KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Bei der Elektrolyse der Chloralkalien unter Anwendung von Quecksilberkathoden wurde seither das gebildete Amalgam mit oder ohne Anwendung des elektrischen Stromes in Aetzalkali und Quecksilber zersetzt und das Quecksilber wieder in den Zersetzungsraum zurückgeführt. During the electrolysis of the chlor-alkalis with the application of mercury cathodes since then the amalgam formed with or without the application of electric current in caustic alkali and mercury decomposed and the mercury returned to the decomposition room.
Für die Zersetzung des Amalgams ohne Zuhülfenahme eines elektrischen Stromes wurden bis jetzt die verschiedensten und complicirtesten Verfahren und Vorrichtungen vorgeschlagen, die alle den Zweck verfolgten, das Amalgam mit sich stets erneuernder Oberfläche mit dem Wasser in Berührung zu bringen und zu zersetzen, da sich das Amalgam mit dem Wasser eben nur an der Berührungsstelle beider umsetzt. Die stete Erneuerung der Berührungsstelle hat bis heute selbst bei den vollkommensten zur Verfügung stehenden Vorrichtungen viel Zeit und, was wesentlich ist, sehr grofse Quecksilbermengen in Anspruch genommen.For the decomposition of the amalgam without the aid of an electric current up to now the most varied and most complex methods and devices have been proposed, which all pursued the purpose of combining the amalgam with the constantly renewing surface Bringing water into contact and decomposing, as the amalgam with the water only implemented at the point of contact between the two. The constant renewal of the point of contact has continued even today with the most perfect The devices available take up a great deal of time and, what is essential, very large quantities of mercury taken.
Das vorliegende Verfahren erreicht die Umsetzung in sehr kurzer Zeit und gestattet, mit wenig Quecksilber zu arbeiten. Es besteht darin, dafs man das Amalgam fein zerstäubt und es dadurch mit aufserordentlich grofser Oberfläche mit dem zersetzenden Agens in Berührung bringt.The present method achieves the implementation in a very short time and allows with little mercury to work. It consists in finely atomizing the amalgam and it thereby comes into contact with the decomposing agent with an extraordinarily large surface brings.
Dieses Agens, welches zugleich die Zerstäubung bewerkstelligt, kann Wasserdampf oder Druckluft, heifs oder kalt, oder ein Gemisch von Wasser, Dampf und Luft sein., This agent, which also manages the atomization, can be water vapor or Compressed air, hot or cold, or a mixture of water, steam and air.
Ein diesem Verfahren dienender Apparat kann so, wie in der beiliegenden Zeichnung dargestellt, construirt sein.Apparatus for this method can be as shown in the accompanying drawing to be represented, constructed.
In dieser Zeichnung ist α das elektrolytische Gefäfs, in welches die Anoden b eintauchen. Die Kathode wird von einer am Boden befindlichen Quecksilberschicht c gebildet. Diese Quecksilberschicht steht durch communicirende Rohre de mit einem Behälter/ in Verbindung. In das obere Ende des Rohres e mündet eine Dampf- oder Luftdüse g, welche das aus a nach / steigende Amalgam in dem Behälter / zerstäubt, derart, dafs die feinsten Amalgampartikelchen mit dem Dampf oder der Luft in innige Berührung kommen und rasch der Reaction unterliegen.In this drawing, α is the electrolytic vessel into which the anodes b are immersed. The cathode is formed by a mercury layer c on the bottom. This layer of mercury is carried communicirende de tubes with a container / in conjunction. A steam or air nozzle g opens into the upper end of the tube e , which atomizes the amalgam rising from a / in the container / in such a way that the finest amalgam particles come into intimate contact with the steam or air and are quickly subject to the reaction .
Durch Kühlrohre h werden die Reactionsproducte condensirt, die sich in dem Behälter/ sammeln. Das unten befindliche Quecksilber gelangt durch das Rohr i in den Behälter d zurück, während die darüber stehende Alkaliverbindung als Hydroxyd nach dem Sammelgefäfs k abläuft bezw. bei Verwendung von trockener Luft als Oxyd periodisch aus dem Reactionsraum entfernt wird.The reaction products which collect in the container / are condensed through cooling tubes h. The mercury below comes back through the tube i into the container d , while the alkali compound above it runs off as hydroxide after the collecting vessel k respectively. is periodically removed from the reaction chamber when dry air is used as the oxide.
Auf diese Weise wird im continuirlichen Betriebe das Quecksilber rasch und ohne Kosten von dem Alkalimetall geschieden und dieses in Form seines Oxyds bezw. Hydrats gewonnen.In this way the mercury becomes quickly and without in continuous operation Cost divorced from the alkali metal and this bezw in the form of its oxide. Hydrate won.
An Stelle von Luft und Wasser kann man auch andere Stoffe mit dem Amalgam zerstäuben, wenn solche im Stande sind, mit demInstead of air and water, other substances can also be atomized with the amalgam, if such are able with that
Alkalimetall Verbindungen einzugehen und es dadurch von dem Quecksilber zu trennen. So kann man das Amalgam mit absolutem Alkohol zerstäuben. Es scheidet sich dann das Alkalimetall als gelöstes Alkoholat ab. Bei entsprechendem Wassergehalt des Alkohols entsteht alkoholische Alkalilauge.To enter into alkali metal compounds and thereby separate it from the mercury. So the amalgam can be atomized with absolute alcohol. The alkali metal then separates as dissolved alcoholate. If the water content of the alcohol is appropriate, it is produced alcoholic alkali.
