2029. ------. [LAZIER, W. A.]. Catalytic Production of Oxygenated Carbon Compounds. British Patent 301,806, June 12, 1926. Chem. Abs., vol. 23, 1929, p. 4306.

Catalysts for use in reactions such as that of CO with H₂ or steam or in dehydrogenation of compounds such at EtOH are prepared by heating to decomposition a double chromate of a nitrogenous base such as NH₄ or pyridine and 1 of the metals Zn, Cu, Cd, Mg, Mn, Ag, and Fe. The catalysts may be rendered more active by leaching with a "weak" acid such as 5-10% HOAc. Examples are given of the production of MeOH and higher alcohols from CO and H₂. Preparation of basic ZnNH₄ chromate, MnNH₄ chromate, and Zn bichromate tetrapyridine described.
