ABSTRACT:
Catalysts of the general structure ##STR1## have been found to be effective heterogeneous hydroformylation catalysts at temperature of from about 60.degree. C. to about 150.degree. C. and hydrogen to carbon monoxide (H.sub.2 /CO) gas pressures of from about 100 to about 3500 psig for both primary and internal olefins. The process produces an increased amount of linear normal aldehydes. At the completion of the hydroformylation reaction, the reactor gas can be altered to essentially pure hydrogen and the catalyst then further converts aldehyde formed by the hydroformylation reaction to alcohols under the same reaction conditions. The copolymer support acts as a ligand and allows the catalyst to be easily recovered.
