纤维素是当今世界上分布最广、最丰富的生物质。由于纤维素难溶解,导致其利用率仅有7%。目前,离子液体作为溶解纤维素的溶剂为纤维素的有效溶解提供了一个崭新的平台,拓展了纤维素应用领域的前景。主要综述了离子液体溶解纤维素的应用研究进展。归纳了咪唑盐、吡啶盐和新型氨基酸胆碱三种类型离子液体对纤维素物质的溶解研究现状;最后,对该领域的研究进行了展望。
Cellulose is the most widely distributed and abundant biomass in the world.Because cellulose is difficult to dissolve,its utilization rate is only 7%.At present,ionic liquid as solvent for cellulose dissolution provide a new platform for the effective dissolution of cellulose,which broadens the prospect for cellulose application.The advance in the application of ionic liquid for cellulose dissolution were reviewed.In the application study,research status of cellulose matter dissolved by three types of ionic liquids including the imidazolium salt,the pyridinium salt and new type of amino acid choline was summarized.Finally,the research of this field was forecasted.
