铜氨溶液法和铜乙二胺溶液法对测定纤维素聚合度结果的影响

摘要

Cellulose can be dissolved with copper ammonia solution and copper ethylene diamine solution , We obtained the degree of polymerization of cellulose by measuring the cellulose-copper ammonia solution viscosity.By analyzing discussed the two solutions system were measured degree of polymerization of the cellulose of different kinds, Compared with copper ammonia solution, A higher degree of polymerization of the cellulose copper ethylene diamine solution measurement.%铜氨溶液和铜乙二胺溶液都可将纤维素溶解，通过测定纤维素-铜氨溶液的黏度可得到纤维素的聚合度。该文通过分析、探讨上述2种溶液体系分别测定不同种类的纤维素聚合度表明，与铜氨溶液相比，铜乙二胺溶液测定纤维素的聚合度更高。
