LOW SULFUR METAL DETERGENT-DISPERSANTS

摘要

5 A process for preparing alkylhydroxybenzoate detergent-dispersant additiveshaving low sulfur content and high TBN is described. The alkali metal alkylhydroxylbenzoate, alkaline earth metal alkylhydroxybenzoate and overbased alkaline earth metal alkylhydroxybenzoate reaction products described have a sulfur content in the range of from about 0.1 to 1.2 wt % are effective anti 10 corrosive detergent-dispersant additives in lubricating oil compositions.(no suitable figure)
