3288. ----- [SCHMIDT, O, AND UFER, H.].  (I. G. Farbenindustrie A. G.).  [Methyl Alcohol.] German Patent 600,677, July 28, 1934 (Cl. 12 o-5.01). Chem. Abs., vol. 28, 1934, p. 7267.

In preparing MeOH by the catalytic reduction of CO by H₂  under high temperature and pressure, the mixture of CO and H₂ in suitable proportions is passed over the catalyst at 200°-250°.  The catalyst contains 1 or more catalytic elements, together with V or Mn or both. Cr or neighboring elements of the 6^th group are not used with Mn.  Thus, the catalyst may be prepared by dissolving CdCO₃ in HNO₃, adding Zn(NO₃)₂ and Mn(NO₃)₃ and precipitating by adding K₂CO₃.  The precipitate is washed and mixed with a carrier, such as pumice, and dried to form the catalyst. The reaction temperature is 250°-300° for this catalyst.
