1379. ------. [I. G. FARBENINDUSTRIE, A. G.] [Oxygenated Organic Compounds From Carbon Monoxide and Hydrogen.] German Patent 612,229. Apr. 16, 1935 (Cl. 12 6-5.01). Chem. Abs., vol. 29, 1935, p. 4771.

Parts of the apparatus having a temperature of 180º-200º, and preferably also the parts having a temperature of 150º-180º or 200º-250º, are made of or lined with material with which CO does not react to yield Fe(CO)₄. The parts at temperatures >or< the limits specified may be made of Fe, since Fe(CO)₄ is not produced at temperatures beyond those limits. The preliminary heating and aftercooling of the apparatus are preferably effected in the absence of CO.

Addition to abs. 1377, 1378, 1996, 2664, 2672, 2679.
