ABSTRACT:
A catalyst of the general structure P --M Cl.sub.3 wherein M is rhodium or iridium and P is a heterocyclic nitrogen-containing polymer has been found to be an effective heterogeneous hydroformylation catalyst at temperatures of from about 60.degree. to about 150.degree. C. and H.sub.2 /CO gas pressures of from about 300 to about 3500 psig for most primary and internal olefins, producing an increased amount of linear normal aldehydes. When the reactor gas is altered to hydrogen, the catalyst further converts aldehydes formed by hydroformylation to alcohols under the same reaction conditions. The catalyst is oxygen stable, heterogeneous, and easily recovered.
