摘要
以壳聚糖为原料,通过醚化后制得水溶性较好的羧甲基壳聚糖。实验确定的制备羧甲基壳聚糖的最适宜条件为v(异丙醇)∶m(壳聚糖)为10∶1,m(氯乙酸)∶m(壳聚糖)为1.2∶1,反应温度70℃,反应时间2h,碱化时间为1h。
Based on chitosan, carhoxymethylchitosan with better water solubility is synthesized via etherification reaction. Experimental results show that the suitable conditions arc as follows: v(isopropanol) : m (chitosan) = 10: 1, m ( chloroacetic acid) : m(chitosan) -- 1.2: 1, the reaction temperature is 70℃, the reaction time 2h, and the hasifying time 1h.
