摘　　要：低共熔溶剂(DES)是一种新兴的绿色溶剂,具有和离子液体类似的物理化学性质,以及易制备、成本低、溶解能力强、可设计性等优点。利用DES溶解和分离木质纤维原料及其组分进而生产生物质能源与材料是一种新型环保的木质纤维原料利用方法。在介绍DES的制备、物理化学性质及溶解机理的基础上,综述了DES溶解纤维素、半纤维素和木质素,以及分离木质纤维组分的研究进展,最后对DES应用于木质纤维领域今后的工作做出了展望。Deep eutectic solvents (DESs), similarly to ionic liquids in physicochemical properties, have distinctive properties of easy synthesis, cost effectiveness, high dissolution power, and structure design ability. Dissolving and separating lignocellulose and its components by deep eutectic solvents is a new and environmentally friendly method to produce biomass energy and materials. Based on the introduction of the physicochemical properties and dissolution mechanism, the development of DESs applications in dissolving and separating cellulose, hemicellulose and lignin was reviewed. Finally, the prospects of the utilization of DESs in the field of lignocellulose were proposed.
