【Abstract】 The ethylene glycol diacetate was synthesized rapidly by reaction of ethylene glycol with acetic acid in presence of FeCl 3 catalyst and azeotropic agent which can be butyl acetate.The results showed that the mloar ratio of glycol and acetic acid is 1∶1.5,the dosage of butyl acetate is 20%,based on the total weight of reactants and the amount of catalyst used is 0.8%,based on the total weight of reactants. The yield of ethylene glycol moboacetate was 78%.更多还原
