    摘要： A process for the preparation of multi-functional additive, amino di(alkylcyclohexyl) phosphorodithioate, for use as an additive in a lubricant composition so as to impart improved coefficient of friction, wear reduction, antioxidant and extreme pressure properties, including the steps of (a) hydrogenating distilled technical cashew nut shell liquid with palladium or nickel or platinum catalyst; to fully hydrogenate the olefinic chain and aromatic ring of the precursor; (b) reacting fully hydrogenated technical cashew nut shell liquid with phosphorus pentasulfide to obtain unpolymerized hydrogenated cashew nut shell liquid phosphorodithioic acid, the reaction being carried out at a temperature ranging from 20 to 140° C. ; and (c) condensing the unpolymerized fully saturated cashew nut shell liquid phosphorodithioic acid with at least one amine to obtain the amino di(alkylcyclohexyl) phosphorodithioate. A lubricant containing a major proportion of a material selected from the group consisting of an oil of lubricating viscosity and a grease; and remainder an additive including amino di(alkylcyclohexyl)phosphorodithioate prepared by the foregoing process.
