    摘要: There are provided an ionic liquid having ether group(s) in which a copper(I) compound is included, a method for preparing the same, and a method for removing traces amounts of acetylene-based hydrocarbon compounds included in olefin by absorption or extraction using the same. When the disclosed solution is used, oxidation of Cu(I) to Cu(II) is prevented since CuX is stabilized by the ionic liquid. Thus, selective removal efficiency of acetylenic compounds is improved greatly while the removal performance is retained for a long period of time. Further, since the solution according to the present disclosure is applicable as an extractant as well as an absorbent, the associated operation is simple and apparatus cost can be decreased.

    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.

    摘要: The present invention relates to a process for removing acetylenes from olefins by using an ionic liquid-based solution, and particularly to a process for removing a small amount of acetylenes contained in olefins by using an ionic liquid-based solution where copper halide (CuX, X=halogen atom) is dissolved. In an ionic liquid-based solution used in the present invention, copper halide (CuX) is stabilized by ionic liquid, thus preventing monovalent copper ion (Cu+) from being oxidized into divalent copper ion (Cu2+), maintaining the superior activity of monovalent copper ion (Cu+) in removing acetylene for a long period of time, and remarkably increasing the selective removal of acetylene-based compounds. Moreover, an ionic liquid-based solution used in the present invention may serve as an extracting solution as well as an absorbent, thereby facilitating the operation and reducing equipment cost in comparison to the conventional extracting agent used in a slurry phase.
