Abstract
A process for separating a gaseous alkene mixture into components thereof which comprises contacting the gaseous alkene mixture with a cuprous complex of the formula [Cu(facac)].sub.x L.sub.y where facac is a fluorinated acetylacetonate and L is a stabilizing agent in an organic solvent wherein L is displaced by alkene. Cuprous complexes containing alkene can then be separated provided that the separation factor between alkene complex to be separated and other alkene complexes is at least about 1.05.
