Abstract

Using p-toluensulphonic acid supported by activated carbon as catalyst,glycerol triacetate was synthesized from glacial acetic acid and glycerin.The optimum conditions of the reaction were determined as following: molar ratio of glycerin to glacial acetic acid is 1∶4;the mass of catalyst to total is 1.8%;esterification time is 4 h;w(p-toluensulphonic acid)is 36%.The results show that the yield is over 92%.
