3437. ----- [SOENKSEN, H., AND GRASSHOF, H] (W. E. Currie). Recovery of Higher Oxygen Containing Organic Compounds From Crude Oils Produced by the Catalytic Hydrogenation of Carbon Oxides. United States Patent 2,274,750, Mar. 3, 1942; appl. filed Aug. 16, 1939; 7 claims (Cl 260-450). Chem. Abs., vol. 36, 1942, p. 4320.

Process is employed for treating a crude oil such as that produced by the catalytic hydrogenation of CO, which involves subjecting such crude oil to an intense extraction with an organic solvent, such as isopentane, having a preferential solvent action on the higher boiling O-containing substances, while adding a highly soluble alkali metal compound such as K₂CO₃ which reduces the solubility of such higher boiling products in the portion miscible with H₂O in such a quantity that the resulting mixture contains a concentrated solution thereof, and separating the higher boiling products with the solvent in which they have dissolved.
