低共熔溶剂的性质与应用研究进展

Research progress on the properties and applications of deep eutectic solvents

随着绿色化学的兴起,绿色低污染、无污染溶剂备受关注。低共熔溶剂被认为是一种类离子液体的新型绿色溶剂,具有低饱和蒸汽压、低熔点、无毒环保、可降解及价格低等优势。综述了低共熔溶剂的组成和种类、制备方法、理化性质(如熔点、粘度、表面张力等),以及在萃取分离、生物化工、电化学等领域的应用,并总结了目前低共熔溶剂应用存在的问题,对未来研究方向进行展望。

With the rise of green chemistry,green low pollution and pollution-free solvents have attracted much attention.Deep Eutectic Solvents are considered as a new type of green solvents for ionic liquids,which have the advantages of low saturated vapor pressure,low melting point,non-toxic and environmental protection,degradability and low price,etc.The composition and types,preparation methods,physical and chemical properties(such as melting point,viscosity,surface tension,etc.)of deep eutectic solvents,as well as their applications in extraction and separation,biochemistry,electrochemistry,and other fields were reviewed.The current problems in the application of deep eutectic solvents and looks forward to future research directions were summarized.
