Verfahren zum Reinigen von Sole von Magnesium- und Calziumsalzen für den Betrieb von elektrolytischen Zellen.
Für den Betrieb von elektrolytischen Zellen ist zwecks Vermeidung von Betriebsstörungen eine Sole yon hohem Reinheitsgrade erforderlich. Insbesondere wirkt die Gegenwart von Magnesium-und Calziumsalzen selbst in geringen Mengen bei der kontinuierlich arbeitenden Amalgamzelle überaus störend, indem durch die Zirkulation der Sole zwischen Zelle und Sättigungsvorrichtung im Queeksilber Magnesium und Calzium als Amalgame sich anreichern und dadurch zur Wasserstoffentwicklung Veranlassung geben und durch Verunreinigung des Quecksilbers den Betrieb gefährden. Die üblichen Methoden zur Reinigung von Sole durch Fällen mit Natriumkarbonat,-oxalat oder-phosphat erfordern in diesem Falle einen erheblichen Aufwand an diesen Fällungsmitteln, denn die Betriebssole ist mit Chlor gesättigt und weist saure Reaktion auf.
Es hat sich nun gezeigt, dass durch Sättigen der Sole mit Fluornatrium Magnesium-und Calziumsalze quantitativ ausgefällt werden, wobei saure Reaktion sowie Chlorgehalt der Sole ohne Einfluss auf die Vollständigkeit der Fällung sind. Die geringen, dabei in Lösung gehenden Mengen, zirka l Voo, Fluornatrium beeinträchtigen den Gang der Zelle nicht.

Process for purifying brine from magnesium and calcium salts for the operation of electrolytic cells.
For the operation of electrolytic cells, a brine of a high degree of purity is required in order to avoid operational disturbances. In particular, the presence of magnesium and calcium salts, even in small amounts, has an extremely disruptive effect in the continuously operating amalgam cell, in that the circulation of the brine between the cell and the saturation device in the queek silver causes magnesium and calcium to accumulate as amalgams, thereby giving rise to hydrogen development and contamination of the Mercury endanger operation. The usual methods of purifying brine by precipitating it with sodium carbonate, oxalate or phosphate in this case require a considerable amount of these precipitating agents, because the operational brine is saturated with chlorine and has an acidic reaction.
It has now been shown that by saturating the brine with fluorosodium magnesium and calcium salts are precipitated quantitatively, the acidic reaction and the chlorine content of the brine having no effect on the completeness of the precipitation. The small quantities of sodium fluoride, which go into solution, do not impair the functioning of the cell.
