| 摘 要： | 采用甲磺酸作为溶剂兼作氨基保护试剂,对壳聚糖上的羟基选择性酯化,再游离出氨基并对其氯乙酰化,最后进行吡啶成盐,得到新型水溶性的壳聚糖季铵盐衍生物,产物的结构通过核磁共振氢谱和红外光谱进行了表征,从而为壳聚糖季铵盐衍生物的制备提供了一种新途径。

| Abstract: | A novel quaternary chitosan derivative was prepared by selective esterification of hydroxyl groups of chitosan by using methane sulfonic acid as solvent and protection reagent of amino group,followed by liberating amino group and chloroacylation,and finally quaternization with pyridine.While the chitosan derivative structures were characterized with 1H NMR and FT-IR,a novel approach to quaternary chitosan derivatives was provided. |
