A composition obtained by reacting an O,O'-dialkyldithiophosphoric acid with a hydroxyalkyl acrylate or a hydroxyalkyl methacrylate, and reacting the product thereof with a dialkylphosphite provides good antiwear protection.

Nitrogen-free phosphorus compounds and lubricants containing the same

A lubricant composition of an oil of lubricating viscosity and a phosphite ester reaction product of a monomeric phosphorous acid or an ester thereof with a first alkylene diol having two hydroxy groups in a 1,4 or 1,5 or 1,6 relationship and a second, alkyl-substituted, diol being a substituted 1,3-propylene diol, exhibits good wear and frictional performance.

Mixed phosphorus esters for lubricant applications

Polyalkylene substituted carboxylic acylating agents which contain chlorine are synthesized by chlorine induced condensation of polyalkylenes and .alpha.-.beta. unsaturated carboxylic groups are treated with sulfur to reduce chlorine content of the carboxylic acylating agent.

Low chlorine polyalkylene substituted carboxylic acylating agent

The present invention is directed to a composition made by reacting A) an aldehyde of 1 to 12 carbon atoms or a reactive equivalent thereof; and B) at least one etheramine represented by the formula
