The residual chlorine content of a polyolefin-substituted carboxylic acylating agent formed by a halogen-assisted reaction of a polyalkene and at least one olefinic, monounsaturated mono- or dicarboxylic acid, anhydride or ester, is reduced when the reaction is conducted in the presence of a controlled amount of a metal compound.

Method of forming polyalkene substituted carboxylic acid compositions

A modified lubricating oil detergent that is the reaction product of an oil soluble detergent comprising an alkali- or alkaline earth metal hydrocarbyl phenate, carboxylate or sulfonate and an &#x3b1;, &#x3b2;-unsaturated carbonyl compound; and lubricating oil compositions containing a combination of such a modified detergent and a nitrogen-containing dispersant.

Modified detergents and lubricating oil compositions containing same

A process for making an additive comprising one or more oil-soluble or oil-dispersible molybdenum-sulfur compounds, said process comprising the steps of: The additive has improved color characteristics and a lubricating oil composition comprising said additive is more benign to corrosion of metals.

Molybdenum-sulfur additives

Lubricating oil compositions providing superior soot dispersing characteristics, which contain a combination of a high molecular weight dispersant and a soot dispersant comprising a linked aromatic oligomer.

Lubricating oil composition

Soot induced kinematic viscosity increase of lubricating oil compositions for diesel engines equipped with EGR systems can be ameliorated by selection of viscosity modifier, lubricating oil flow improvers, detergents and/or dispersants.

Lubricating oil compositions

Low molecular weight oxazine ring-containing Mannich base condensates of hydroxy aromatic compounds, aldehyde; and amine. Such compounds are useful as soot dispersants in lubricating oils when used alone, or in combination with high molecular weight dispersants.

Hydroxy aromatic Mannich base condensation products and the use thereof as soot dispersants in lubricating oil compositions

A dispersant that is a reaction product of a polyalkenyl-substituted mono- or dicarboxylic acid, anhydride or ester; and a polyamine, wherein the reaction product has from greater than about 1.3 to less than about 1.7 mono- or di-carboxylic acid producing moieties per polyalkenyl moiety, and the polyalkenyl moiety has a number average molecular weight of at least about 1800, and a molecular weight distribution (M /M ) of from about 1.5 to about 2.0.

Dispersants and lubricating oil compositions containing same

A boron-containing dispersant composition containing one or more dispersants that are the reaction product of a polyalkenyl-substituted mono- or dicarboxylic acid, anhydride or ester; and a polyamine, in which at least one of the dispersants has a polyalkenyl moiety with a number average molecular weight of at least about 1800, and from greater than about 1.3 to about 1.7 mono- or di-carboxylic acid producing moieties per polyalkenyl moiety; and in which a ratio of wt. % of boron to wt. % of nitrogen (B/N) for the dispersant composition is from about 0.05 to about 0.24.

Soot induced kinematic viscosity increase of lubricating oil compositions for heavy duty diesel engines equipped with EGR systems operating in a condensing mode can be ameliorated by selection of viscosity modifier, lubricating oil flow improvers, detergents and dispersants.

EGR equipped diesel engines and lubricating oil compositions

The residual chlorine content of a polyolefin-substituted carboxylic acylating agent formed by a chlorine-assisted reaction of a polyolefin and an &agr;,&bgr;-unsaturated carboxylic reactant can be reduced by heating the polyolefin-substituted carboxylic acylating agent having a residual chlorine content in the presence of an &agr;,&bgr;-unsaturated carboxylic reactant, optionally in the further presence of a sulfonic acid. Residual chlorine content can be further reduced by using, in the reaction of the polyolefin &agr;,&bgr;-unsaturated carboxylic reactant, a high speed mixer provided with a dual pitch blade.

Polyalkene-substituted carboxylic acid compositions having reduced chlorine content

Low molecular weight Mannich base condensates of hydroxy aromatic compounds, an aldehyde; and an amine, wherein the combined number of substituent carbon atoms does not exceed 80. Such compounds are useful as soot dispersants in lubricating oils when used alone, or in combination with high molecular weight dispersants.

Hydroxy aromatic mannich base condensation products and the use thereof as soot dispersants in lubricating oil compositions

A lubricating oil composition which exhibits improved fuel economy and fuel economy retention which contains keto-amide and keto-ester friction modifiers formed by reaction or trans-esterification of alkyl acetoacetates. The trans-esterified products are also novel compositions of matter.

Friction modifiers for engine oil composition

The present invention provides functional fluid compositions containing a major portion of oil of lubricating viscosity and a novel and synergistic combination of an acylated nitrogen-containing compound having an olefinic substituent averaging in carbon number from 20 to 60 and at least one ashless detergent/dispersant.

Synergistic combinations for use in functional fluid compositions

The present invention relates to a catalyst composition, its methods of preparation and its use in aromatic alkylation processes. The composition comprises a heteropoly compound selected from the group consisting of heteropoly salts and heteropolyacid salts deposited in the interior of a porous support selected from the group consisting of silica, titania, and zirconia, wherein said salt of said heteropoly salt and said heteropolyacid salt is selected from the group consisting of ammonium, cesium, potassium, and rubidium salts and mixtures thereof, and wherein said heteropoly salt and said heteropolyacid salt are formed with a heteropolyacid selected from the group consisting of 12-tungstophosphoric, 12-tungstosilicic, 12-molybdophosphoric, and 12-molybdosilicic acid.
