up to about 5% olefinic bonds based on the total number of carbon-carbon covalent bonds. In most cases, the percentage of olefinic bonds should be less than about 2% of the total amount of carbon-carbon covalent bonds.

Specific examples of the above copolymers include a copolymer containing 95% by weight of isobutene and 5% by weight of styrene, a terpolymer containing 98% by weight of isobutene, 1% by weight of piperylene and 1% by weight of chloroprene, a terpolymer containing 95% by weight of isobutene, 2% by weight. -butene and 3% by weight of 1-hexene, terpolymer containing 80% by weight of isobutene, 20% by weight of 1-pentene and 20% by weight of 1-octene, copolymer containing 80% by weight of 1-hexene and 20% by weight of 1-heptene, terpolymer containing 90% % isobutene, 2% cyclohexene and 8% propene, and a copolymer containing 80% ethylene and 20% propene.

101

Another source of substantially hydrocarbon groups is saturated aliphatic hydrocarbons such as highly refined high molecular weight white oils or synthetic alkanes, such as those obtained by hydrogenation of the high molecular weight olefin polymers described above, or high molecular weight olefinic materials.

In a preferred embodiment of the invention, it is preferred to use olefinic polymers having a number average molecular weight (Mn) of from about 700 to about 10,000. In one embodiment, said substituent is derived from polyolefins characterized by an Mn of about 700 to about 10,000 and a Mw / Mn ratio ranging from 1.0 to about 4.0.

To prepare said substituted succinic acylating agents, one or more of the above polyalkanes is reacted with one or more acidic reagents selected from the group consisting of maleic or fumaric reagents such as acids or anhydrides. Typically, the maleic or fumaric reagents are maleic acid, fumaric acid, maleic anhydride or a mixture of two or more thereof. Preferably, the maleic reagents are preferred over the fumar reagents since the maleic reagents are more readily accessible and generally more readily react with said polyalkenes (or derivatives thereof) to prepare substituted succinic acid-producing compounds of the invention . It is particularly preferred to use maleic acid, maleic anhydrides and mixtures thereof as reactants. Due to easy

Maleic anhydride is usually used to facilitate the reaction.

The term maleic reagent is often used in the description of the present invention for convenience and brevity. In this context, it should be noted that where the term is used, it generally means acidic reactants selected from the group consisting of maleic and fumaric reactants, including mixtures of these reactants. It should also be noted that the term succinic acylating agent as used herein includes substituted substituted succinic acid-producing compounds.

One method of preparing the substituted succinic acylating agent of the present invention is described in part in U.S. Pat.

No. 219,666, which is incorporated herein by reference in order to illustrate one embodiment of the above-described succinic acylating agents. This process is usually referred to as a two-step process. The process comprises, in a first stage, the chlorination of said polyalkene and in a second stage, the reaction of the chlorinated polyalkene thus obtained with a maleic reagent.

Another variant of the process for preparing the above substituted succinic acylating reagents is the process disclosed in U.S. Pat.

No. 912,764 and U.S. Patent 1,440,219, both of which are incorporated herein by reference only, illustrating other variants of the process. According to this process, said polyalkene and a maleic reagent are first reacted, the reaction of the two components

103 takes place with heating and direct alkylation. Upon completion of the direct alkylation step above, chlorine is introduced into the reaction mixture to promote this reaction of the remaining unreacted maleic reagents.

Another process for preparing the substituted succinating acylating agents of the present invention is the so-called one-step process. This process is described in United States Patent Nos. 3,215,707 and 3,231,587. Both of these patents are herein incorporated by reference only illustrating another variation of the process for preparing the above compounds. This one-step process involves the preparation of a mixture of polyalkene and a maleic reagent containing the necessary amount of both to prepare the desired substituted succinic acylating agent of the present invention. That is, at least one mole of maleic reagent per mole of polyalkylene must be present in the reaction mixture to have at least one succinate group for each equivalent weight of the substituent groups present in the desired product. Chlorine is then introduced into the mixture. this is usually done by bubbling chlorine gas through the mixture while stirring.

The amines which are reacted with the succinic acid-producing compounds to prepare acylated amines include any of the amines of formula (A-3) described above in connection with the preparation of the aromatic Mannich compounds of the invention. A preferred group of these amines includes such amines such as the alkylene polyamines represented by the general formula A-3-3,

104 above.

The acylated amines obtained by the reaction of the succinic acid-producing compounds and the above-mentioned amines can be amine salts, amides, imides, imidazolines as well as mixtures thereof. In preparing these acylated amines, one or more succinic acid-producing compounds and one or more amines are heated, optionally in the presence of a conventional liquid, which is a substantially inert organic liquid solvent / diluent, at elevated temperature, typically in the range of about 80 ° C to the decomposition temperature of the mixture or product so prepared. Typically, a temperature in the range of about 100 ° C to about 300 ° C is typically used, provided the temperature of 300 ° C does not exceed the decomposition temperature.

The succinic acid compound and the amine are reacted in amounts sufficient to provide a ratio of at least about one-half equivalent of the amine to one equivalent of the acid-producing compound. Generally speaking, the maximum amount of amine present is about 2 moles per equivalent of the succinic acid producing compound. For the purposes of the present invention, one amine equivalent is an amount of amine that corresponds to the total weight of the amine divided by the total number of nitrogen atoms present. It follows from the foregoing that octylamine has an equivalent weight equal to its molecular weight, ethylenediamine has an equivalent weight equivalent to half its molecular weight, and aminoethylpiperazine has an equivalent weight equivalent to one third of its molecular weight. The number of equivalents of succinic acid-producing compound depends on the number

The 105 carboxyl functions present in the hydrocarbon-substituted succinic acid-producing compound. It follows from the above that the number of equivalents of a succinic acid-producing compound which is substituted with a hydrocarbon group varies according to the number of succinic groups present therein, typically two equivalents of acylating agent per succinic group in the acylating reagent. Conventional methods (such as acid number, saponification number) can be used to determine the number of carboxyl functional groups to determine the number of equivalents of acylating reagent available for reaction with the amine. Further details and examples of procedures for preparing these acylated amines can be found, for example, in U.S. Patent Nos. 3,172,892, 3,219,666, 3,272,746 and 4,234,435, the disclosures of which are incorporated herein by reference.

The acylated amine thus obtained is then reacted with at least one boron compound selected from the group consisting of boron trioxide, boron halides, boric acids, boron amides and boronic acid esters. The amount of the boron compound reacted with the acylated amine intermediate is generally selected to be sufficient to provide a ratio of about 0.1 atomic boron per mole of acylated amine to about 10 atomic boron per nitrogen atom in the said acylated amine. More preferably, the amount of boron compound is sufficient to provide a ratio of 0.5 atomic boron per mole of acylated amine to about 2 atomic boron per atom of nitrogen used.

106

Suitable boron compounds which can be used for the above purposes include boron oxide, boron oxide hydrate, boron oxide, boron trifluoride, boron tribromide, boron trichloride, boric acids such as boric acid [i.e. alkyl-B]. (OH) ₂ or aryl-B (OH) ₂ ], orthoboric acid (i.e. H ₃ BO ₃ ), tetraboric acid (i.e. H ₂ B ₄ O ₇ ), metaboric acid (i.e. HBO ₂ ), boron anhydrides, boron amides and various esters derived from said boron acids. A common method for introducing boron-based reactants into the reaction mixture is to use complex boron trihalide compounds with ethers, organic acids, inorganic acids, or hydrocarbons. Such complexes are well known in the art, and include boron trifluoride / triethyl ester, boron trifluoride / phosphoric acid, boron trichloride / chloroacetic acid, boron tribromide / dioxane and boron trifluoride / methyl ethyl ether.

Specific examples of boric acids include methylboric acid, phenylboric acid, cyclohexylboric acid, p-heptylphenylboric acid, and dodecylboric acid.

Examples of boronic acid esters are, in particular, mono-, di- and tri-organic boronic esters of alcohols or phenols, such as methanol, ethanol, isopropanol, cyclohexanol, cyclopentanol,

1-octanol, 2-octanol, dodecanol, behenyl alcohol, oleyl alcohol, stearyl alcohol, benzyl alcohol,

2-butylcyclohexanol, ethylene glycol, propylene glycol, trimethylene glycol, 1,3-butanediol, 2,4-hexanediol,

1,2-cyclohexanedioT, 1,3-octanediol, glycerol,

107 pentaerythritol, diethylene glycol, carbitol, cellulose, triethylene glycol, tripropylene glycol, phenol, naphthol, p-butylphenol, o, p-diheptylphenol, n-cyclohexylphenol,

2,2-bis- (p-hydroxyphenyl) propane, polyisobutene-substituted phenol (1500 molecular weight), ethylene chlorohydrin, o-chlorophenol, m-nitrophenol,

6-bromooctanol and 7-ketodecanol. Lower alcohols, 1,2-glycols and 1,3-glycols, i.e. those containing less than about 8 carbon atoms, are particularly suitable for the preparation of boronic esters.

Methods for preparing boronic acid esters are well known in the art and have been published in many publications (see, for example, Chemical Reviews, pp. 959-1064, Vol. 56). One of these methods involves reacting boron trichloride with 3 moles of alcohol or phenol to give the triorganic borate. Another method involves reacting boron trioxide with an alcohol or phenol. In a further procedure, a direct esterification of tetraboric acid with 3 moles of alcohol or phenol is carried out. Another method involves direct esterification of boric acid with glycol to form, for example, cyclic alkylene borate.

The reaction of the acylated amine with boron compounds can be carried out in a simple manner by mixing the reactants at the desired temperature. Alternatively, an inert solvent may be used, although in some cases its use may be highly desirable, especially when highly viscous or solid reactants are present in the reaction mixture. The inert solvent may be a hydrocarbon solvent such as benzene, toluene, naphtha, cyclohexane, n-hexane or a mineral oil. The temperature of this reaction can be very wide.

108

Typically, the temperature is preferably in the range of about 50 ° C to about 250 ° C. In some cases, the temperature may be 25 ° C or even lower. The upper limit of this temperature range is the decomposition temperature of the particular reaction mixture and / or product.

This reaction is usually completed in a very short interval, such as 0.5 to 6 hours. Upon completion of this reaction, the product is dissolved in a solvent and the solution is purified by centrifugation or filtration if there is turbidity or solids. Usually, however, the product thus obtained is sufficiently pure so that further purification is unnecessary or only possible.

This reaction of the acylated amine with boron compounds provides a boron-containing product and substantially all of the nitrogen originally present in the acylated amine reactant. It is believed that the result of this reaction is the formation of a complex between boron and nitrogen. The complex may contain in some cases more than one atomic boron and one atomic nitrogen, and in other cases the complex may contain more than one atomic nitrogen and one atomic boron. The nature of this complex is not yet fully explained.

Although the exact stoichiometric composition of the complex thus formed is not known, the relative proportions of the reactants used in this process are mainly chosen according to the products thus obtained for the purposes of the present invention. Accordingly, suitable reaction products are obtained from those reaction mixtures in which the reactants are present in relative proportions

109 corresponding to about 0.1 atomic boron for each mole of acylated amine to about 10 atomic boron for each atomic portion of nitrogen in said acylated amine to be used. Preferred amounts of the reactants used are those corresponding to about 0.5 atomic boron per mole of acylated amine to about 2 atomic boron fractions per mole of acylated amine. To illustrate these ratios, the amount of boron compound containing one boron atom per molecule used with one mole of an acylated amine containing five nitrogen atoms per molecule ranges from about 0.1 mole to about 50 moles, preferably from about 0.5 mole to about 10 moles.

These boronated acylated amines are further suitable components (i) for preparing the organometallic complex compounds of the present invention. In another embodiment, the boronated acylated amines are suitable components of the organometallic complexes of the invention.

Performing this reaction involves mixing four moles of alcohol or phenol with one mole of phosphorus pentasulfide at a temperature in the range of about 20 to about 200 ° C. This reaction releases hydrogen sulfide. Analogous compounds of these oxygen-containing acids can be prepared in a conventional manner by treating dithionic acid with water or steam, which results in the replacement of one or both of the sulfur atoms.

Suitable phosphorous-containing acids in this context include phosphorous and sulfur-containing acids. Such acids include such compounds according to the invention in which at least X ¹ or X ² is sulfur, and preferably both X ³ and X ⁴ are oxygen and m is 1. Also, it is possible to use mixtures of said acids.

Each of R ¹ and R ² is independently a hydrocarbyl group, i.e. preferably a group not containing an acetylenic bond and usually also an ethylenic unsaturation, which groups contain about 1 to about 50 carbon atoms, preferably about 1 up to about 30 carbon atoms and even more preferably about 3 to about 18 carbon atoms. In one preferred embodiment of the invention, each of R ¹ and R ² may be, for example, isopropyl, isobutyl, 4-methyl-2-pentyl,

113

2-ethylhexyl, iso-octyl, etc. Each of R ¹ and R ² may be identical to or different from each other, and either or both may be a mixture of different hydrocarbon residues. These substituents R ¹ and R ² preferably represent each alkyl group and most preferably a branched alkyl group.

The reaction to form said phosphorylated acylated amines can be carried out by mixing the components (P-1), (P-2) and (P-3) in any order. All of these reactants can be mixed at room temperature and then heated to the desired temperature above 80 ° C for acylation. This reaction can be similarly performed by first reacting components (P-2) and (P-3) and then acylating the intermediate with component (P1) or first acylating component (P-2). component (P1) and then reacting the acylated amine so obtained with component (P-3). Preferably, the acylation is carried out at temperatures in the range of about 100 ° C to about 300 ° C, more preferably in the range of about 150 to about 250 ° C.

This acylation is accompanied by the formation of water. The water thus formed can be removed by heating the reaction mixture to a temperature of 100 ° C or higher. This reaction can be facilitated by bubbling the reaction mixture during heating with an inert gas such as nitrogen. It is also possible to facilitate this reaction by using an inert solvent in the reaction mixture which forms a common distillable azeotropic mixture.

114 with water. Examples of such solvents include benzene, n-hexane, toluene, xylene, etc. The use of these solvents allows removal of water at substantially lower temperatures, such as 80 ° C.

The relative proportions of reagents used in this process are derived from the stoichiometric ratios corresponding to the reaction and the intended use of the products obtained by the process for the purposes of the present invention. The minimum amount of components (P-1) and (P-3) used is about 0.5 equivalents of each of (P-1) and (P-3) for each mole of component (P-2). The maximum amount of these components (P-1) and (P-3) used depends on the total number of equivalents of the component (P-2) used.

For the preparation of these acylated phosphorus-containing amines, it is assumed that the number of equivalents of the amine compound (P-2) corresponds to the number of HN < groups in the amine. The equivalent weight of the amine represents the total weight of the amine divided by the total number of HN <groups present. It follows from the above that ethylenediamine has an equivalent weight equivalent to one half of its molecular weight and tetraethylenepentamine has an equivalent weight equivalent to one fifth of its molecular weight. For example, the equivalent weight of commercially available amine mixtures can be determined by dividing the atomic weight of nitrogen (14) by the percentage of nitrogen contained in the amine. It follows that the amine mixture containing 34% nitrogen will have an equivalent weight of 41.2. The total number of amine equivalents can be determined by dividing the total weight of the amine by its equivalent weight.

115

The total number of equivalents of acylating agent (P-1) depends on the total number of carboxylic functions (such as carboxylic acid groups or functional derivatives thereof) present in the acylating agent. It follows that the number of equivalents of acylating agent will vary according to the number of carboxyl groups present in the acylating agent. In determining the number of equivalents of an acylating agent, carboxylic functions which, as carboxylic acids, are incapable of reacting with the acylating agent are disregarded. In general, however, it is contemplated that there is a ratio of one equivalent of acylating agent to each carboxyl group in the acylating agent. For example, in the case of acylating agents resulting from the reaction of one mole of olefin polymer and one mole of maleic anhydride, two carboxyl groups should be contemplated herein. In order to determine the number of carboxyl functions, simple prior art methods (such as acid number, saponification number) can be used to determine the number of equivalents of the acylating agent to be reacted with the amine compound.

The equivalent weight of component (P-3) can be determined by dividing the molecular weight of component (P-3) by the number of -PXXH groups. This number of groups is usually determined from the structural formula of component (P-3) or empirically by conventional titration methods known in the art. The number of equivalents of component (P-3) can be determined by dividing the weight of component (P-3) by the equivalent weight of that component.

Maximum combined number of equivalents of components (P-1) and (P-3) that can be reacted with one mole

116 component (P-2) is equivalent to the number of HN <groups. If an excess of components (P-1) and (P-3) is used, this excess does not participate in this reaction. On the other hand, if the total amount of components (P-1) and (P-3) used is less than the maximum amount, the products thus obtained will contain an unreacted proportion of free amine nitrogen atoms. Suitable products according to the present invention are those obtained using components (P1) and (P-3) in relative amounts falling in an equivalent ratio ranging from about 0.5: 4.5 to about 4.5: 0.5 .

As a specific example illustrating the limitation of the relative proportions of reactants used, one mole of tetraalkylenepentamine is reacted with about 0.5 to about 4.5 equivalents of polyisobutene substituted succinic anhydride and about 0.5 to about 4.5 equivalents. phosphorodithionic acid.

Reaction procedure for the preparation of organometallic complex.

The reaction to form the above organometallic complex compounds of the invention from components (i) and (ii) can be carried out in a simple manner by simply mixing the reactants at the desired temperature. The reaction may be carried out at a temperature of at least about 80 ° C. In some cases, the reaction temperature may be so low that room temperatures such as about 20 ° C can be used. The upper limit of this reaction temperature is the decomposition temperature of the reaction mixture, temperatures above 250 ° C are rarely necessary.

Preferably, the reaction is carried out in the presence of a diluent or solvent in which the reactants used are soluble or in which the reaction product is soluble. The solvent may be any liquid inert solvent such as benzene, xylene, toluene, kerosene, petroleum oil, chlorobenzene, dioxane or the like.

The relative amounts of components (i) and (ii) vary widely. Typically, at least about 0.1 equivalents of component (ii) is used per equivalent of component (i). The amount of component (ii) may preferably be from about 0.05 to about 1 equivalent of component (ii) per equivalent of component (i),

124 according to an even more preferred embodiment ranging from about 0.1 equivalent to about 0.4 equivalents of component (ii) per equivalent of component (i). The equivalent weight of component (i) is related to the number of functional groups contained in component (i) that are capable of complexing with the metal contained in component (ii). Thus, for example, the weight of propylene triamer nitrophenol equivalent is equal to half the molecular weight of the compound. The equivalent weight of component (ii) is related to the number of metal atoms present in the component. Thus, for example, the weight of cuprous oxide equivalent corresponds to one-half its molecular weight and the weight of cuprous hydroxide equivalent corresponds to the molecular weight of the compound. Also, the relative amount of component (ii) is to some extent related to the coordination number of the metal in the reaction component (ii). For example, up to six equivalents of component (i) may be combined with one equivalent of a metal reactant, where the metal has a coordination number of six.

The product obtained by reacting component (i) with component (ii) is an organometallic complex. That is, the reaction of said components results in a combination of the functional groups contained in component (i) with the metal component (ii) via a second metal valency. The exact nature of these organometallic complexes is not yet known. For the purposes of the present invention, it is only essential that these complexes be sufficiently stable in diesel fuel to be used in a diesel engine equipped with a particulate trap in the exhaust system to reduce the ignition temperature of the exhaust particles trapped therein.

If said metal is iron Fe, manganese Mn or copper Cu in combination with lead Pb, cobalt Co, nickel Ni, zinc Zn, chromium Cr, antimony Sb, tin Sn or vanadium V, then component (i) is another substance than salicylaldehyde.

When said metal is cobalt Co, Cu medium or Ni nickel, component (i) is other than salicylaldehydnitroanil. If the metal is cobalt Co or Cu, then component (i) is a substance other than malonaldehyde dinitroanil. Component (i) is a substance other than β-diketone.
