| 摘 要： | 淀粉是一种多羟基有机高分子化合物.利用相似相溶原理,以甲醇或乙醇为溶剂,溶解淀粉,制成的钠羧甲基淀粉不溶于乙醇,有利于生成物的分离提纯;同时一氯乙酸在醇溶液中的电离度低,对反应的影响较小,有利于反应的进行.此方法具有合成工艺简单,生产效率高,成本低等特点.

| Abstract: | Starch is an organic high polymer chemical compound with many hydroxyls.Based on the principle of "the more similar,the more easy to solution",with methyl alcohol or ethyl alcohol as solvent,solution the starch,the made-up CMS is not solvent in the ethyl alcohol,this is favorable for the separation and purification;At the same time,the ionization degree of the chloroethanoic acid in the solution of ethyl alcohol is small,so the influence on the reaction is small,this is good for the reaction.This method possesses simple synthesizing technology,high producing efficiency and low cost. |
