3155.----- [RUHRCHEMIE, A. G.] [Production of Oxygenated Derivatives of Aliphatic Hydrocarbons.] French Patent 869,163, Jan. 26, 1942: appl. filed Jan. 10, 1941. Chem. Zentralb., 1942, I, p. 3039.

Fatty acids and alcohols are formed by the catalytic reaction CO and H₂ on olefins, which have first been fractionated. Example: A mixture of olefins b. 150°-350° is broken down into 4 fractions. (1) 165°-220°=olefins C₁₀-C₁₂; (2) 220°-255°=olefins C₁₃-C₁₄; (3) 255°-295°=olefins C15-C16; (4) 295°-330°=olefins C₁₇-C₁₉. The aldehydes ad alcohols thus obtained are easily oxidized to fatty acids. The products possess a high degree of purity.
