ABSTRACT:
This invention relates to a hydroformylation process for producing a 1,6-hexanedial which comprises reacting a butadiene with hydrogen and carbon monoxide in the presence of a catalytic amount of rhodium complexed with certain poly-phosphite ligands to achieve high conversions of the butadiene to the 1,6-hexanedial.
