【Abstract】 Starch acetate with high DS was prepared by glacial acetic acid and acetic anhydride using methyl sulfonic acid as a catalyst. The influences of reaction temperature, reaction time, ratios of reactants on the esterification have been examined. The product is characterized by chemical analysis, infrared analysis, intrinsic viscosity and solubility measurements. High linear amylose was found easier to be esterized.
