Description

  

  Verfahren zur Herstellung von wasserfreiem und     ozydfreiem        Zinkeblorid.            lin.    Hauptpatent ist ein Verfahren zur  Herstellung von wasserfreiem und     oxydfreiem          Magnesiumchlorid    aus     magnesiumoxydhaltigen          Stoffen    einerseits und gasförmigen,     chlorid-          bildenden    Mitteln anderseits beschrieben, bei  welchem man eine Suspension des Oxydes  in einer Schmelze von     Magnesiumchlorid    in  einem beheizten     Rieselturm    einem aufsteigen  den Strom des gasförmigen,

       chloridbildenden     Mittels entgegen     berabfliessen    lässt.  



  Es wurde nun gefunden, dass man diese       Bereitungsart    auch auf die Herstellung von  wasserfreiem und     oxydfreiem        Zirrkchlorid    an  wenden kann. Demgemäss lässt man vor  liegend eine Suspension von     Zinkoxyd    in  geschmolzenem Zinkchlorid in einem beheiz  ten     Rieselturm    einem aufsteigenden Strom  des gasförmigen,     chloridbildenden    Mittels ent  gegen herabfliessen.  



  Die     Ausfübrung    des Verfahrens kann er  folgen, wie im Hauptpatent beschrieben. Wie    dort für den Fall des Chlormagnesiums be  schrieben, so können auch hier als Aus  gangsstoffe solche wasserhaltige Chlorver  bindungen des Zinks dienen, welche beim  Entwässern durch Erhitzung einer Zersetzung  in Oxyd und Salzsäure unterliegen. Auch  kann dem     zinkoxydhaltigen    Stoff Kohlenstoff  in einer reaktionsfähigen Form beigemengt  werden und als     chloridbildendes    Mittel Chlor  Verwendung finden.



  Process for the production of anhydrous and ozyd-free zinc chloride. lin. Main patent describes a process for the production of anhydrous and oxide-free magnesium chloride from magnesium oxide-containing substances on the one hand and gaseous, chloride-forming agents on the other hand, in which a suspension of the oxide in a melt of magnesium chloride in a heated trickle tower with a rising flow of the gaseous,

       Chloride-forming agent can overflow against it.



  It has now been found that this type of preparation can also be used for the production of anhydrous and oxide-free cirrus chloride. Accordingly, a suspension of zinc oxide in molten zinc chloride is allowed to flow down in a heated trickle tower against an ascending stream of the gaseous, chloride-forming agent.



  The execution of the process can be followed as described in the main patent. As described there for the case of magnesium chloride, such water-containing chlorine compounds of zinc can also serve as starting materials, which are subject to decomposition into oxide and hydrochloric acid during dehydration by heating. Carbon can also be added to the substance containing zinc oxide in a reactive form and chlorine can be used as a chloride-forming agent.
