Aldehydes and ketones can be reduced to alcohols by H2 and CO in the presence of a Co catalyst, and the reaction can be applied to the reduction of compounds containing S. A free radical mechanism is proposed for the hydrogenation. When olefins are treated with 150-300 atm. of synthesis gas and a Co catalyst at 180°-185°, alcohols containing 1 C atom more than the olefin are the principal products. Double bonds in some compounds, when treated under these conditions, are hydrogenated rather than hydroformylated. (See abs. 3652.)
