Novel metal-diketone absorbents for carbon monoxide

摘要

A process for absorbing carbon monoxide and/or olefinically-unsaturated compounds from feedstreams containing such compounds by contacting the feed streams with metal-diketone absorbents of the formula: <IMAGE> wherein R1 is trichloromethyl or RF; RF is CnF2n+1 and n is 1-8; R2 is H or hydrocarbyl of 2-20 carbon atoms having at least one olefinic unsaturated bond; MI is CuI or AgI and R3 is hydrocarbyl of 2-20 carbon atoms having at least one olefinic unsaturated bond.
