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.
本发明公开了可用作润滑油和液态烃燃料抗磨添加剂的α-磷酰胺。α-位含硫的α-二硫代磷酸酰胺和α-硫代磷酸酰胺也可用作极压添加剂。不含硫的α-磷酰胺和α-硫代磷酰胺在α位含氧,也可用作减摩添加剂。与常见的磷基添加剂相比,这些化合物无腐蚀性,浓度相对较低时也有效。
