2201. ------. [MCGRATH, H. G., PASSINO, H. J., AND RUBIN, L. C.] (M. W. Kellogg Co.). Separation of Oxygenated Organic Compounds From the Products of the Hydrogenation of Carbon Monoxide. United States Patent 2,635,111, Apr. 14, 1953. Chem. Abs., vol. 47, 1953, p. 7762.

Reaction products of the hydrogenation of CO are condensed to yield an aqueous phase and an oil phase. The aqueous phase is distilled to yield 2 fractions, 1 rich in organic acids, the other in alcohols and aldehydes. The latter fraction is contacted with an alkali, then the salts and excess alkali are removed and the remainder of the fraction is extracted with a low-boiling hydrocarbon, for example, pentane, to remove any hydrocarbons present. The pentane is separated from the O compounds by azeotropic distillation.
