| Abstract: | Carboxymethyl Chitosan (CMC) is prepared under microwave irradiation in water solution. The effects of reaction conditions on the degree of carboxymethylation were discussed. The optimum reaction conditions are as follows: the mass ratio of chitosan: sodium hydroxide: chloro-acetic acid is 1 : 10 : 8; the basification time is 2.5h; the carboxymethylation time and the temperature under microwave is 20min and 100℃,respectively. |
