PREPARATION OF A MOLYBDENUM IMIDE ADDITIVE COMPOSITION AND LUBRICATING OIL COMPOSITIONS CONTAINING SAME

摘要

The invention is directed to oil soluble additive compositions, lubricating oil compositions, and additive concentrates. The oil soluble additive composition comprises a salt or complex of (i) a molybdenum component which comprises a molybdenum oxide, sulfide, or oxysulfide of the general formula MoOxSy wherein x≧0, y≧0, and 12≧(x+y)≧2; and (ii) an imide wherein said imide comprises the reaction product of at least one dicarboxylic acid component having from about 8 to about 22 carbon atoms, and at least one nitrogen compound selected from ammonia and a polyamine.
