【Abstract】 The synthesis process of mono polyisobutylene succinimide ashless dispersant by using accelerating agent was described in this paper. Many reaction factors such as reactant ratio, reaction time and storange, which affect the product quality and application performance, were also studied and tested. Furthermore, the suitability of the synthesis process to the raw materials such as polyethylene polyamine, succinic anhydride and the synthesis process without solvents and accelerating agents were studied. The comparison of synthesis process with accelerating agent has proved to be more reliable. Thus, laboratory products in high quality can be obtained. Both the physical and the chemical properties, and the dispersity under low temperature are similar to those of OLOA-1200 produced abroad.更多还原
