ABSTRACT:
An olefin of a heavier molecular weight than the feed olefin in a hydroformylation reaction process is used as an absorbent for recovering hydro cobalt carbonyl stripped from an oxonation reactor product. The cobalt in the stripping gas is completely absorbed but light hydrocarbons, e.g., hydrocarbons having a carbon number of C.sub.7 or less, are only partially absorbed, thus permitting hydro cobalt carbonyl to be recycled to the oxonation reactor without a continuing concentration build up of light hydrocarbons, e.g., paraffins.
