Maleic anhydride-polyether-polyamine reaction product and motor fuel composition containing same
A material is described having a use as a motor fuel additive for controlling engine octane requirement increase (ORI), controlling and reducing hydrocarbon and carbon monoxide engine emissions, and having carburetor detergency properties. The material is the reaction product of maleic anhydride, a polyether polyamine, preferably a polyether diamine, and a hydrocarbyl polyamine, preferably an n-alkyl-alkylene diamine. A concentrate comprising the prescribed reaction product dissolved in a hydrocarbon solvent is also described. Motor fuels containing the reaction product additive of the instant invention show improved ORI control and carburetor detergency in comparison with motor fuels without the reaction product additive.
