ABSTRACT:
A catalyst of the general structure ##STR1## is an effective hydroformylation catalyst at temperatures of from about 60.degree. to about 150.degree. C. and hydrogen carbon monoxide gas pressures of from about 300 to about 3500 psig for both primary and internal olefins producing an increased amount of linear normal aldehydes through olefin isomerization. When the reactor gas is altered to essentially pure hydrogen, the catalyst further converts aldehydes formed by hydroformylation to alcohols under the same reaction conditions. The catalyst is air insensitive, stable, and highly recoverable by simple means. P is a heterocyclic nitrogen-containing polymer with available pyridine linkages and n is 1 or 2.
