Tributyl citrate esters are synthesized under ultrasonic irradiation by using aluminum sulfate as cat-alyst. The Ultrasonic enhancement and the ratio of citric acid to butanol are investigated on esterification yield. The optimum reaction parameters are determined as follows:citric acid to butanol molar ratio of 1 ∶ 4,catalyst amount of 4% citric acid mass,the ultrasonic oscillation temperature of 0 ℃,the oscillation time for 20 min, under which the esterification yield is above 92 . 6%.
