Description
Ein technisch brauchbares Verfahren zur Darstellung von Zinknatriumsulfat ist nicht bekannt. Auskristallisieren von Natriumsulfat-Zinksulfatlösungen führt zu ganz verschiedenen Resultaten.A technically viable process for the preparation of zinc sodium sulfate is not known. Crystallization of sodium sulfate-zinc sulfate solutions leads to very different Results.
Es wurde nun die bemerkenswerte Beobachtung gemacht, daß aus Lösungen von Natriumsulfat und Zinksulfat durch Bisulfat das Doppelsalz von der Zusammensetzung ίο Na2SO4, ZnSO4, 4 H2 O ausgefällt wird.The remarkable observation has now been made that the double salt of the composition ίο Na 2 SO 4 , ZnSO 4 , 4 H 2 O is precipitated from solutions of sodium sulfate and zinc sulfate by bisulfate.
Zur technischen Darstellung des Salzes werden zweckmäßig zinkhaltige Materialien in der Wärme in konzentrierter Natriumbisulfatlösung bis zur Neutralität gelöst. Aus der nitrierten ,Lösung scheidet ein Zusatz von Bisulfat das • erwähnte Zinknatriumsulfat aus. In den Mutterlaugen kann man von neuem Zink lösen und den Prozeß wiederholen. Das Doppelsalz kann auch dadurch hergestellt werden, daß man Lösungen von Zinksulfat mit zweckmäßig gleichmolekularen Mengen Natriumsulfat versetzt und den gegebenenfalls genügend eingedampften Lösungen Bisulfat zufügt. Das Doppelsalz soll an Stelle des Zinksulfats verwendet werden.For the technical preparation of the salt, it is advisable to use zinc-containing materials in the Heat dissolved in concentrated sodium bisulfate solution until neutral. From the nitrided In solution, an addition of bisulphate eliminates the • mentioned zinc sodium sulphate. In the mother liquor you can dissolve the zinc again and repeat the process. The double salt can also be prepared by Solutions of zinc sulphate are mixed with appropriately equal molecular amounts of sodium sulphate and add bisulfate to the solutions which have been sufficiently evaporated if necessary. The double salt should can be used in place of the zinc sulfate.
