Abstract
The synthesis of butyl acetate from acetic acid and n-butanol over HZSM-5 catalyst under the condition of microwave irradiation has been studied. The effects of amount of catalyst, microwave power, radiation time and amount of water absorbent were investigated. Under the suitable conditions, i.e., the volume ratio of acetic acid to n-butanol of 1.6, the amount of HZSM-5 of 0.094 g/mL (calculated based on acetic acid), the microwave irradiation power of 640 W, the microwave irradiation time of 30 min and the amount of calcium chloride of 0.375 g/mL (calculated based on acetic acid), the yield of butyl acetate could reach 98.7%.
