  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.

  本发明涉及一种精制烯烃的方法，该方法包括使用含有铜（I）卤化物的吡咯烷鎓基或哌啶鎓基离子液体混合物去除烯烃中含有的少量炔烃。根据本发明的方法，铜（I）卤化物通过吡咯烷鎓基或哌啶鎓基离子液体得到稳定，从而抑制Cu(I)氧化成Cu(II)，使得去除炔烃的能力可以长时间维持，并且显著提高烯烃中炔烃的选择性去除率。另外，由于本发明方法中使用的含有铜（I）卤化物的离子液体混合物既适用于吸收过程也适用于提取过程，因此与现有的吸附和膜分离过程相比，可以以更简单和经济的方式有效地从烯烃中去除炔烃。
