摘　　要：生物质是自然界储量丰富且可再生的资源,其中植物纤维最丰富。木质素作为植物纤维的主要成分之一,是含有苯环的天然大分子,具有高附加值利用的潜力。文章综述了低共熔溶剂(DES)用于木质素分离的有关研究,介绍了DES的组成和性质,讨论了DES分离木质素的机理,探讨了辅助手段如微波、超声、蒸汽爆破对DES提取木质素效果的影响,以及DES的回收与利用问题,为DES分离木质素的研究提供了参考。Biomass is an abundant and renewable resource in nature,with Wood Fiber being the most abundant.Lignin,as one of the main components of plant fibers,is a naturally occurring macromolecule containing benzene rings and has the potential for high added value utilization.This paper reviews the relevant research on the use of deep eutectic solvents(DES)for lignin separation,introduces the composition and properties of DES,discusses the mechanism of lignin separation by DES,explores the impact of auxiliary methods such as microwave,ultrasound,and steam explosion on the efficiency of lignin extraction by DES,as well as the recovery and utilization of DES,providing a reference for the research on DES-based lignin separation.
