氨基酸离子液体是一类新型的功能化离子液体,除了具有常规离子液体的低蒸汽压、低熔点、宽液程、溶解性好和稳定性高等性质外,还具有很强的氢键网络结构、稳定的手性中心、双配位基团、生物兼容性和可生物降解等许多独特的性质。本文综述了近年来氨基酸离子液体在溶解生物质、气体吸收、手性分离、催化等方面的应用研究进展。 Amino acid ionic liquids are a new class of functionalized ionic liquids. In addition to the low vapor pressure, low melting point, wide liquid phase, good solubility and high stability of the conventional ionic liquids, the amino acid ionic liquids also have strong hydrogen bonding network structures, Stable chiral centers, bidentate groups, biocompatibility and many other unique properties such as biodegradability. This review summarizes the application of amino acid ionic liquids in dissolved biomass, gas absorption, chiral separation and catalysis in recent years.
