| Abstract: | The carboxymetholcel(CMC)is synthesized using natural cotton cellulose materials pretreated by steam explosion, and the synthetic process is optimized. The effects of pressure of steam explosion pretreatment are studied by determined degree of substitution of CMC. The results indicate that the properties of CMC are improved by increasing the pressure of steam explosion pretreatment in a certain range. |
| Keywords: | carboxymetholcel cotton cellulose modification steam explosion degree of substitution |
