Description
Die Erfindung betrifft eine galvanische Primärzelle, die Quecksilber bzw. Quecksilbersalze und weitere Bestandteile zur Verminderung der Korrosion der Lösungselektrode enthält.The invention relates to a galvanic primary cell, the mercury or mercury salts and others Contains ingredients to reduce corrosion of the solution electrode.
Die bekannten Zellen dieser Art können keineswegs als korrosionsbeständig angesehen werden, wenn auch zahlreiche Bemühungen in dieser Richtung unternommen worden sind.The known cells of this type can by no means be regarded as corrosion-resistant, albeit numerous efforts in this direction have been made.
Bekanntlich ist die Korrosion entscheidend gemindert, wenn das Metall der Lösungselektrode sich in einem solchen Zustand befindet, daß es eine blanke Oberfläche besitzt. In dieser Richtung liegen daher auch die bisher bekanntgewordenen Versuche, eine korrosionsbeständige Zelle zu schaffen. Diese Versuche sind aber als praktisch nicht erfolgreich zu bezeichnen.It is known that corrosion is significantly reduced when the metal of the solution electrode is in is in such a state that it has a bare surface. Therefore lie in this direction also the previously known attempts to create a corrosion-resistant cell. These attempts but cannot be described as practically successful.
Der Erfindung liegt die Aufgabe zugrunde, neben Quecksilber bzw. Quecksilbersalzen solche Bestandteile in der Zelle zu verwenden, die gegebenenfalls im Zusammenwirken mit dem Quecksilber bzw. den Quecksilbersalzen während einer längeren Zeitdauer eine blanke Oberfläche des Metalls der Lösungselektrode aufrechterhalten, ohne daß hierdurch die Fabrikation der Zelle erschwert bzw. verteuert wird.The invention is based on the object, in addition to mercury or mercury salts, such constituents to use in the cell, possibly in interaction with the mercury or the Mercury salts leave a bare surface of the metal of the solution electrode for a long period of time maintained without making the manufacture of the cell difficult or expensive.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Primärzelle Thalliumsalze enthält. Durch die Anwendung von Thalliumsalzen ist es erstmals möglich geworden, die vorstehend angegebene Aufgabe zu lösen, so daß eine wesentliche Verminderung der Korrosion der Lösungselektrode auch über einen längeren Zeitraum zuverlässig erreicht wird.According to the invention, this object is achieved in that the primary cell contains thallium salts. By the use of thallium salts has made it possible for the first time to achieve the above-mentioned object to solve, so that a substantial reduction in the corrosion of the solution electrode also over a reliably achieved over a longer period of time.
Ein weiterer Vorteil der Erfindung ist darin zu erblicken, daß die Korrosion auch bei erhöhter Temperatur gemindert ist, so daß diese Zellen insbesondere auch in den Tropen gelagert und verwendet werden können.Another advantage of the invention can be seen in the fact that corrosion occurs even at elevated temperatures is reduced, so that these cells are stored and used in particular in the tropics can.
Wie durch Versuche festgestellt wurde, hat sich für die Verminderung der Korrosion Thalliumsulfat als besonders geeignet erwiesen.As has been established through experiments, thallium sulfate has been found to reduce corrosion proved particularly suitable.
Eine andere Ausführungsform der Erfindung besteht darin, daß wenigstens ein Teil der Thalliumsalze aus solchen mit großen organischen Anionen, insbesondere stickstoffhaltigen organischen Anionen, besteht. Solche Salze zeigen eine erhöhte inhibierende Wirkung und setzen demnach die Korrosion noch weiter herab. Thalliumsalze mit großen organischen Anionen sind beispielsweise Thalliumsalze der SuIf anilsäure, der Nikotinsäure, eines Kondensationsproduktes von Taurin (Aminoäthan-Sulfonsäure) mit einer Fettsäure u. dgl.Another embodiment of the invention is that at least some of the thallium salts consists of those with large organic anions, in particular nitrogen-containing organic anions. Such salts show an increased inhibiting effect and accordingly set the corrosion even more further down. Thallium salts with large organic anions are, for example, thallium salts of sulphonic acid, nicotinic acid, a condensation product of taurine (aminoethane sulfonic acid) with a Fatty acid and the like
Ein besonderer Vorteil der vorbeschriebenen Erfindung besteht darin, daß die Menge der für die Korrosionsverminderung notwendigen Thalliumsalze sehr gering sein kann. Die Erfindung ist deshalb auchA particular advantage of the invention described above is that the amount of for the Corrosion reduction necessary thallium salts can be very low. The invention is therefore also

darin zu erblicken, daß die Thalliumsalze am Gewicht der ganzen Zelle höchstens 2°/o ausmachen.to be seen in the fact that the thallium salts make up at most 2 per cent of the weight of the whole cell.
Diese geringe Menge an Thalliumsalz hat einen doppelten Vorteil: Zunächst fällt auf diese Weise der Preis des Thalliums praktisch nicht ins Gewicht; außerdem wird aber auch durch den geringen Zusatz an Thalliumsalzen der elektrochemische Vorgang in der Zelle praktisch nicht beeinflußt, so daß die Zelle ihre volle Kapazität und Leistungsfähigkeit behält.This small amount of thallium salt has a twofold advantage: First of all, this way the The price of thallium is practically negligible; in addition, however, is also due to the small addition of thallium salts has practically no effect on the electrochemical process in the cell, so that the cell retains its full capacity and efficiency.
Erfindungsgemäß können die korrosionsmindernden Thalliumsalze in einer galvanischen Primärzelle entweder im Außenelektrolyten oder im Depolarisator, vorzugsweise aber in beiden enthalten sein.According to the invention, the corrosion-reducing thallium salts in a galvanic primary cell can either be contained in the external electrolyte or in the depolarizer, but preferably in both.
Weiterhin können die korrosionsmindernden Thalliumsalze gelöst oder zum Teil in fester Form in der Zelle vorhanden sein.Furthermore, the corrosion-reducing thallium salts can be dissolved or partly in solid form in the Cell.
