Abstract
Abstract This specification discloses a process for the production of an alcohol by reacting an aldehyde or an acetal with hydrogen in the presence of carbon monoxide, and as a catalyst, an insoluble polymer containing a functional group, which may be an amine, thiol, phosphine, or arsine group, having chemically bonded thereto a metal of Group VIII of the Periodic Table.

Claim 1
Independent Claim
151 words
A process for producing alcohols comprising reacting a reducible aldehyde or an acetal thereof, said aldehyde having about 3 to 13 carbon atoms, corresponding to said alcohol with about 1 to 20 moles of hydrogen per mole of aldehyde or acetal, in the presence of about 0.1 to 20 moles of carbon monoxide per mole of hydrogen at about 50° to 250° C in contact with an intrinsically porous catalyst which is essentially insoluble in the reaction mixture comprising said aldehyde or acetal and the reaction products thereof with hydrogen, which catalyst comprises an organic polymer selected from the group consisting of cellulose, poly(styrene-divinyl benzene), poly(phenol-formaldehyde), poly(melamine-formaldehyde), poly(ureaformaldehyde), poly(alkylene-formaldehyde) and polystyrene having a tertiary amine having a pK b of 3 to 7 and containing at least one alkyl substituent bonded thereto; and having a metal moiety selected from the group consisting of cobalt, rhodium and ruthenium bonded to said amine.
