离子液体对纤维素溶解性能的研究进展

摘要

Cellulose is the most abundant natural renewable resources. the development of a prospective, environmentally friendly, biodegradable solvent has become one of the main tasks in recent years. As the nonderivative cellulose solvent, ionic liquids have gained increasingly considerable interest in the research of cellulose. The recent developments concerning the ionic liquids as cellulose solvents are reviewed, which deal with cellulose dissolution and regeneration. The problems in the process of the dissolution are discussed and the mechanism is summarized. The development direction of cellulose dissolution in ionic liquids is put forward.%纤维素是自然界含量最丰富的可再生资源,开发一种具有应用前景、环境友好、生物可降解的新型绿色溶剂成为近年来的一项主要任务.离子液体作为纤维素的非衍生化溶剂,在纤维素研究中呈现出了良好的发展态势.综述了国内外离子液体对纤维素溶解、再生的近期研究成果,分析了纤维素在溶解过程中存在的问题,并探讨了纤维素的溶解机理,提出了离子液体溶解纤维素的发展方向.
