【Abstract】 Alkyl phosphates and its ammoniums have been widely used in engine oil. To modify and improve their properties, several phosphonic additives by esterification and amidation were synthesized. And the mechanism and effect of detergent dispersant also were studied . The result shows that polyepoxypropane phosphate amide possesses excellent detergent and reaches advanced level in the world.更多还原
