Synthesis and characterization of polyisobutylene-amine from polyisobutylene and tetraethylenepentamine and its performance as deposit control additive in one cylinder gasoline engine

摘要

Fuel is still a crucial commodity in this world. Fuel can be utilized in various economic activities, such as on vehicle. The utilization of fuel in vehicle often produce deposit and pollution that came from imperfect combustion. One alternate solution to improve fuel combustion efficiency and reduce pollution is by formulating fuel additive that can control deposit in vehicle combustion chamber. Deposit Control Additive (DCA) consists of polar head and hydrocarbon tail as a non-polar end has a similarity of structure with surfactant. One of the results of amination reaction which is Polyisobutylene (PIB) - amine has proven its ability as DCA. The longer the molecular length of PIB, the higher its effect on improving fuel combustion efficiency. In this study, there are 2 type of PIB being used with molecular weight of 950 and 1300 and 2 type of amine, tetraethylenepentamine and diethylenetriamine. The synthesized result is being tested to acquire its physical-chemical properties and also its performance as DCA in one-cylinder gasoline engine with fuel.
