British Patent 337,014, July 24, 1929. Chem. Abs., vol, 25, 1931, p. 1839. Compounds such as EtOH, HOAc, acetaldehyde, MeOAc, and higher homologs are made using catalysts comprising ferrites, ferrates, cobaltites, or cobaltates, such as those of alkali or alkaline earth metals or of Al, preferably at 200º-600º (suitably 250º-350º) under 50-500 atm. or higher pressure. Coke-oven gases may be used, producer or water gas, which may be preliminarily treated if desired to form synthetic products such as MeOH or EtOH in the presence of a catalyst such as ZnO or a basic chromate. The catalysts may be used in connection with Zn, Mg, Ca, Al, Cr, Mo, V, W, or U or their oxides or other compounds. Cu may be present and the apparatus may be of Cu or steel lined with Cu or of steel containing Mo, W, Co, or Ni. See also United States Patent 1,996,101 (abs. 555). |
