Abstract
An aromatic solution of the compound CuAl(CN)Cl.sub.3 alone or with additional solid CuAl(CN)Cl.sub.3 is used for the separation of some unsaturated compound (olefin, acetylene or carbon monoxide) from a feedstream. The feedstream is contacted with the solvent to form a complex of the ligand (olefin, acetylene or carbon monoxide). The feedstream is then separated from the solvent. The solvent is then treated with some combination of heat and lowered pressure to separate the ligand from the solvent. The ligand poor solvent is then recycled to contact fresh feedstream.
