1947. ------. [KRAUCH, C., HOCHSCHWENDER, K., AND SCHUNCK, W.] (I. G. Farbenindustrie A. G.). Oxygenated Organic Compounds From Carbon Oxides and Hydrogen. United States Patent 1,889,251, Nov. 29, 1932; appl. filed May 22, 1924, Serial No. 715,191. Chem. Abs., vol. 27, 1933, p. 1359.

Gaseous mixture such as may be formed mainly of CO and H₂ is passed, at elevated temperature and pressure, over a catalyst such as one prepared from ZnO and K₃Cr₂O₇ by reduction with H₂ capable of inducing formation of MeOH, at a velocity so much < that required for substantially pure MeOH production that substantially all the MeOH formed is converted into higher oxygenated compounds such as higher alcohols and aldehydes.
