摘要
有机磷酸酯(盐)具有极压抗磨,抗氧化和防锈等作用,是内燃机油和齿轮油中不可缺少的添加剂,本文根据^(31)P NMR化学位移判断润滑油中各种磷酸酯的方法,在归纳了已见报道的有机磷酸酯(盐)的^(31)P NMR化学位移的基础上,对市售内燃机油和齿轮油中的含磷化合物结构作了初步分类。
Organophosphates have properties of extreme pressure, antiwear, antioxidation and an-tirust. They are indispensable additives for internal-combustion engine oil and gear oil. In this paper, it was reported that the structures of phosphorus-containing compounds in engine oil and gear oil on the market had been classified preliminarily according to the chemical shifts of P-31 NMR spectra of Organophosphates reported.
