| Abstract: | Tributyl citrate esters are synthesized under ultrasonic irradiation by using aluminum sulfate as catalyst. 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%. |
