2679. PIER, M., RUMPF, W., AND STEIN, G. (I. G. Farbenindustrie A. G.) [Oxygenated Organic Compounds.] German Patent 490,248, Feb. 25, 1923. Chem. Zentralb., 1930, I, p. 3133; Chem. Abs., vol. 24, 1930, p. 2137.

In the manufacture of oxygenated organic compounds by the catalytic interaction of CO and H₂ at a raised temperature and under high pressure, the reaction vessel is made of, or lined with, Cu or Ag or their alloys, and the other parts of the apparatus coming in contact with CO are constructed similarly or made of, or lined with, more fusible metals, for example, Al, Sn, Zn, or Pb or their alloys. Contamination of the contact mass with Fe is so avoided.
