ABSTRACT:
A hydroformylation process for increasing the yield of straight chain unsubstituted primary alcohols from predominantly terminal olefins by contacting the olefins with carbon monoxide and hydrogen in the presence of a cobalt catalyst is characterized by the incorporation of aqueous base in a base to cobalt molar ratio of about 10:1 to 20:1 in the reaction mixture before or after heating the same to reaction temperature. The base introduced in the oxo reactor while hydroformylation is occurring continuously converts by-products acetals and esters to the corresponding primary alcohols, thereby considerably increasing the yield thereof.
