摘要(Abstract):

离子液体以其熔点低、蒸气压小、酸性可调及良好的溶解性能、黏度、密度等优异的理化特性成为纤维素的新型溶剂。离子液体与传统的纤维素溶剂相比,具有低挥发性、可回收利用、热性质稳定的优点,避免了有机溶剂所造成的污染。介绍了纤维素在离子液体溶剂体系中的溶解、再生和衍生的研究进展。
Ionic liquid is new developed solvent system for dissolving cellulose. Ionic liquid has intrinsically useful properties, such as thermal stability, lower melting point, negligible vapour pressure, acidity changeable and highly solvating, low viscosity and density. Ionic liquid is nonvolatile, nonflammable and recycled solvent. This nonvolatile nature suggests that ionic liquid might potentially be the "green solvents", alternatives to the conventional volatile organic solvents. Recent developments of the ionic liquid to cellulose dissolved, regenerated and homogeneous reaction are reviewed in this paper.
