| Abstract: | The ethylene glycol monoacetate could be synthesized rapidly by reaction of ethylene glycol with acetic acid in the presence of FeCl_3 catalyst and azeotropic agent of butyl acetate. As the results shown, the molar ratio of glycol and acetic acid was 2, and based on the total weight of reactants, the dosage of butyl acetate was 15% while the amount of catalyst used was 0.6%, the yield of ethylene glycol monoacetate could achieve 82%. |
