Using sodium bifulfate as catalyst,tristyrylphenol polyoxyethylene ether and oleic acid were es-terified to synthesize tristyrylphenol polyoxyethylene ether oleate. Effects of factors,such as molar ratio of oleic acid to ether,the dosage of catalyst,reaction temperature,reaction time on the results of esterification were investigated. The result showed that the optimal conditions were as follows:n( oleic acid)∶n( ether)=0. 99∶1,the dosage of the catalyst 0. 50% of total mass of the reactants,reaction time 5 h and reaction temperature 150 ℃. Under this condition,the yield of esterification reached more than 98%.
