本文采用一种新方法制备 10 0 %脱乙酰度的壳聚糖。低脱乙酰度壳聚糖溶解在酸溶液中并通过溶剂蒸发制备得到片状壳聚糖。片状壳聚糖进行一步碱处理就可以得到高脱乙酰度壳聚糖。
In this paper, a new method for the preparation of 100% deacetylated chitosan. Chitosan with low degree of deacetylation is dissolved in acid solution and prepared into chitosan by evaporation of solvent. One-step alkaline treatment of chitosan can obtain high degree of deacetylation of chitosan.
