木质素在离子液体中溶解及改性的研究进展

摘要

木质素是自然界中含量仅次于纤维素、唯一含有苯环结构的可再生生物质资源，对其进行有效的开发利用具有较高的经济价值和社会价值。离子液体作为一种新型绿色溶剂，在木质纤维素溶解方面展现了良好性能，本文粗略地概述了木质素的基本结构和性质，对木质素在离子液体中的溶解及改性等方面的研究进行了总结和综述，并在离子液体在木质素溶解降解方面应用研究的发展前景进行了分析讨论。%As the material only secondly abundant to cellulose in the nature, lignin is the only renewable biomass resources containing benzene ring structure. It has not only high economic value but also the social value to carry on the effective exploitation. Ionic liquids, as a new type of green solvents, show a good performance in the dissolution of lignocellulose. The basic structure and properties of lignin were shortly outlined, the performance of structure change of lignin after dissolved in ionic liquids were reviewed, and the development research prospects of application of ionic liquids in the dissolution and depolymerization lignin were discussed.
