ABSTRACT:
An alcohol is produced from a compound having an alkenyl group by a hydroformylation of said compound having an alkenyl group in a substantially water immiscible solvent in the presence of a hydroformylation catalyst which is soluble in said solvent and a hydrogenation of the reaction mixture in the presence of a hydrogenation catalyst.
Water is added at a ratio of 0.5 to 30 times by weight base on an aldehyde produced by said hydroformylation before said hydrogenation, and an organic phase containing the hydroformylation catalyst component is separated from a water phase containing the alcohol produced by said hydrogenation and said organic phase is recycled into said hydroformylation.
The compound having an alkenyl group is an aliphatic olefin, a hydroxyolefin, and olefin ether or an olefin ester and the corresponding saturated alcohol having one more carbon atom is produced.
