Abstract

Alkenes, alkynes or mixtures thereof are removed from feedstreams by a process which comprises contacting the feedstream with a solution of a cuprous fluorinated acetylacetone in an organic solvent containing stabilizing agent to remove alkene, alkyne or mixture thereof by forming a first cuprous complex, decomposing the first cuprous complex whereby stabilizing agent replaces alkene or alkyne in the first cuprous complex to form a second cuprous complex, and separating the displaced component. The formation of the second cuprous complex avoids any deposition of copper metal upon heating.
