摘要：
Oil dispersible compounds of organic acids containing Cerium, and oil dispersible overbased salts of organic acids containing Cerium and an alkaline earth metal; the synthesis method of the same and use thereof in lubricating oils as detergent additives, anti-friction additives, extreme-pressure tribological coupling additives and with the aim of improving the quality of diesel engine emissions. In particular, the use of these additives in lubricating oils for diesel engines allows the compounds containing Cerium to be conveyed onto the particulate trap for the treatment of exhaust gases, improving its efficiency.
