| Abstract: | The modified characteristics with the modifier of chloroacetic acid by the method of single factor and orthogonal were studied in this paper. The optimum condition of modifier showed that the modification of isopropyl alcohol is 10mL;the dosage of chloroacetic acid is 1.0 mL;the reaction temperature is 70 ℃;reaction time is 2 h. And the degree of substitution of carboxy methyl chitosan is 0.88%. |
