Fuel compositions containing alkyl-substituted cyclic urea-substituted amines

摘要

A fuel composition comprising a major amount of hydrocarbons boiling in the gasoline or diesel range and an effective detergent amount of an alkyl-substituted, five- or six-membered cyclic urea-substituted monoamine or diamine which is the reaction product of: (a) a halogenated aliphatic hydrocarbon derived from a branched-chain polyolefin having an average molecular weight of about 400 to 5000; (b) a polyamine having from 3 to 4 amine nitrogen atoms and from 4 to 9 carbon atoms; and thereafter (c) urea.
