Abstract | Mannich base ashless dispersants were synthesized by the following two steps: the reaction of high active polyisobutylene (PIB) with phenol in the presence of a Lewis acid catalyst to form alkylphenols, then the reaction of alkylphenols with formaldehyde and polyalkenepolyamines to obtain Mannich bases. Gasoline detergent package containing the synthesized Mannich base can decrease CO emission of 20.4% and HC emission of 31.5% respectively in a gasoline engine bench test, and greatly improve the electronic port fuel injector fouling in the simulation test of PFI fuel injector. Diesel fuel multi-functional additives containing modified Mannich base can be used as diesel stabilizers, lubricity additives as well as smoke suppression additives. |
