摘要： The present invention relates to an alkylphenyl poly(oxyalkylene) polyamine acid ester fuel detergent effective for controlling deposit generated in an automobile engine, prepared by reacting polyamine and alkylphenyl poly(oxyalkylene) maleate derivative prepared by reaction of alkylphenyl poly(oxyalkylene) alcohol and maleic anhydride, through Michael reaction. A fuel detergent diluted solution comprising 5-70 wt % of said fuel detergent and an inert organic solvent, and a hydrocarbon fuel composition comprising thereof are prepared. The present invention does not use deadly toxic phosgene gas used in preparation of a deposit control additive for conventional polyether amine deposit control additive and prevents generation of amine salt to eliminate the process for removing amine salt. The present invention does not use excessive polyamine, minimizing the consuming amount of the polyamine and eliminates the process for removing and recovering the polyamine salt such that it provides a new fuel detergent showing excellent detergency.
