Polyisobutenylsuccinimides as detergents and dispersants in fuel: infrared spectroscopy application, L.O: Alemán-Vázquez and J.R. Villagómez-Ibarra, Fuel 80 (2001) 965-968


Abstract


Polyalkenylsuccinimides are synthesized and their detergency and dispersancy properties evaluated in an internal combustion engine. The synthesis is based on the reaction of polyisobutene with maleic anhydride as the first step. The polyisobutenylsuccinic anhydride obtained reacts with primary amines in the last step to give polyalkenylsuccinimides. The results of the evaluations showed that some polyisobutenylsuccinimides reduce the deposit formation in the intake system with good efficiency. Infrared spectra of the prepared compounds allowed their identification.
