ABSTRACT:
An improved process for producing alcohols which comprises passing a demetalled hydroformylation liquid effluent comprising aldehyde and alcohol and containing acetal impurities to a thermal treatment zone; subjecting the demetalled hydroformylation effluent in the thermal treatment zone in the absence of added acidic compounds and in the presence of water to a temperature of from about 350.degree. to 500.degree. F. for a time sufficient to convert at least a major portion of the acetal impurities to the corresponding aldehydes and alcohols and to form an aldehyde-containing liquid containing substantially reduced levels of the acetal impurities; withdrawing the aldehyde-containing liquid from the thermal treatment zone and rapidly cooling the liquid to a temperature of about 300.degree. F. or below; and passing the cooled liquid to a hydrogenation zone for hydrogenation in the presence of a hydrogenation catalyst and gaseous hydrogen of at least a portion of the aldehydes to the corresponding alcohols at a temperature of from about 150.degree. to 350.degree. F.
