    摘要: Lubricant and fuel compositions containing a small additive concentration of a novel organo-phosphorus composition based on phosphite-derived hydroxyl compounds and amine phosphates possess excellent antiwear properties coupled with good extreme pressure activities. Additional antioxidation, cleanliness, antifatigue, high temperature stabilizing, and friction modifying properties are expected. Both the phosphite-hydroxy moiety and the amine phosphate moiety are believed to provide the basis for the synergistic antiwear and EP property of these novel additives.
