2194. MCGRATH, H. G., AND BURTON, W. P. (M. W. Kellogg Co.). [Processing the Reaction Products of Carbon Monoxide Hydrogenation for the Separation of Oxygenated Compounds.] French Patent 978,270, Apr. 11, 1951; appl. filed Dec. 28, 1948. Chem. Zentralb., 1952, I, p. 3733.

The cooled mixture is separated into a gaseous, non-condensed product, an oily, and an aqueous condensate. The oily condensate is washed with H₂O, a part of the oxygenated compounds being absorbed. The aqueous and the oily condensates are distilled with the separation of a proportional high-boiling fraction. This fraction is utilized for washing the noncondensed gaseous product, thereby obtaining an aqueous solution of oxygenated products, which is worked up. The oily condensate after being washed with H₂O is extracted with aqueous alcohol, whereby the greater part of the oxygenated organic compounds is adsorbed. These extracted oxygenated compounds, which contain aldehydes and ketones, are hydrogenated thereby being partly converted into the corresponding alcohols.
