    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.

    Abstract: Lubricating and functional fluid compositions are described which comprise at least one oil of lubricating viscosity and an extreme-pressure and friction-modifying amount of (A) at least one phosphite ester characterized by the formula (I) wherein R1 is a straight-chain hydrocarbyl group and R2 is a branched-chain hydrocarbyl group. The invention also relates to compositions which comprise the combination of such phosphite esters as represented by Formula I and various sulfur-containing compositions. The compositions comprising said combinations also are useful in lubricating and functional fluid compositions including lubricating oils and greases. Aqueous systems containing the phosphite esters represented by Formula I as well as combinations of phosphite esters with sulfur-containing compositions also are described.
