2027. ------. [LAZIER, W. A.] Catalysts for Methanol Synthesis. British Patent 272,555, June 12, 1926. Chem. Abs., vol. 22, 1928, p. 1782.

Catalysts are prepared by (a) igniting a metallic chromate or dichromate at 600°-1,000°; or (b) prolonged heating to redness of mixtures of metallic oxides or salts such as chlorides with alkali chromates or dichromates; or, (c) igniting at redness a double chromate or dichromate of a metal with NH₃ or an organic base, such as aniline and pyridine. The product is preferably washed with a weak acid, such as diluted HOAc, to remove compounds other than chromites, and the porous material is then dried. It may be used in MeOH synthesis or for producing other oxygenated organic compounds for producing H₂ from CO and steam or for dehydrogenation processes, such as production of aldehyde from alcohol. For producing MeOH, the chromites of Zn, Cu, Cd, Mg, Mn, Ag, and Fe or their mixtures are suitable. Several examples given.
