Lubricating oil composition comprising the reaction product of (a) molybdenum sulfonate, which is the reaction product of a hydrocarbyl sulfonic acid compound and molybdenum halide, and (b) sulfur or a sulfur-yielding compound. Preferably, an alkyl sulfonic acid having from 8-200 carbon atoms in the alkyl group is reacted with molybdenum pentachloride, and the molybdenum sulfonate resulting therefrom is sulfurized to produce the reaction product of the invention.

Molybdenum sulfonates for friction reducing additives

Anti-friction additives for lubricating oil are prepared by reacting a sulfurized organic compound having an active hydrogen or potentially active hydrogen with a molybdenum halide. The resulting product has friction reducing properties at least as good as currently available phosphorus-containing additives.

Molybdenum-containing friction modifying additive for lubricating oils

Lubricating oil composition comprising the reaction product of a phenolic compound, a molybdenum, an amine and sulfur or a sulfur-yielding compound. Preferably, molybdenum oxide, an alkyl-substituted phenol having an alkyl side chain of at least 9 carbon atoms, an amine having at least one aliphatic hydrocarbon-based radical or aliphatic-substituted aromatic radical and elemental sulfur are reacted to produce the reaction product of the invention.

This invention provides a process for the oxidation of copolymers of ethylene and olefinic monomers in the temperature range of from about -40.degree. F to about 800.degree. F. The oxidation is carried out in the presence of about 0.05 weight percent to about 1.0 weight percent based on copolymer/oil solution, of an oil soluble benzene sulfonic acid or salt thereof. These benzene sulfonic acids or salts thereof affect the rate of the oxidation reaction and/or the color of the oxidized product or amine reaction products thereof.
