The invention is directed to an ionic liquid comprising (i) a cationic portion containing a complex of a silver (I) ion and one or more neutral ligands selected from organoamides, organoamines, olefins, and organonitriles, and (ii) an anionic portion having the chemical formula
wherein m and n are independently 0 or an integer of 1 or above, and p is 0 or 1, provided that when p is 0, the group —N—SO

subtended by p is replaced with an oxide atom connected to the shown sulfur atom. The invention is also directed to a method for separating an olefin from an olefin-paraffin mixture by passing the mixture through a layer of the ionic liquid described above.
该发明涉及一种离子液体,包括(i)含有银(I)离子的阳离子部分,该离子与来自有机酰胺、有机胺、烯烃和有机腈中选择的一个或多个中性配体形成的络合物,以及(ii)具有化学式的阴离子部分,其中m和n独立地为0或大于1的整数,p为0或1,但当p为0时,由p支撑的基团—N—SO2—(CF2)nCF3将被连接到所示硫原子的氧原子替代。该发明还涉及一种从烯烃烷烃混合物中分离烯烃的方法,通过将混合物经过上述离子液体的一层来实现。
