Zusatz zum Patent No. 39313 vom 25. Juli 1886.Addition to patent no. 39313 of July 25, 1886.
Patentirt im Deutschen Reiche vom 10. Mai 1887 ab. Längste Dauer: 24. Juli 1901.Patented in the German Empire on May 10, 1887. Longest duration: July 24, 1901.
Vorliegende Erfindung betrifft einige Neuerungen an dem durch das D. R. P. No. 39313 geschützten Element, durch welche die Diffusion der beiden Flüssigkeiten verhindert bezw. sehr erschwert wird, ohne die osmotische Thätigkeit der bei geschlossenem Strom entstehenden Gase zu hindern, so dafs also eine gegenseitige Neutralisation möglichst vermieden und die Stromstärke möglichst constant erhalten wird.The present invention relates to several innovations in the method proposed by the D. R. P. No. 39313 protected element, through which the diffusion of the two liquids prevents BEZW. is made very difficult without the osmotic action of that which arises when the stream is closed To prevent gases, so that mutual neutralization is avoided as much as possible and the current strength is kept as constant as possible.
Eine Reihe von Versuchen, welche mit dem genannten Elemente unter Ersatz einzelner Theile desselben durch andere Stoffe angestellt wurden, hat ergeben, dafs diese Diffusion in bedeutendem Mafse eingeschränkt bezw. fast vollständig verhindert werden kann, wenn man statt des Kupferchlorids Kupfernitrat und statt der Salzsäure in diesem Falle Salpetersäure anwendet. A series of attempts, which with the named elements with replacement of individual Parts of it were caused by other substances, has shown that this diffusion in significant measure restricted resp. can be almost completely prevented if one uses copper nitrate instead of copper chloride and, in this case, nitric acid instead of hydrochloric acid.
Bei dieser Einrichtung des Elementes findet die osmotische Thätigkeit der Gase ihren Fortgang, selbst wenn die poröse Zelle infolge der Einwirkung der Säure auf das Alkali nur noch neutrale Salzlösung enthält.With this arrangement of the element the osmotic activity of the gases finds its progress, even if the porous cell only remains as a result of the action of the acid on the alkali contains neutral saline solution.
Ein derartiges Element kann folgendermafsen zusammengestellt werden:Such an element can be put together as follows:
Die zweckmäfsig amalgamirte Zinkelektrode wird in dem äufseren Gefäfs aus Glas oder einem anderen geeigneten Material, welches eine Lösung eines Aetzalkalis, z. B. von Aetznatron, enthält, die Kohlenelektrode dagegen in einem inneren, aus einer porösen Zelle gebildeten Gefäfs angeordnet, welches eine Mischung von Salpetersäure mit Kupfernitratlösung enthält.The appropriately amalgamated zinc electrode is placed in the outer vessel made of glass or another suitable material which is a solution of a caustic alkali, e.g. B. of caustic soda, contains, the carbon electrode, however, in an inner, formed from a porous cell Arranged vessel containing a mixture of nitric acid with copper nitrate solution contains.
Natürlich kann die Anordnung auch umgekehrt getroffen sein, so dafs sich das Zink mit der Aetzalkalilösung in der porösen Zelle und die Kohle mit der salpetersauren Kupfernitratlösung im Aufsengefäfs befindet. Die poröse Zelle ist immer innerhalb des äufseren Gefäfses angeordnet.Of course, the arrangement can also be made the other way round, so that the zinc moves with it the caustic alkali solution in the porous cell and the carbon with the nitric acid copper nitrate solution is in the cauldron. The porous cell is always inside the outer vessel arranged.
Für ein solches Element kann man zweckmäfsig die amalgamirte Zinkelektrode in eine Aetznatronlauge von 400 B., welche sich in dem äufseren Glasgefäfs befindet, tauchen, während man in die die Kohlenelektrode enthaltende poröse Zelle eine Flüssigkeit einfüllt, welche aus zwei Theilen Salpetersäure von 350B. und einem Theil einer Kupfernitratlösung von 350B. besteht.For such an element can be zweckmäfsig the amalgamated zinc electrode in a caustic soda of 40 0 for example, which is located in the outward glass vessel, diving, while in the carbon electrode containing porous cell is a liquid fills, consisting of two parts of nitric acid of 35 0 B. and a part of a copper nitrate solution of 35 0 B. consists.
Ein in dieser Weise zusammengesetztes Element zeigte am Anfang eine elektromotorische Kraft von 2,5 Volts und, nachdem die Elektroden durch einen kurzen Schliefsungsbogen 264 Stunden mit einander leitend. verbunden gewesen waren, noch eine solche von 2,4 Volts.An element assembled in this way initially exhibited an electromotive force Force of 2.5 volts and after the electrodes through a short arc of closure Conducting 264 hours with each other. had been connected, another one of 2.4 volts.
An Stelle der Salpetersäure und des Kupfernitrats kann man auch Schwefelsäure und Kupfersulfat nehmen. Jedoch mufs hierbei bemerkt werden, dafs durch Schwefelsäure und Kupfersulfat allein eine Ablagerung yon Kupfer auf der Kohlenelektrode nicht verhindert wird. Zu diesem Zwecke ist die Gegenwart von SaI-Instead of nitric acid and copper nitrate, one can also use sulfuric acid and Take copper sulfate. However, it must be noted here that by sulfuric acid and Copper sulphate alone does not prevent copper from being deposited on the carbon electrode. For this purpose, the presence of SaI-
petersäure nothwendig. Aus diesem Grunde wird es sich meistens bei Anwendung von Kupfersulfat empfehlen, nicht Schwefelsäure allein, sondern Schwefelsäure und Salpetersäure oder Salpetersäure allein zu benutzen.pitric acid necessary. For this reason, it will mostly be when using We recommend copper sulfate, not sulfuric acid alone, but sulfuric acid and nitric acid or to use nitric acid alone.
