An extreme-pressure lubricating composition comprises a lubricating oil having a viscosity between 30 and 55 S.U.S. at 210 DEG F., 0.5-6 per cent by weight of pentachlorphenol and 0.5-10 per cent by weight of an oil-soluble trialkyl, triaryl, dialkyl monoaryl, or monoalkyl diaryl phosphate or phosphite. Suitable phosphates or phosphites are tributyl, triphenyl, tricresyl, dicresyl monobutyl and monophenyl dibutyl phosphates or phosphites. The composition may contain additional ingredients such as corrosion inhibitors, detergents and antioxidants. In the examples, mineral lubricating oil compositions are described containing pentachlorphenol and tributyl or tricresyl phosphate. For comparison purposes, mineral lubricating oil compositions are described containing (a) phosphosulphurized bright stock, (b) chlorinated camphene, (c) a mixture of chlorinated paraffin wax and dibenzyl disulphide or (d) pentachlorphenol.
Water soluble lubricant compositions comprising alkanolamine and organic acid are improved by employing as the organic acid a partial acid amide of a dicarboxylic acid, such as mono-PRIMENE 81 R amide of succinic acid, mono-di-2-ethylhexylamide of maleic acid, mono-di-2-ethylhexylamide of methyltetrahydrophthalic acid and mono-di-2-ethylhexylamide of methylhexahydrophthalic acid as the organic acid.

[Also in Divisions C4-C5] Novel spiroheterooyclic pentaco-ordinate silicon compounds of the formula wherein R represents -CF 3 or a C 1-6 hydrocarbon radical free of aliphatic unsaturation, Z represents a C 1-6 hydrocarbon radical free of aliphatic unsaturation or a -CH 2 CH 2 A radical in which A is a C 1-4 perfluoroalkyl radical, and R1 and Y represent hydrogen or methyl radicals, are prepared by reacting a heterocyolic silane of the formula in which X represents an alkoxy radical, with an alkanolamine of the formula in the presence of a suitable solvent. The coordinate link may be broken with carbon tetrachloride to give a corresponding tetravalent silicon compound. The psntaco-ordinate products may be used as corrosion inhibitors and antioxidants for lubricating oils and greases. Phenyl - (tetramethylethylenedioxy) methoxysilane is prepared by heating phenyl trimethoxysilane with pinacol in presence of sodium methoxide.
The present invention is directed to methods of producing reduced viscosity oleaginous compositions containing Group I-B, II-A and II-B metal, particularly copper and/or zinc, salts of the product of a polyolefin having a number average molecular weight (Mn) of at least 600 which has been substituted with at least one dicarboxylic acid producing moiety per polyolefin molecule, wherein the metal salt product is contacted with lower aliphatic or cycloaliphatic amines having from 1 to 4 nitrogen atoms per molecule. The compositions of the present invention can also provide increased stability to viscosity growth, e.g. during storage of the materials prepared by the process of this invention. The resulting solutions are useful in lubricating oils as additives, e.g., as antioxidant lube oil additives.
A surfactant is synthesized from an amine or an alcohol and a hydrocarbyl-substituted succinic acylating agent by feeding the amine or alcohol into a stream comprising the hydrocarbyl substituted succinic acylating agent, to form a combined stream; passing the combined stream through an in-line mixer so as to effect premixing and initial reaction of the components; and thereafter passing the combined stream into a reactor, where the combined stream is further processed to form the surfactant.

The invention herein is concerned with new compositions of matter made by (1) reacting phosphorus pentasulfide with an amide and (2) reacting this product with a nitrogen-containing compound, and lubricant compositions containing same. The compositions reduce friction to a greater extent than lubricants containing no additive and, when placed in lubricating oils and used in an internal combustion engine, fuel consumption is reduced.
Using a novel process of one or more combined steps, modified novel block copolymers are prepared by alkylating or hydrogenating a block copolymer precursor containing at least two segments, in which segment A consists of a styrene polymer, either styrene alone or a hydrogenated random butadiene-styrene copolymer and from 1% to about 50% by weight of segment B being an alkylene oxide or sulfide copolymerized with the first segment as an AB or BAB copolymer. These novel copolymers perform as multifunctional additives in industrial organic compositions, both hydrocarbon fluids, such as petroleum-derived, and non-hydrocarbon, or synthetic fluids, providing such utility as detergency, emulsification and viscosity index improvement. These copolymers have molecular weights in the range of from about 1,000 to 500,000. The copolymers are particularly useful in lubricating oils, greases and fuels, especially cross-graded lubricants, crude oils, diesel oils, gasoline and fuel oils. Copolymers capped with metal diisocyanate have excellent thermal and oxidative stability.
