      1476.  ------.  [I. G. FARBENINDUSTRIE, A. G.]  [Producing Oxygenated Organic Compounds.]  German Patent Appl. I 74,240. OZ 13,972. filed Feb. 2, 1943 (Cl. IV d-12 o).  TOM Reel 36, bag. 3,454. item 21. 7 pp.: Meyer Transl. PC-S-V. Oxo. vol. 2, chap. 33, 1949. p. 7.

            In producing oxygenated compounds by adding CO and H₂ to hydrocarbons with at least 4 C-atoms in a straight chain and with olefinic double bonds, the raw material before contact with CO and H₂, is exposed to Co carbonyl or to Co or other Co compounds and CO under pressure and at slightly raised temperature, preferably >100º.  Example: 100 parts of a dodecylene with terminal double bonds is treated with 4 parts of a catalyst (30 Co: 2 ThO₂: 2 MgO: 66% kieselguhr, in a pressure vessel for 15 min. and with CO at 160º and 100 atm.  After cooling and expanding, CO and H₂ are added at 135º.  The alcohol mixture obtained by subsequent hydrogenation at 190º with H₂ at 200 atm. is a highly branched alcohol mixture.
