Title:
BORATED AMINE SALTS OF MONOTHIOPHOSPHORIC ACIDS
Document Type and Number:
WIPO Patent Application WO1988001272
Kind Code:
A3
Abstract:
This invention is directed to borated amine salts of dihydrocarbyl monothiophosphoric acids, and to lubricating and functional fluid compositions containing said borated amine salts. The lubricating and functional fluid compositions have improved extreme pressure properties and high temperature stability. The borated amine salts of the invention may be characterized by the formula (I) (II) (III) or mixtures thereof wherein R1 and R2 are each independently hydrocarbyl groups containing from 1 to about 30 carbon atoms. In one preferred embodiment, the amine salts are derived from hydroxyhydrocarbyl amines. The lubricating and functional fluid compositions may contain, in addition to the borated amine salts, at least one nitrogen-containing composition prepared by the reaction of a hydrocarbon-substituted succinic acid-producing compound with at least about one-half equivalent, per equivalent of acid-producing compound, of an amine containing at least one hydrogen attached to a nitrogen atom. The lubricating compositions of the present invention are particularly useful as lubricating oils, functional fluids and greases.
