摘要

离子液体1-乙基-3-甲基咪唑醋酸盐([ EMIM] Ac)可以溶解天然高分子等许多聚合物，尤其对于纤维素具有较强的溶解能力，且溶解过程基本不造成纤维素降解，故可以作为纤维素的有效溶剂，用于纤维素的溶解加工。与其它溶剂相比，[ EMIM] Ac 具有使用安全、不污染环境、易回收循环利用等优势，故在纤维素溶解、纺丝方面具有广阔的应用前景。本文主要介绍了[ EMIM] Ac 的多种制备方法及其优缺点，这对其它醋酸盐类离子液体的制备也具有指导意义;并概述了[ EMIM] Ac 在纤维素溶解、纺丝等方面的应用研究。

Abstract

Ionic liquid 1-ethyl-3-methylimidazolium acetate ([ EMIM] Ac)

which has stronger ability to dissolve cellulose especially

can be used to dissolve natural polymer and many other polymers. As the dissolving process of cellulose causes no degradation

[ EMIM] Ac can be used as an effective solution in dissolving and processing of cellulose. Compared with other solutions

[ EMIM] Ac has many advantages of use safety

no pollution to environment and easy recovery recycling

and has wide application prospect in the dissolving and spinning of cellulose. Various preparation methods of [ EMIM] Ac and their advantages or disadvantages are introduced in this paper

which have a guiding significance to the preparations of other acetic acid salts ionic liquid. And the application research of [ EMIM] Ac in cellulose dissolving and spinning is summarized.
