2586. ------. [PARKER, P. T., AND HILLARD, G. O.] (Standard Oil Development Co.). [Oxygenated Compounds From Synthesis Gas and Olefins.] French Patent 954,563, Dec. 28, 1949; appl. filed Oct. 22, 1947, in United States Oct. 25, 1946. Chem. Zentralb., 1950, II, p. 340.

Oxygenated compounds, particularly alcohols, with 2-18 C atoms are produced from CO+H₂ and olefins in presence of a Fe, Co, or Ni catalyst. The operation is performed in 2 reaction zones whereby the reaction product from the 1^st zone, which contains the metal catalysts in the form of carbonyl compounds, is carried over into the 2d zone, where it is treated with H₂, thus regenerating the metal catalyst. The olefin mixture is heated with a synthesis gas, which contains about 44% CO and 55% H₂, in the 1^st reaction zone in the presence of a Co catalyst to 121°-204° at a pressure of 100-300 atm. The conversion mixture is separated into a gaseous and a liquid product by cooling, the liquid product being passed into the 2d reaction zone where it meets a stream of H₂. Both components, the liquid mixture and the H₂, are passed from bottom to top of the Co catalyst located herein. The temperature here is 121°-204°, the pressure 100-200 atm., and the time of contact 15-60 min. or more. In the 2d chamber, the aldehydes, produced in the 1^st chamber as an intermediate product, are converted into alcohols by contact with the H₂.
