| Abstract: | CMC was synthesized under microwave irradiation using waste cotton as raw materials.The optimal conditions for the reaction were determined as: the weight ratio of cellulose to sodium hydroxide to chloroacetic acid was 1.0∶1.1∶1.2,and the cellulose was alkalified for 2 min and etherified for 2 min under microwave irradiation power of 200 W in 95% ethanol.The white powder of product was eventually obtained,with the degree of substitution of 0.75. |
