Abstract

260,888. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). June 2, 1926. Methyl alcohol.-In carrying out the synthetic manufacture of methyl alcohol in apparatus made of or lined with copper or its alloys, in order to prevent the diffusion of the reacting gases through the walls of the apparatus (which diffusion is ascribed to the presence in the copper or its alloys of small quantities of the oxides of copper and of the metals alloyed therewith, and to the reduction of those oxides by the gases), the walls of the apparatus are protected from direct contact with the reacting gases by a layer of gas which is non-reducing with respect to those oxides. For example, the apparatus mav be provided with an inner wall of copper or its alloys so that a narrow space is formed between the inner and outer walls through which space the non-reducing gas. such as nitrogen or carbon dioxide, is slowly passed. Alternatively, the narrow space may be simply filled with the non- reducing gas, but in either event the gas is preferably maintained under substantially the same pressure as the reacting gases.
