ABSTRACT:
A process for absorbing olefinically-unsaturated hydrocarbon compounds from feedstreams containing such compounds by contacting said feed streams with metal-diketone absorbents of the formula: ##STR1## wherein R.sub.1 is trichloroemthyl or R.sub.F ; R.sub.F is C.sub.n F.sub.2n+1 and n is 1-8; R.sub.2 is H or hydrocarbyl of 2-20 carbon atoms having at least one olefinic unsaturated bond; M.sup.I is Cu.sup.I or Ag.sup.I and R.sub.3 is hydrocarbyl of 2-20 carbon atoms having at least one olefinic unsaturated bond.
