| Abstract: | Carboxymethyl Chitosan was synthesized by ultrasonic radiation with chitosan as raw materials,ethanol as dispersant, and chloroacetic acid as ethyloic reagent. The reaction condition was optimized by four factors and three levels orthogonal experiments, which showed that：mNaOH/mCTS is 1.5,mclCHCOOH/mCTS is 1.5,reaction time is 2h, reaction temperature is 60℃ .The product structure was characterized by the infrared spectroscope, ultraviolet-obvious spectrophotometer,the TG/DTA analyzer, the X-ray diffractometer, and the scanning electro, microscope. |
