In this study, a novel chitosan derivative, O-acetyl-chitosan acetic ester (ACHA), was directly obtained by esterification of CS with acetic acid in the presence of sulfur dichloride at room temperature.
O-Acetyl-chitosan acetic ester (ACHA), an amphiphilic chitosan derivative, was synthesized by using chitosan (CS) and acetic acid under the catalysis of sulfur dichloride, with the yield of 79.4%.
