摘　　要：从低共熔溶剂的理化性质、低共熔溶剂用于木质素提取的分离依据、影响因素、强化手段及分离局限性等方面综述了低共熔溶剂提取木质素的研究现状,展望了低共熔溶剂在生物质木质素分离提取方面的应用前景。低共熔溶剂的黏度和密度受氢键供体的含量、类型以及反应体系温度等因素影响。降低黏度和密度可以提高溶剂与木质素-碳水化合物之间的传质效率,从而增强木质素的溶出效果。此外,木质素的提取率还与低共熔溶剂中官能团的种类和含量、酸碱性有关。利用低共熔溶剂的可设计性,根据性质参数筛选组成成分,并针对木质素分离体系设计溶剂,可提高木质素的提取率和品质。拓宽木质素来源,开展废弃生物质中木质素的提取研究,有助于实现环境保护和资源利用的双重目标。The research status of lignin extraction using deep eutectic solvents(DES)is reviewed,including the physical and chemical properties of DES,the separation theory of DES for lignin extraction,influencing factors,strengthening methods,and separation limitation.The potential application prospects of DES in the separation and extraction of biomass lignin are also predicted.The viscosity and density of DES are influenced by the factors such as the content and type of hydrogen bond donors,as well as the temperature of reaction system.Reducing the viscosity and density of DES can enhance the mass transfer efficiency between DES and lignin-hydrocarbon compounds,thereby improving the extraction efficiency of lignin.In addition,the extraction efficiency of lignin also has relations to the type and content of functional groups in DES,as well as their acidity or alkalinity.Based on the designable characteristics of DES,the components of DES are screened out according to their property parameters.DES can be specifically tailored for the specific lignin separation system to improve the extraction rate and quality of lignin.Expanding the sources of lignin and developing extraction research of lignin from waste biomass will contribute to achieving the dual goals of environmental protection and wastes re-utilization.
