Disclosed is the use of a Raney cobalt catalyst in the hydrogenation process for the production of n-butanol. A process for the production of purified n-butanol comprising contacting in a hydrogenation zone n-butyraldehyde and hydrogen with an active porous cobalt catalyst under hydrogenation conditions of temperature and pressure for the production of alcohols from aldehydes, either in the substantial absence of water, or in the presence of water in an amount up to about 6 wt % based on the weight of the liquid hydrogenation reaction product to produce said reaction product comprising n-butanol, and purifying said reaction product by fractional distillation in the presence of about 0.01 to about 6 wt % of water, based on the total weight of feed to the fractionating column.

Process for the production of n-butanol

A process for the production of purified n-propanol comprising contacting in a hydrogenation zone propionaldehyde and hydrogen with an active porous cobalt catalyst under hydrogenation conditions of temperature and pressure for the production of alcohols from aldehydes, either in the substantial absence of water, or in the presence of water in an amount up to about 3 wt % based on the weight of the liquid hydrogenation reaction product, to produce said reaction product comprising n-propanol, and purifying said reaction product by fractional distillation in the substantial absence of water, or in the presence of water in an amount up to about 3 wt % based on the total weight of feed to the fractionating column.
