    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: This invention is directed to lubricating oil and functional fluid compositions having improved high temperature stability and which contain at least one phosphorus-containing composition and at least one oil-soluble nitrogen-containing composition. More particularly, the lubricating and functional fluid compositions of the present invention comprise (A) a major amount of an oil of lubricating viscosity, and a minor amount of (B-1) at least one soluble tertiary aliphatic primary amine salt of a substituted phosphoric acid composition characterized by the formula (I) wherein R1 is hydrogen or a hydrocarbyl group, R2 is a hydrocarbyl group, and both X groups are either O or S, and (C) at least one soluble 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. Preferably, the amine salts of the phosphoric acids utilized in the lubricating compositions of the present invention are derived from primary amines, and the soluble nitrogen-containing compositions (C) also contain boron. The lubricating compositions of the present invention are particularly useful in gear applications requiring high thermal stability such as from about 160 DEG C. with intermittent operation up to about 200 DEG C.
