    摘要: A process for the preparation of CNSL phenoxy carboxylic acid derivatives for use as an additive in a lubricant composition so as to impart improved rust inhibiting properties, including the steps of (a) partially hydrogenating distilled technical cashew nut shell liquid with palladium or nickel or platinum catalyst; to hydrogenate the olefinic chain; (b) reacting cashew nut shell liquid or partially hydrogenated technical cashew nut shell liquid with halogeno carboxylic acid derivatives to obtain unpolymerized cashew nut shell liquid phenoxy carboxylic acid derivatives, the reaction being carried out at a temperature ranging from 20 to 140° C. 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 CNSL phenoxy carboxylic acid derivative prepared by the foregoing process.
