1739. KEULEMANS, A. I. M., KWANTES, A., AND VAN BAVEL, T. [Structure of Formylation (Oxo) Products Obtained From Olefins and Water Gas.] Rec. Trav. Chim., vol. 67, 1948, pp. 298-308; British Abs., 1949, A. II, p. 2; Chem. Abs., vol. 42, 1948, p. 8152.

Formylation of olefins by means of CO and H₂ at 120°-160° and 100-200 atm. in presence of the Fischer-Tropsch Co catalyst is studied with 16 alkenes containing 3-8 C, cyclopentene, and cyclohexene. The aldehydes formed are immediately hydrogenated in the same autoclave with pure H₂ to alcohols. Analysis of the products of reaction is simplified if the alcohols are dehydrated by pyrolysis of their stearates, and the olefins obtained are hydrogenated to alkanes.
