Abstract

The effects of the ligand to metal ratio, temperature, syngas pressure, partial pressures of H2 and CO, and new ligand structures have been examined on 12 of the most reasonable products resulting from the rhodium-catalyzed low-pressure hydroformylation of 1, 3- butadiene. The selectivity for the desired linear dihydroformylation product, 1, 6-hexanedial (adipic aldehyde), is essentially independent of all of these reaction parameters, except ...
