摘要： The present invention relates to a method of purifying olefin, the method comprising removing a small amount of acetylenic compounds contained in olefin by using pyrrolidinium-based or piperidinium-based ionic liquid mixtures comprising copper (I) halide. According to the method of the present invention, copper (I) halide is stabilized by pyrrolidinium-based or piperidinium-based ionic liquids, suppressing the oxidation of Cu(I) into Cu(II), whereby the capacity of removing acetylenic compounds can be maintained for a long time and the selective removal rate of acetylenic compounds to olefin can be significantly improved. In addition, since the ionic liquid mixtures comprising copper (I) halide used in the method of the present invention can be applied to both absorption and extraction processes, it can effectively remove acetylenic compounds from olefin in a more simple and economical way compared to the existing adsorption and membrane separation processes.
