    摘要: An improved method for the manufacture of MIBK and DIBK from DMK and/or IPA, by reacting, in the presence of an aldol condensation catalyst, a gaseous mixture comprising hydrogen and DMK and/or IPA. The improvement is the use of a reaction pressure greater than 207 kPa (30 psig) to increase the ratio of MIBK to DIBK. In addition a method for the manufacture of MIBK and DIBK by reacting, in the presence of an aldol condensation catalyst, a gaseous mixture consisting essentially of DMK and/or IPA and optionally water.

    摘要: 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.
