114. -----. Synthesis of Methanol. British Patent 254,760, Feb. 2, 1925. Chem. Abs., vol. 21, 1927, p.2703.

Synthesis of MeOH and other oxygenated organic compounds is effected from oxides of C and H₂, with Fe, Ni, Co, or their oxides as catalysts, in the form of such chemical compounds, alloys, or solid solutions as are stable, contain no free Fe, Ni, or Co, and do not form such by reduction or decomposition by the hot reducing gases. Combinations of the metals with Cu or Ag or of Co with the metals specified in British Patent 220,715 (abs. 3289) are excluded. Among the catalysts that are suitable are compounds or solid solutions of the metals specified with oxides of Cr, V, W, Zr, Al, and Ti; alloys of the metals with Mn, Cr, W, Sn, or Zn, or silicides; borides; sulfides; and phosphides or arsenides of the metals; but not carbides. Alkali metal compounds may be added. Volatile compounds of Fe, Mi, or Co should be excluded from the gases, and the exposed surfaces of the apparatus should be free from such metals; it may be formed of or lined with Cu, Al, Ag, Mn, Cr, steel V2A or Fe sulfide, or ardenide.
