2135. ------. [MARSCHNER, R. F.] (Standard Oil Co. of Indiana). Recovery of Oxygenated Compounds and Hydrocarbons From Mixtures. United States Patent 2,533,675, Dec. 12, 1950; appl. filed Oct. 30, 1945, Serial No. 625,519; 4 claims (Cl. 260-450). Chem. Abs., vol. 45, 1951, p. 2182.

Gaseous product from the hydrogenation of CO is cooled, and the normally liquid hydrocarbons are removed by condensation. The mixture separates to a gas phase, a 1^st liquid hydrocarbon phase and a 1^st aqueous phase, all containing organic oxygenated compounds. The 1^st aqueous phase is fractionated. The overhead fraction consists predominantly of low-boiling organic oxygenated compounds substantially free from organic acids. The bottom aqueous fraction contains organic acids substantially free from other organic oxygenated compounds. An intermediate aqueous fraction contains hydrocarbon-soluble substances and higher boiling H₂O-soluble organic oxygenated compounds. The 1^st liquid hydrocarbon phase is contacted with this intermediate aqueous fraction and stratified. A 2d hydrocarbon phase containing a diminished proportion of organic oxygenated compounds and a 2d aqueous phase containing a diminished proportion of hydrocarbon-soluble substances are withdrawn. 6 United States patents cited.
