Description

  

  Vorrichtung zur Umsetzung von Alkali- und     Erdalkaliamalgamen    behufs Herstellung  von Alkali- und     Erdalkalihydroxyden.       Es wurde gefunden, dass die Umsetzung  von Amalgamen mit Wasser behufs Her  stellung von Alkali- und     Erdalkalihydroxyden     dadurch erheblich beschleunigt werden kann,  dass man die zur Mischung des Amalgams  mit dem Wasser dienende     Rührvorrichtung     mindestens zu -einem überwiegenden Teil aus  elektrisch leitfähigem Kohlenstoff, wie Kohle,  Koks, Graphit     eto.    oder aus einer Vereini  gung dieser Stoffe untereinander herstellt,  zweckmässig in Verbindung mit einem Metall,  das durch Natronlauge und Amalgam nicht  angegriffen wird, zum Beispiel Metallegie  rungen aus Eisen,

   Chrom und Nickel als  Hauptbestandteile.  



  Zweckmässig gestaltet man die     Rührvor-          richtung    so aus, dass sie gleichzeitig zur Fort  bewegung des Amalgams durch die Zellen  und das Zersetzungsgefäss dienen kann; sie  hat dann den ganz erheblichen Vorteil einer  intensiven Berührung von Kohle mit Amal  gam und dem Wasser, ohne dass Störungen  im Betriebe der Apparatur auftreten können,  wie sie zum Beispiel stets bei Einrichtungen    stattfinden, in denen das     Fortbewegungsorgan     des Amalgams nur zu einem ganz geringen  Teil aus Kohle hergestellt ist.



  Device for the conversion of alkali and alkaline earth amalgams for the production of alkali and alkaline earth hydroxides. It has been found that the reaction of amalgams with water for the preparation of alkali and alkaline earth metal hydroxides can be accelerated considerably if the stirring device used to mix the amalgam with the water is at least largely made of electrically conductive carbon such as coal , Coke, graphite eto. or from a combination of these substances with one another, expediently in conjunction with a metal that is not attacked by caustic soda and amalgam, e.g. metal alloys made of iron

   Chromium and nickel as the main components.



  The stirring device is expediently designed in such a way that it can simultaneously serve to move the amalgam through the cells and the decomposition vessel; it then has the very considerable advantage of an intensive contact of coal with amalgam and the water, without the possibility of disturbances in the operation of the apparatus, such as always occur, for example, in facilities in which the amalgam's locomotive organ is only a very small part is made from coal.
