Title: Improvements in or relating to methyl ether
IPC: C07C41/34
Filed: 1927-09-23
Abstract: 278,353. Delco-Light Co., (Assignees of Bichowsky, F. R.). Sept. 28, 1926, [Convention date]. Methyl ether is prepared by passing a mixture of carbon monoxide and hydrogen at elevated temperature and pressure first over an hydrogenation catalyst and then over a dehydration catalyst or over a mixture of both catalysts, or by passing methyl alcohol under the same temperature and pressure conditions over a dehydration catalyst. Inert gases such as carbon dioxide may be present and the process may be operated in a circular system. The hydrogenation catalyst should be one which does not favour the production of methane, e.g. zinc oxide and reduced copper or chromium salts, but excluding iron; alumina prepared by partially dehydrating aluminium hydroxide at 300‹ C., as also partially dehydrated titanium hydroxide, thorium hydroxide or silica gel, are mentioned as dehydration catalysts. Preferably a temperature of 500‹ C. and pressures of more than 125 atmospheres are employed for the hydrogenation step, and a temperature of 300‹ C. with a pressure of 25 atmospheres or more for the dehydration stage. In the process described with reference to the Figure, a mixture of two or more parts of carbon monoxide with one part of hydrogen is passed at 150 atmospheres pressure through a steel reaction chamber 10, internally lined with inert material. The front part 11 may contain the hyrogenation catalyst and the rear part 12 the dehydration catalyst, or the whole chamber may be filled with a mixture of the catalysts, but in either case it is preferred to heat the front part to a higher temperature than the rear part. By a suitable construction of the chamber, the pressure may be made to drop to 25 atmospheres at the outlet. The reaction products are cooled in a condenser 17 to a solution of methyl ether in water, which collects in a high-pressure tank 21 and then passes to a further tank 19 'where the ether is separated by releasing the pressure. Uncombined gases, and any inert gas when such is employed, are drawn, off from the high-pressure tank 21 and returned by the pump 24 to the reaction chamber. Additional water for making the solution may be introduced at 18. The tank 21 may be dispensed with.
