Description

Verfahren zur Herstellung von für die Reduktion oder Hydrierung organischer Verbindungen " geeigneten Katalysatoren In dem Hauptpatent 546828 wird ein Verfahren zur Herstellung von für die Reduktion oder Hydrierung organischer Verbindungen geeigneten, aus unedlen Metallen, wie Nickel, Kobalt, Kupfer oder ihren Gemischen, bestehenden Katalysatoren beschrieben, welches dadurch gekennzeichnet ist, daß man diese Metalle aus den wäßrigen Lösungen ihrer Salze in Gegen-,vart von Ammoniak durch Wasserstoff oder wasserstoffhaltige Gase bei Gegenwart oder Abwesenheit eines Trägers zur Abscheidung bringt.Process for the production of catalysts suitable for the reduction or hydrogenation of organic compounds The main patent 546828 describes a process for the production of catalysts suitable for the reduction or hydrogenation of organic compounds and consisting of base metals such as nickel, cobalt, copper or their mixtures , which is characterized in that these metals are brought to the deposition from the aqueous solutions of their salts in the presence of ammonia by means of hydrogen or hydrogen-containing gases in the presence or absence of a carrier.

Wie nun in weiterer Bearbeitung des Verfahrens gefunden wurde, kann man bei der Abscheidung durch Wasserstoff mit dem gleichen Erfolge an Stelle von Ammoniak organische Basen oder auch Säureamide anwenden. Die so erhaltenen Katalysatoren zeichnen sich durch die gleiche hohe Wirksamkeit bei der katalytischen Hydrierung und Reduktion organischer Verbindungen aus wie die Produkte des Hauptpatents.As has now been found in further processing of the procedure, can one with the deposition by hydrogen with the same success in place of Use ammonia, organic bases or acid amides. The catalysts thus obtained are characterized by the same high efficiency in catalytic hydrogenation and reduction of organic compounds like the products of the main patent.

Von den bekannten Verfahren zur Herstellung kolloider unedler Metalle durch Reduktion neutraler Lösungen organischer Metallverbindungen, besonders des Nickels, wie Nickelcarbonyl, Nickelformiat und Nickelacetat, vorzugsweise in Glycerinlösung, unterscheidet sich das vorliegende Verfahren dadurch, daß anorganische Metallsalze in Gegenwart von organischen Basen oder Säureamiden zu nicht kolloidalen Metallen reduziert werden. ' Beispiel toi Teile Nickelsulfat werden in 40o Teilen Wasser gelöst und mit izo Teilen Pyridin versetzt. Zu dieser Mischung gibt man, i i o Teile Kieselgur und a Teile feinverteiltes Nickel. Hierauf wird im Rührautoklaven bei etwa ioo° C und 30 bis 4o Atm. durch Wasserstoff das Metall auf dem Träger abgeschieden. Der Katalysator wird von der Flüssigkeit befreit und kann in feuchtem Zustande oder nach dem Trocknen für katalytische Reduktionen oder Hydrierungen verwendet werden.The present process does not differ from the known processes for the production of colloidal base metals by reducing neutral solutions of organic metal compounds, especially nickel, such as nickel carbonyl, nickel formate and nickel acetate, preferably in glycerol solution, in that inorganic metal salts are not present in the presence of organic bases or acid amides colloidal metals are reduced. For example, one part of nickel sulfate is dissolved in 40o parts of water and izo parts of pyridine are added. To this mixture are added iio parts of kieselguhr and a part of finely divided nickel. This is done in a stirred autoclave at about 100 ° C and 30 to 40 atm. the metal is deposited on the carrier by hydrogen. The catalyst is freed from the liquid and can be used in the moist state or after drying for catalytic reductions or hydrogenations.
