| 摘 要： | 甲壳素几乎不溶于任何溶剂,由于其脱乙酰化产物壳聚糖含自由氨基,能被酸质子化而溶解,所以壳聚糖的应用领域远多于甲壳素.但是壳聚糖也仅能溶于酸性介质中,并不能溶于纯水和普通有机溶剂,因而人们对甲壳素或壳聚糖进行各种化学改性1,2],寻求溶解性更好尤其能溶于水的衍生物,以扩大其应用范围.本文按文献2～4]方法合成了O-丁酰化壳聚糖(简称丁酸壳聚糖),首次报道它具有溶致液晶性.

| Abstract: | Butyryl chitosan was synthesized and characterized by using FTIR, DSC, WAXD and PLM. Liquid crystallinity of butyryl chitosan was first reported in this paper. Comparing with chitosan, thermal stability and crystallinity of butyryl chitosan decreased but solubility increased, because hydrogen bond interactions between macromolecules were disrupted. |
