3924.  WIETZEL, R.,AND LUTHER, M.  (I. G. Farbenindustrie A. G.).  [Organic Compounds Containing Oxygen.]  German Patent 628,557, Apr. 7, 1936 (Cl. 12 o-5.01).  Chem. Abs., vol. 30, 1936, p. 6005.

High-molecular alcohols are obtained by passing oxides of C over contact masses containing a greater amount of hydrating than hydrogenating catalyst.  Thus, a contact mass containing CdCrO₃ is heated and CO and H₂ passed over at 200 atm.  At 420°, MeOH is the chief product.  At 250°, with a reduction in the amount of H₂ used, a mixture of alcohols, ketones, esters, and acids is obtained.  Instead of CdCrO₄, MnO₂, Cu₃(NO₄)₂, PbMoO₄, Ag aluminate, or mixtures of the corresponding oxides may be used as the hydrating catalyst.
