1857.  KING, C. C., AND DICKINSON, N. L. (M. W. Kellogg Co.). Separation of Organic Compounds. Unites States Patent 2,552,564, May 15, 1951; appl. filed Feb. 27, 1947, Serial No. 731,268; 14 claims (Cl. 260-450). Chem. Abs., vol. 45, 1951, p. 9555.

MeOH and H₂O in approximate proportions of 90% MeOH and 10% H₂O is found to be a very satisfactory selective extraction agent when used for the separation of H₂O-insoluble oxygenated compounds obtained from the condensation of reactor gases in the catalytic hydrogenation of C oxides. After the alcoholic solvent treatment, a relatively low-boiling hydrocarbon is introduced into the extraction zone as a wash oil, which causes the formation of a raffinate phase comprising hydrocarbons and an aqueous extract phase comprising oxygenated compounds. The phases are withdrawn and separated. The raffinate phase is further distilled to produce a high- and low-boiling fraction, the latter being utilizable as a wash oil. 8 United States patents cited.
