英文摘要：

Glucose pentaacetate was synthesized at a solvent-free condition from glucose and acetic anhydride with potassium bisulfate used as the catalyst under microwave irradiation. The effects of microwave-irradiation power, microwave-irradiation time, reactants ratio, and amount of catalyst on the yield of glucose pentaacetate were studied. The results showed that the optimum reaction conditions were as follows： the microwave-irradiation power was 462 W, the reaction time was 8.0 min, the molar ratio of glucose and acetic anhydride was 1 ： 7, and the amount of potassium bisulfate was 2.0% ,with the yield reaching up to 89.5%.
