Abstract
Carbon monoxide is selectively removed from a gas stream by a process which comprises contacting the gas stream with an absorbent solution containing the reaction product of a Cu(I) compound and a halogenated acetylacetone of the formula: ##STR1## where X is a halogen, R.sub.1 is CX.sub.3, linear or branched C.sub.1 to C.sub.8 alkyl, C.sub.4 to C.sub.6 heterocycle containing O, S or N or C.sub.6 to C.sub.10 aryl, R.sub.2 is hydrogen or C.sub.1 to C.sub.6 alkyl, or R.sub.1 and R.sub.2 are joined together to form a C.sub.6 ring.
