Abstract:
     This invention refers to a ash-free, wear-resistant organic additive of P-N type, not containing surfur. It is the organic reaction mixture of aryl phosphates, long chain amines, polyhydroxy fatty acid ester or polydbasic acid-fatty alcohol ester and benzotriazole. The wear-resistant lubricating oil thus prepared shows high emulsification-resistant ability, high hydrolysis, resistant property non-corrosivity to copper and silver, and good wear-resistant ability.
