Alphaphoshato amide compounds and lubricant and hydrocarbon fuel compositions containing them.

摘要

Alpha-phosphato amides useful as antiwear additives for lubricants and liquid hydrocarbon fuels are disclosed. Alpha-dithiophosphato amides and alpha-thiophosphato amides containing sulfur at the alpha position are also useful as extreme pressure additives. Non-sulfur containing alpha phosphato amides and alpha-thiophosphato amides containing oxygen at the alpha position are also useful as friction-reducing additives. The compounds are non-corrosive and effective at relatively low concentrations when compared with common phosphorus-based additives.
