2200. ------. [MCGRATH, H. G., PASSINO, H. J., AND RUBIN, L. C.] (M. W. Kellogg Co.). Separation of Organic Compounds. United States Patent 2,571,151, Oct. 16, 1951; appl. filed Nov. 14, 1946, Serial No. 709,872; 18 claims (Cl. 260-450). Chem. Abs., vol. 46, 1952, p. 711.

Organic acids and alcohols contained in an oil product liquid phase obtained from the condensation of the reaction product produced in the catalytic hydrogenation of CO are recovered by fractionating the oil product into a fraction b. < 200° F., 1> 430° F., and an intermediate one comprising hydrocarbons, organic acids, and alcohols. This last-named fraction is extracted with a solvent comprising a light alcohol, such as MeOH, EtOH, PrOH, or ethylene glycol, to produce an extract phase comprising organic acids and alcohols and a raffinate phase comprising hydrocarbons and then separating the 2 phases thus produced. Descriptive flowsheets included.
