低共熔溶剂的分子结构及物性估算的研究进展

Molecular Structure and Physical Property Estimation of Deep Eutectic Solvents(DESs)

低共熔溶剂具有熔点低、不挥发、不易燃、溶解性良好、易合成、廉价、低毒、腐蚀性低、生物降解性好等特点,常被作为"绿色"溶剂应用于金属加工和合成反应中。然而,目前对低共熔溶剂的结构和性质的研究只限于少部分具体的低共熔溶剂,没有形成系统全面的理论体系。简述了低共熔溶剂的合成与分类、分子结构和形成机理的研究进展,归纳了低共熔溶剂的物性估算方法,并指出了一些关于低共熔溶剂研究中存在的问题,提出了可能的解决方案。

The physical properties of deep eutectic solvents（ DESs） have low melting point,nonvolatile,nonflammability,good solubility.And DESs are cheaper,easier to synthesize and possess lower eco-toxicity,lower corrosivity as well as favorable biodegradability,thus they have quite good potential for application in metal processing and synthesis reactions. However,the structure and properties research of DESs limited to some specific DESs,there is no a comprehensive theoretical system.In this work,the synthesis methods,classification,molecular structure,formation mechanism,and other properties of DESs were reviewed,and the estimation of physical properties were concluded.Moreover,the latent problems and probable solution about the research of DESs are discussed.
