摘要
基于全氟有机超酸的离子液体作为含氟材料表现出独特的性质和优异的性能,介绍了基于全氟有机超酸,如全氟烷基磺酸和双(全氟烷基磺酰)亚胺等离子液体及其性质,总结了此类离子液体在作为绿色溶剂、分离介质、催化剂和改性材料等方面的研究与应用情况。认为今后研究需提高离子液体纯度、稳定性并降低粘度,进一步降低成本、深度开发适合大规模工业应用的工艺,提供离子液体的毒性、生物降解性及对环境的影响数据。
As fluorine-containing materials,ionic liquids based on perfluorinated organic super acid showed unique properties and excellent performances.The properties of ionic liquids based on perfluorinated organic super acid such as perfluoroalkyl sulfonic and bis(perfluoroalkyl sulfonyl)imide were briefly summarized.The emphasis was focused on research and applications of ionic liquids in the fields of green solvents,separation media,catalysts and modification materials.That future research needs to improve the purity and stability of ionic liquids and reduce the viscosity,further reduce the cost,deeply develop process suitable for large-scale industrial application,provide toxicity,biodegradability and the environmental impact data of ionic liquid.
