Abstract:
The invention relates to (1) the preparation of a catalyst comprising cobalt carbonyl in admixture with a metal substance selected from the group consisting of a metal of Groups I or II of the Periodic Table, useful as an oxo reaction catalyst by reacting the corresponding free metals or a compound thereof in a liquid medium with carbon monoxide and hydrogen in the presence of palladium, platinum or gold; (2) regenerating spent cobalt catalysts of the foregoing type by applying the same reagents and conditions to the spent catalyst.
