丙二酸衍生物的润滑性

Study on Lubricity of Malonic Acid Derivants

从水溶性润滑添加剂的分子设计观点出发，把可水溶的油性剂丙二酸导入极压剂二烷基二硫代磷酸，合成了Ｏ，Ｏ－二烷基－ｓ－（烷基－ω－二羧酸）二硫代磷酸酯，测试结果表明，这是一类新型的、性能优良的水溶性润滑添加剂．

in accordance with the viewpoint of molecular design for water soluble lubricant additives,water soluble oilness agent malonic acid was introduced into extreme pressure agent O,O-dialkyl-phosphorodithioate,and O,O-dialkyl-s-(alkyl-ω-dicarboxyl acid)-phosphorodithioate was synthesized.Test results show that it is a new water soluble lubricant additive with excellent lubricity.
