摘　　要：纤维素是自然界中储量最大的天然高分子,具有可再生、可完全生物降解、生物相容性好等诸多优点,被认为是未来能源、化工的主要原料。由于聚集态结构的特点,天然纤维素不熔融、难溶解,使其应用受到极大限制。近年来,人们发现一定结构的离子液体可以高效地溶解纤维素,这为纤维素的加工与功能化提供了一个崭新和多用途的平台。以离子液体为介质,通过溶解再生和均相衍生化反应可以制得一系列纤维素基高分子材料;通过催化分解等方法,可以得到不同类型的生物质能源以及平台化合物等,从而极大地拓展了纤维素资源的应用领域,促进了纤维素科学的发展。本文收集整理了近十年间发表在国内外期刊上的相关文献,综述了关于离子液体在纤维素化学中应用研究的最新进展。As the most abundant natural polymer on the earth, cellulose has many attractive properties such as renewability, biodegradability, biocompatibility, and broad chemical-modifying capacity. Cellulose has been considered as the sustainable raw material of energy and chemical engineering in the future. However, because of the well-developed intra- and intermolecular hydrogen bonding network,cellulose is unmeltable and insoluble in water or conventional organic solvents,which limits its wide utilization. More recently, it is found that certain ionic liquids （ILs） have excellent dissolving capability for cellulose,which provids a new and versatile platform for cellulose processing and derivatization. A series of biopolymer-based materials, biomass energy, platform chemicals, and so on,have been produced with the aid of ILs. Based on about 210 relevant papers published during the past 10 years, this review article highlights recent progress in the field of dissolution, regeneration, derivatization, extraction and conversion of cellulose with ILs. In additon, a perspective on ILs application in cellulose chemistry in the future is briefly discussed. It is hoped that this review work will stimulate research and collaborations that will lead to significant progress in this area.
