基于离子液体体系制备纤维素水凝胶

Preparation of Cellulose Hydrogel Based on Ionic Liquid System

以离子液体1-丁基-3-甲基咪唑硫酸氢盐[Bmim][HSO4]催化剂的溶剂体系处理玉米秸秆并制备纤维素水凝胶。对玉米秸秆进行组分含量测定,测试纤维素水凝胶的溶胀度,研究不同种类纤维素对水凝胶溶胀性能的影响。基于酸性离子液体催化1,4-丁二醇/水醇体系制备纤维素水凝胶为生物质多组分利用及纤维素高值化利用提供新的思路。

Corn stalk was treated with solvent system which takes ionic liquid l-butyl-3-methylimidazolium bisulfate[Bmim][HSO4J as catalyst and cellulose hydrogel was prepared.This paper measured the component content of com straw and tested the swelling degree of cellulose hydrogel,studying the effect of different kinds of cellulose on the swelling performance of hydrogel Based on acidic ionic liquid catalyzing 1,4-butanediol/water alcohol system to prepare cellulose hydrogels,which provided new ideas for multi-component utilization of biomass and high-value utilization of cellulose.
