Abstract
A process of removing unsaturated hydrocarbons containing at least one non-aromatic unsaturation from feedstreams which comprises contacting the feedstream with at least one of Cu.sub.2 O or Ag.sub.2 O and a fluorinated acetylacetonate of the formula ##STR1## where R.sup.1 is C.sub.1 -C.sub.6 fluoroalkyl, C.sub.1 -C.sub.8 alkyl, C.sub.4 -C.sub.6 heterocycle containing O, S or N or C.sub.6 -C.sub.10 aryl, R.sup.2 is H or C.sub.1 -C.sub.6 alkyl with the proviso that R.sup.1 and R.sup.2 together with the carbons to which they are attached may be joined together to form a C.sub.6 ring and n is from 1 to 8, in an inert organic solvent.
