摘要
壳聚糖[β-1→4）-2-氨基-2脱氧-D-葡萄糖]是目前发现的生物界唯一存在的碱性氨基多糖，具有无毒、可生物降解、良好的成膜性和生物相容性，近年来已在水处理、医药、食品、化妆品、农业等领域显示了其独特的应用用价值。但壳聚糖只溶于酸，在很大程度上限制了它的推广应用。
Clycolchitosan was synthesized by reaction of chitosan and ethylene oxide at 60℃ under pH 12～14,following precipitation by ethanol,dialysis and freeze-drying.The structure was confirmed by infrared spectra(IR),()~1H-NMR and X-ray diffraction.The product glycolchitosan was soluble in water in and pH condition as long as pH≤7.Its solubility was above 0.05g/mL in water,pH of the solution was 7.
