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.
