Abstract: Gasoline detergent is mainly compounded with polyisobutene amine as the main agent. It is added to gasoline to inhibit and remove sediments that deposited in engine fuel air intake system, so as to improve gasoline combustion system, reduce emissions of carbon monoxide, hydrocarbons and other harmful substances in the tail gas of vehicles, and improve fuel economy. The synthesis process of polyisobutene amine and the compound technology for gasoline detergent are the proprietary technology researched and developed independently by CNPC Jilin Petrochemical Company. In this paper, the synthesis process of polyisobutene amine, and the compound technology and acting mechanisms of gasoline detergent are introduced. The product has good detergency for air intake system and eliminates the deposits in combustion chamber. The quality has reached the international level of similar products, which fills the gaps of production of base agent for gasoline detergents in China, and it is not necessary to import all the main agents.
