2832. ----- [ROTTIG, W.] (Ruhrchemie A. G.). Iron Catalysts for the Hydrogenation of Carbon Monoxide. United States Patent 2,628,969, Feb. 17, 1953; appl. filed Sept. 30, 1949, Serial No. 118,993; 5 Claims (Cl. 260-449.6). Chem. Abs., vol. 47, 1953, p. 5099.

Catalyst produced by precipitation of an Fe salt with an alkali compound is washed only to a point where the resulting catalyst still contains alkali compounds within the limit of 3-20% (preferably 5-10%) calculated for K₂O, of the Fe present, calculated as metallic Fe. 100-200 1. of H₂O will be sufficient to wash a catalyst mass containing 8 kg. Fe. The highest yield of oxygenated compound is obtained with this catalyst when the hydrogenation of CO is carried out under pressure of 3-20 atm. Synthesis gas rich in CO is used. Beside the conventional activators the catalyst may contain elements such as V, Ce, or W flavoring formation of O-containing compounds. The entire product obtained by this process contains 30-40% O-containing compounds, mostly alcohols. 7 United States patents cited.
