2563. ------. [OWEN, J. J.] (Standard Oil Development Co.). [Synthesis of Aldehydes and Secondary Alcohols.] French Patent 962,947, June 23, 1950; appl. filed Mar. 8, 1948, in United States May 9, 1947. Chem. Zentralb., 1950, II, p. 2369.

Olefins are reacted with CO and H₂ in the presence of a catalyst consisting of Fe on an inert support. Aldehydes are formed in the 1^st stage of the process and then these are catalytically hydrogenated to the corresponding secondary alcohols. The synthesis catalyst consists of 20-40% Fe, 0.3-3.0% Cu, 50-75% kieselguhr and 0.05-1.0% K₂CO₃. Diisobutylene is converted at 135° and at 210 atm. pressure with CO and H₂. The product has the following constants: Carbonyl number 257, hydroxyl number 41, saponification number 13, and acid number 0.7. It is hydrogenated with Ni on a support at 177° and 189 atm. pressure. The same constants for the hydrogenation products are 186, 1, 32, and 0.2, respectively.
