2584. -----. [PARKER, P. T.] (Standard Oil Development Co.). Synthesis of Oxygenated Organic Compounds. United States Patent 2,530,989, Nov. 21, 1950; appl. filed June 5, 1947, Serial No. 752,800; 9 claims (Cl. 260-632). Chem. Abs., vol. 45, 1951, p. 1752.

In producing oxygenated organic compounds from olefins, CO, and H₂, the total product from the oxygenation stage of a 2-stage process is distilled to separate unreacted olefins from oxygenated products. The olefins are recycled to the oxygenation stage. Aldehyde condensation is suppressed by carrying out the distillation at reduced pressure 5-500 mm. Hg, depending on the boiling range of the olefins originally charged.
