离子液体的非常规制备技术研究进展

摘要

离子液体的大规模应用有赖于其制备技术的不断进步。然而,常规制备方法反应时间长、产品纯化繁琐、不宜规模化等问题,制约着离子液体的工业化应用进程。针对离子液体制备过程的关键环节,综述了目前离子液体非常规制备技术的研究进展,重点介绍了微波、超声波、微波-超声、微反应和STT过程强化制备离子液体的技术研究现状,指出现阶段虽然非常规制备技术取得了重要进展,但是仍然需要通过深入细致的研究,建立完善的理论指导体系,同时还要加快功能化离子液体和绿色化制备技术开发。%Large-scale application of ionic liquids depends on the continuous advancement of preparation technology.However,the classic procedure for ionic liquids synthesis is excessively time-consuming and unsuitable for mass production,which restricts industrial application of ionic liquids.Aiming at the key process in ionic liquids preparation,the research progress of the non-conventional techniques for preparation of ionic liquids is summarized.The current ionic liquids preparation technologies,such as microwave,ultrasound,microwave-ultrasound,microreactor and Spinning Tube-in-Tube（STT） process intensification are reviewed.Although important progress has been made in non-conventional preparation technique at this stage,intensive research work is still required in order to establish theoretical guidance,and the development of task-functionalized ionic liquids and green preparation technique should be accelerated.
