    摘要: A process for the preparation of amino di(alkylaryl) 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) reacting a starting material selected from the group consisting of distilled cashew nut shell liquid and distilled hydrogenated cashew nut shell liquid with phosphorus pentasulfide to obtain unpolymerized cashew nut shell liquid phosphorodithioic acid, the reacting being carried out at a temperature ranging from 40 to 80.degree. C. when the starting material is distilled cashew nut shell liquid and at a temperature ranging up to 140.degree. C. and above when the starting material is distilled hydrogenated cashew nut shell liquid; and(b) condensing the unpolymerized cashew nut shell liquid phosphorodithioic acid with at least one amine to obtain the amino di(alkylaryl) 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(alkylaryl)phosphorodithioate prepared by the foregoing process.

    摘要: Magnesium borate overbased metallic detergent having magnesium borate uniformally dispersed in an extremely fine particle size is prepared by using magnesium alkoxide and boric acid. The process for preparation involves reacting neutral sulphonate of an alkaline earth metal with magnesium alkoxide and boric acid under anhydrous conditions in the presence of a dilution solvent followed by distillation to remove alcohol and part of dilution solvent therefrom. The borated mixture is then cooled, filtered to recover magnesium borated metal detergent. The magnesium borated metal detergent exhibited excellent cleaning and dispersing performance, very good hydrolytic and oxidation stability, good extreme pressure and antiwear properties. Such a detergent can advantageously be used in a hydrocarbon composition.
