Description
Verfahren zur Darstellung eines Nickelkatalysators. Im Hauptpatent<B>123728</B> ist ein Verfahren zur Darstellung eines hochwirksamen Nickel- katalysators beansprucht, das dadurch gekenn zeichnet ist, dass man aus ammoniakalischen Nickelsalzlösungen in der Wärme und in Gegenwart eines Trägers durch einen Gas strom Nickelhydroxyd in kristalliner Form abscheidet und hierauf das auf dem Träger niedergeschlagene Nickelhydroxyd bei Tem peraturen von 450 und darüber mit Wasser stoff behandelt.
Gegenstand dieses Zusatzpatentes ist ein Verfahren zur Darstellung eines hochwirk samen Nickelkatalysators, das dadurch ge kennzeichnet ist, dass man aus einer Nickel salzlösung in der Wärme und in Gegenwart eines Trägers durch ein Alkalikarbonat Nik- kelkarbonat in kristalliner Form ausfällt und hierauf das auf dem Träger niedergeschlagene Nickelkarbonat bei Temperaturen von 450 und darüber mit Wasserstoff behandelt.
<I>Beispiel</I> 290 Gewichtsteile Nickelnitrat werden in 1000 Teilen Wasser gelöst und 50 Gewichtsteile Kieselsäuregel zugegeben. Das Gemisch wird auf 70 angewärmt und unter Rühren inner halb 8 Stunden 106 Gewichtsteile Soda ge löst in 3000 Teilen Wasser zutropfen gelassen. Der gebildete Niederschlag wird abgesaugt, nitratfrei gewaschen und bei etwa 100 ge trocknet.
70 Gewichtsteile des so erhaltenen Pulvers werden in ein weites Reduktionsrohr eingefüllt. Dieses wird unter Durchleiten eines lang samen Wasserstoffstromes zunächst auf 100 bis 130 . angeheizt. Wenn kein Wasserdampf mehr entweicht, geht man im Verlauf von 5-6 Stunden allmählich auf 500 . Bei dieser Temperatur bleibt man so lange, bis sich keine Wasserbildung mehr nachweisen lässt. Ist dies der Fall, so wird das Rohr rasch abgekühlt und der Katalysator im Wasser stoffstrom in ein passendes Suspensionsmittel wie Wasser, Pyridin, Dekalin eingegossen. Er stellt eine tiefschwarze, äusserst feinflockige, sich nur schwer absetzende Substanz dar.
Er bildet bei der Behandlung mit Wasserstoff und Sauerstoff in der Kälte Wasser und re duziert Acetonitril in Gegenwart von Wasser- stoff bei einer Temperatur von ungefähr 70 bis 80 zu Äthylamin.
Method for the preparation of a nickel catalyst. The main patent <B> 123728 </B> claims a process for the preparation of a highly effective nickel catalyst, which is characterized in that nickel hydroxide is deposited in crystalline form from ammoniacal nickel salt solutions in the heat and in the presence of a carrier through a gas stream and then the nickel hydroxide deposited on the carrier is treated with hydrogen at temperatures of 450 and above.
The subject of this additional patent is a process for the preparation of a highly effective seeded nickel catalyst, which is characterized in that one precipitates from a nickel salt solution in the heat and in the presence of a carrier by means of an alkali metal carbonate in crystalline form and then that precipitated on the carrier Nickel carbonate treated with hydrogen at temperatures of 450 and above.
<I> Example </I> 290 parts by weight of nickel nitrate are dissolved in 1000 parts of water and 50 parts by weight of silica gel are added. The mixture is warmed to 70 and, while stirring, 106 parts by weight of soda dissolved in 3000 parts of water are added dropwise within 8 hours. The precipitate formed is filtered off with suction, washed free of nitrates and dried at about 100.
70 parts by weight of the powder obtained in this way are poured into a wide reduction tube. This is initially increased to 100 to 130 while a slow stream of hydrogen is passed through. fueled. When no more water vapor escapes, gradually increase to 500 over the course of 5-6 hours. One stays at this temperature until no more water formation can be detected. If this is the case, the tube is quickly cooled and the catalyst is poured into a suitable suspension medium such as water, pyridine or decalin in the hydrogen stream. It is a deep black, extremely fine, flaky substance that is difficult to settle.
When treated with hydrogen and oxygen, it forms water in the cold and reduces acetonitrile in the presence of hydrogen at a temperature of about 70 to 80 to ethylamine.
