285. ------. [BURTON, W. P.] (M. W. Kellogg Co.). Separation of Organic Compounds. United States Patent 2,647,139, July 28, 1953; appl. filed Mar. 31, 1948, Serial No. 18,202; 12 claims (Cl. 260-450).

Claim 1. A process for treating the reaction product obtained in the hydrogenation of oxides of C wherein said product comprises a mixture of hydrocarbons and oxygenated organic compounds comprising alcohols, acids, aldehydes, and ketones, which comprises: Cooling said product to effect substantial condensation of normally liquid components to form an oil product liquid phase and a H₂O product liquid phase, each of said phases containing at least a portion of said oxygenated compounds; separately scrubbing said oil product liquid phase with H₂O to obtain a H₂O layer comprising H₂O-soluble oxygenated compounds and hydrocarbons; subjecting said oil layer to extraction treatment with an aqueous solution of a H₂O-soluble alcohol to obtain a raffinate containing hydrocarbons and an extract containing oil-soluble oxygenated compounds; subjecting said extract to selective hydrogenation to convert aldehydes present to their corresponding alcohols and to form a mixture comprising alcohols and ketones: separating alcohols from ketones in the mixture thus produced; combining said H₂O layer from H₂O-scrubbing of said oil product liquid phase with said H₂O product liquid phase; fractionating the combined mixture into a relatively high boiling fraction comprising organic acids and a relatively low boiling fraction comprising alcohols, aldehydes, and ketones; subjecting said relatively low boiling fraction to selective hydrogenation to convert aldehydes present to their corresponding alcohols and to form a mixture comprising alcohols and ketones: and separating alcohols from ketones in the mixture thus produced.
