Abstract: The present invention is one kind of gasoline additives. The compounds consist of tertiary amine, amide and poly(oxybutylene) backbone in the same molecule. The process of making this type of products required an initiator containing primary amine and tertiary amine as the starting diamines. The primary amine will be converted into amide, while the tertiary amine remained intact. Then the amide is converted into butoxylates through butoxylation at CON—H position. The preparation therefore involved two steps: (1) amidation of diamines containing primary/tertiary amines with ethyl acetate to form amidoamines, and (2) butoxylation of this amidoamines to poly(oxybutylene)amidoamine. The product is gasoline soluble and can be used as additive having good performance of detergency and octane requirement reduction.
