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.
提供了一种含有醚基的离子液体,其中包括铜(I)化合物,以及制备该离子液体的方法和使用该离子液体通过吸收或萃取去除烯烃中包含的微量乙炔基碳氢化合物的方法。当使用所披露的溶液时,由于离子液体稳定了CuX,防止了Cu(I)氧化为Cu(II)。因此,乙炔化合物的选择性去除效率大大提高,同时保持了长时间的去除性能。此外,由于根据本公开的溶液可用作萃取剂和吸收剂,相关操作简单,设备成本可以降低。
