摘要
介绍了壳聚糖经碱处理后,与氯乙酸反应生成O-羧甲基壳聚糖的制备方法,并对其制备条件进行了研究,筛选出了最佳制备条件.结果表明,当壳聚糖与氯乙酸的摩尔比为1∶4、反应时间为8h时,产品产率最高.
This paper introduces the preparation method and the best preparation conditions of O-carboxymethylchitosan from chitosan.The result showed that the yields are the greatest when the molar ratio of chitosan and chloroacetic acid is 1∶4 and the reaction times are 8 hours.
