Patentirt im Deutschen Reiche vom 9. November 1886 ab.Patented in the German Empire on November 9, 1886.
Es werden Lösungen aus 14 Theilen Aluminiumsulfat in 30 Theilen Wasser und 13 Theilen Ferrocyankalium in 52 Theilen Wasser bereitet. Die Lösungen werden gemischt, es entsteht ein Niederschlag von Ferrocyanaluminium und eirie Lösung von Kaliumsulfat; das Ferro cyan aluminium wird gesammelt und getrocknet.Solutions of 14 parts of aluminum sulphate are obtained in 30 parts of water and 13 parts of potassium ferrocyanide in 52 parts of water prepares. The solutions are mixed, a precipitate of ferrocyanic aluminum is formed and a solution of potassium sulfate; the ferro cyan aluminum is collected and dried.
Zur Darstellung des Ferrocyanmagnesiums werden Lösungen von 50 Theilen Magnesiumsulfat in 200 Theilen Wasser und 43 Theilen Ferrocyankalium in 180 Theilen Wasser auf dieselbe Weise zersetzt.Solutions of 50 parts of magnesium sulphate are used to prepare ferrocyanic magnesium in 200 parts of water and 43 parts of potassium ferrocyanide in 180 parts of water decomposed the same way.
Das Ferrocyankalium kann auch durch andere Ferrocyanverbindungen der Alkalien, sowie die Sulfate des Aluminiums und Magnesiums durch die Chlorverbindungen ersetzt werden.The ferrocyanic potassium can also be replaced by other ferrocyanic compounds of the alkalis, as well as the Sulphates of aluminum and magnesium are replaced by the chlorine compounds.
Aus den Ferrocyanverbindungen des Aluminiums und Magnesiums werden die Cyandoppelsalze
derselben mit den Alkalien auf folgende Weise dargestellt:
■ 75 Theile trockenes Ferro cyanaluminium werden mitThe cyan double salts of the ferrocyanic compounds of aluminum and magnesium are represented with the alkalis in the following way:
75 parts of dry ferrocyanic aluminum are mixed with
32 Theilen wasserfreiem Natriumcarbonat gemischt und unter möglichstem Luftabschlufs in Tiegeln oder Oefen geglüht.32 parts of anhydrous sodium carbonate mixed and with the possible exclusion of air Annealed in crucibles or ovens.
Das Cyaneisen der Verbindung wird hierdurch zerlegt. Kohlenstoffeisen wird abgeschieden und neben Natriumcyanat das Doppelsalz des Cyanaluminiums mit dem Cyannatrium (Cyanaluminiümcyannatrium:The cyan iron of the compound is thereby broken down. Carbon iron is deposited and in addition to sodium cyanate, the double salt of cyan aluminum with cyan sodium (cyan aluminum cyan sodium:
AP Cj-6 + 3 Na Cy)
als geschmolzene Masse erhalten, welche durch Abgiefsen von dem zu Boden gefallenen Kohlenstoffeisen
getrennt wird. AP Cj- 6 + 3 Na Cy)
obtained as a molten mass, which is separated from the fallen carbon iron by pouring.
Das Cyanmagnesiumcyannatrium wird auf dieselbe Weise durch Glühen vonThe cyanmagnesium cyanide is made in the same way by annealing
26 Theilen Ferrocyanmagnesium mit
11 - kohlensaurem Natrium
erhalten.26 parts of Ferrocyanmagnesium with
11 - Sodium carbonate
obtain.
An Stelle des Natriumcarbonats sind auch die Oxyde sowie die Carbonate anderer Alkalien zu verwenden.Instead of sodium carbonate are also to use the oxides as well as the carbonates of other alkalis.
Die Abscheidung von Aluminium und Magnesium aus ihren Cyandoppelsalzen erfolgt durch Schmelzen derselben mit Zink oder einem anderen in gleicher Weise wirkenden Metall.The separation of aluminum and magnesium from their cyan double salts takes place by melting them with zinc or another metal that acts in the same way.
2 Theile Cyanaluminiümcyannatrium werden mit2 parts of cyanaluminum cyanide are added
ι Theil Zink in bedecktem Tiegel oder Ofen geglüht;Part of zinc in a covered pan or furnace annealed;
es entstehen: das Cyandoppelsalz des Zinks mit Cyannatrium (Cyanzinkcyannatrium) als Schlacke, und Aluminium, welches als Regulus sich abscheidet. the result is: the cyan double salt of zinc with cyan sodium (cyan zinc cyan sodium) as slag, and aluminum, which is deposited as regulus.
Die Gewinnung des Magnesiums erfolgt auf dieselbe Weise aus dem Cyanmagnesiumcyannatrium. The extraction of the magnesium takes place in the same way from the cyanomagnesium cyanide.
Die Schlacke von Cyanzinkcyannatrium wird in Wasser gelöst, mit Eisen erwärmt, wodurch das Zink metallisch abgeschieden und Lösung von Ferrocyannatrium gebildet wird, mit welcher Aluminium- und Magnesiumsalze, zur Darstellung von Ferrocyanaluminium und Magnesium, zersetzt werden.The slag of cyanide zinc cyanide is dissolved in water, heated with iron, whereby the zinc is metallically deposited and a solution of ferrocyan sodium is formed, with which Aluminum and magnesium salts, for the preparation of ferrocyanal aluminum and magnesium, be decomposed.
Die Ferrocyanverbindungen des Aluminiums und Magnesiums können auch direct mit Aluminiumoxyd oder Magnesiumoxyd zusammengeschmolzen werden; in diesem Falle erhält man unter Abscheidung von Eisen die einfachen Cyanverbindungen, bei Zusatz von Cyanalkali die Doppelcyanverbindungen mit den Alkalien.The ferrocyanic compounds of aluminum and magnesium can also be used directly with aluminum oxide or magnesia melted together; in this case the simple ones are obtained with the deposition of iron Cyan compounds, with the addition of cyanide the double cyan compounds the alkalis.
