摘要：

A novel process for the preparation of acetates of polysaccharides is described herein. The process involves the acetylation of polysaccharides with acetic anhydride in the presence of iodine as a catalyst. No solvent is required to bring about the acetylation. The method is simple, rapid, and characterized by a high conversion ratio. Conversion of cellulose and starch into their corresponding acetate derivatives has been demonstrated.
