ABSTRACT:
Catalysts which comprise metal carbonyls or organometallic complexes in which the metal portion of the complex is selected from a Group VIII metal are useful in hydroformylation reactions. The catalysts which are homogeneous in nature may be recovered from the hydroformylation products by treating the catalyst complex with a nitrogen-containing compound in an aqueous phase whereby said catalyst may be easily separated from the hydroformylation products and recovered.
