纤维素在离子液体中的降解研究进展

随着化石能源的日益短缺和环境污染问题的日趋严重,可再生的生物质资源引起了人们的广泛关注。离子液体作为一种新型的绿色溶剂,越来越多的被应用到木质纤维素的溶解和降解中。从无机金属氯盐、酸催化和酶催化三个方面简要介绍了近几年来纤维素在离子液体中的降解转化过程,指出了离子液体自身存在的缺陷和应用过程中存在的问题,提出了未来研究工作的重点和对关键问题的解决方法。

Research on Degradation of Cellulose in Ionic Liquids

As the fossil energy shortages and environmental pollutions has become increasingly serious,the renewable biomass resource has aroused wide concern.Ionic liquids as a new type of green solvent,has been more and more applied in the dissolution and degradation of lignocelluloses.The paper briefly introduces the degradation and conversion processes of cellulose in ionic liquids in recent years catalyzed by inorganic metal chloride,acid catalysis and enzyme catalysis.The article pointes out the defects of ionic liquids and problems in application process.Lastly,the review puts forward that the focus of future research work and the solution to key issues.
