Es hat sich gezeigt, daß bei der Verwendung oxydischer Kontaktmassen, die auch in reduzierender Atmosphäre nicht zu Metall reduziert werden, für die Ausführung organischer Katalysen, namentlich Hydrierungen, es besonders vorteilhaft ist, als Katalysatoren Gemische von Oxyden von Metallen verschiedener Gruppen des periodischen Systems und dabei das basischere Oxyd im ÜberschußIt has been shown that when using oxidic contact masses, which are also used in reducing atmosphere cannot be reduced to metal, for running organic Catalysts, namely hydrogenations, it is particularly advantageous as catalysts Mixtures of oxides of metals of different groups of the periodic table and the more basic oxide is in excess

Ähnlich verhält es sich mit den Kombinationen Zinkoxyd-Uranoxyd, Zinkoxyd-Vanadinoxyd, Zinkoxyd-Wolframoxyd, Magnesiumoxyd - Molybdänoxyd, Ceroxyd - Manganoxyd usw. Daneben können noch weitere Bestandteile, z. B. Metalle, hinzugefügt werden. Die Herstellung derartiger gemischter Kontaktmassen kann durch inniges Zusammenmischen der Bestandteile, durch gemeinsame Fällung aus Lösungen, Zusammenschmelzen geeigneter Salze oder in sonstiger Weise erfolgen.The situation is similar with the combinations zinc oxide-uranium oxide, zinc oxide-vanadium oxide, Zinc oxide-tungsten oxide, magnesium oxide - molybdenum oxide, cerium oxide - manganese oxide, etc. z. B. metals are added. The production of such mixed contact masses can be obtained by intimately mixing the constituents together, by joint precipitation Solutions, melting together of suitable salts or in any other way.
Die Ausführung der Hydrierung selbst kann bei Verwendung der Kontaktmassen in gewohnter Weise erfolgen. Besonders gute Ergebnisse liefern die vorstehend beschriebenen Kontaktmassen bei der Hydrierung von KohJenoxyd oder Kohlensäure mit Wasserstoff unter Druck zu Methylalkohol oder höher molekularen, sauerstoffhaltigen Verbindungen. The execution of the hydrogenation itself can when using the contact masses in in the usual way. Those described above give particularly good results Contact masses in the hydrogenation of carbon dioxide or carbonic acid with hydrogen under pressure to methyl alcohol or higher molecular, oxygen-containing compounds.
Ein eisenkarbonylfreies Gasgemisch von 45^ 30 Teilen Kohlenoxyd, 64 Teilen Wasserstoff, 4 Teilen Stickstoff, 1 Teil Methan und 1 Teil Kohlensäure wird unter einem Druck von 200 Atmosphären bei 4000 über eine Kontaktmasse geleitet, die durch Mischen von 90 Teilen Zinkoxyd und ι ο Teilen Chromsäure in feuchtem Zustande hergestellt und vor dem Gebrauch durch Überleiten des genannten Gasgemisches unter den erwähnten Bedingungen . in dem Kontaktofen selbst reduziert wurde. Die austretenden Reaktionsgase scheiden beim Abkühlen unter Druck reichliche Mengen fast reinen Methanols ab. Mit ähnlichem Erfolge verwendet man statt der obigen Kombination folgende Mischungen: 85 Teile Zinkoxyd, getränkt mit 15 Teilen Vanadiumnitrat oder 90 Teile Cadmium-An iron carbonyl-free gas mixture of 45 ^ 30 parts of carbon oxide, 64 parts of hydrogen, 4 parts of nitrogen, 1 part of methane and 1 part of carbonic acid is passed under a pressure of 200 atmospheres at 400 0 over a contact mass which, by mixing 90 parts of zinc oxide and ι ο Parts of chromic acid in the moist state and prepared before use by passing the gas mixture mentioned under the conditions mentioned. was reduced in the contact furnace itself. The emerging reaction gases separate copious amounts of almost pure methanol on cooling under pressure. The following mixtures are used with similar success instead of the above combination: 85 parts of zinc oxide, impregnated with 15 parts of vanadium nitrate or 90 parts of cadmium
