GAS PHASE HYDROFORMYLATION PROCESS

GAS PHASE HYDROFORMYLATION PROCESS

A gas phase catalytic hydroformylation process for producing at least one aldehyde product in the presence of a transition metal-ligand complex hydroformylation catalyst and water vapor. Surprisingly, catalyst activity can be sustained by having traces of water vapor in the feed stream. Additionally...

Zusammenfassung:A gas phase catalytic hydroformylation process for producing at least one aldehyde product in the presence of a transition metal-ligand complex hydroformylation catalyst and water vapor. Surprisingly, catalyst activity can be sustained by having traces of water vapor in the feed stream. Additionally, additional ligand can be added to replace lost ligand to maintain activity. In addition, it has been found that treatment of the catalyst with a buffer can rejuvenate catalyst activity.
