摘要
甲壳素及壳聚糖作为生物大分子材料难溶于诸多溶剂,从而限制了其应用和修饰改性。因此,研究与开发良好的溶剂体系具有重要意义。本文首先对甲壳素及壳聚糖在各种离子液体中的溶解性能和溶解机理进行了详细综述,其次概述了甲壳素与壳聚糖在离子液体介质中进行修饰的化学反应研究(如:水解作用、酰基化反应和接枝共聚反应等),最后提出离子液体作为一类可回收循环使用的良好溶解介质将会对甲壳素及壳聚糖的实际应用和修饰改性提供更好的媒介,并拓宽甲壳素及壳聚糖的研究与应用领域。
Chitin and chitosan, as the biological macromolecular materials, are hardly soluble in many traditional solvents. This behavior limits their wide application and chemical modification. Therefore, it will he of great importance to research and develop the better solvent system. In this paper, the dissolution performance and dissolving mechanism of chitin or chitosan in ionic liquids are reviewed in the first place. Secondly, the chemical modifications of chitin or ehitosan in ionic liquids （such as hydrolysis, acylation, graft copolymerization and so on） are summarized. Ionic liquid, as a kind of the recycled fine solvent, will provide a better media for the effective application and chemical modification of chitin or ehitosan. Based on the ionic liquid solvent, the research and application of chitin or chitosan will be broaden.
