Abstract: 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.
