Preparation of Hydroxypropyl Chitosan


Hua LI

In order to solve poor water solubility of chitosan, chitosan was modified by Chydroxyl group. Hydroxypropyl chitosan with good water solubility was prepared by using chitosan as raw material, propylene oxide as etherifying agent and isopropanol as solvent in alkaline environment. The suitable conditions for etherification reaction were determined by single factor experiments. The results showed that the optimum conditions for the synthesis of hydroxypropyl chitosan were as follows: under the alkaline environment of 25
