| Abstract: | The optimum conditions for preparation of carboxymethyl cellulose with water medium method in laboratory and industry are: matter ratio of raw materials cotton fiber∶ ClCH 2COOH∶30%NaOH=5∶6∶26, reaction about 2 h at normal temperature and atmospheric pressure. The substitution rate of the carboxymethyl cellulose is as high as 0.8～2.2, its viscosity is as high as 1 Pa·s～3 Pa·s and it dissolves quickly and well. |
