ABSTRACT:
A fuel additive is the reaction product of an intermediate reaction product of a hydrocarbon-substituted succinic anhydride and an aminosalicylic acid, preferably a 4-aminosalicylic acid. The intermediate is reacted with an aldehyde, preferably formaldehyde and an alkylenepolyamine preferably tetraethylenepentamine. The reaction product is post reacted with a hydrocarbon-substituted succinic anhydride which can be the same or different as the hydrocarbon-substituted succinic anhydride of the intermediate. The additive has dispersant and detergent properties and is effective in liquid hydrocarbon or liquid oxygenated fuels or mixtures of the said fuels.
