Description
Verfahren zur Herstellung von Cyannatrium. Die Erfindung bezieht sich auf die bekannte Herstellung von Cyannatrium aus Natriummetall, Kohle und Ammoniak. Bei diesem Verfahren werden beträchtliche Men gen von Wasserstoff frei, welche, da sie die Natrium-Metall-Cyannatriumschmelze bei sehr hohen Temperaturen passieren müssen, mit feinsten Staubteilchen beladen sind und ausserdem noch organische gasförmige Ver bindungen als Verunreinigungen enthalten. Dieser Wasserstoff wurde bisher in der Regel verloren gegeben, indem man ihn an der Luft verbrannte.
Nach der Erfindung wird dieser Wasser stoff für das Cyannatriumherstellungsver- fahren nutzbar gemacht. Es bat sich näm lich gezeigt, dass man den Wasserstoff mit verhältnismässig einfachen Mitteln in eine Form überführen kann, welche eine unmittel bare Weiterverarbeitung auf Ammoniak er möglicht, welch letzteres dann wieder in den Vorgang zurückgeführt und zur Herstellung von I\Tatriummetall benutzt wird.
In Ausübung der Erfindung kann man zum Beispiel derart verfahren, da,ss man den aus der Natrium-Metall-Cyannatrium- schm,elze abgehenden, verunreinigten Wasser stoff durch mit Wasser berieselte Kokstürme leitet und ihn alsdann der Trocknung unter wirft, was zum Beispiel durch Leiten durch Kalktürme geschehen kann.
Der so behan delte Wasserstoff kann nun unter Zusatz von Stickstoff, welcher auf billigem Wege, zum Beispiel aus der Luft, gewonnen wer den kann, durch Druckkatalyse in Ammo niak übergeführt werden, welch letzteres dann wieder mit Natriummetall und zum Beispiel Holzkohle in Reaktion gebracht wird.' Trotz der ausserordentlichen Einfach heit der erwähnten Reinigungsmethode mit Hilfe von Wasser verläuft die Überführung desselben in Ammoniak in glatter, störungs freier Weise. Es hat sich insbesondere ge zeigt, da-ss die bekanntlich ausserordentlich leicht vergiftbaren Kontakte nicht störend beeinflusst werden. .
An Stelle der Wasserbehandlung können gegebenenfalls auch andere einfache Reini gungsmethoden verwendet werden.
Die Nutzbarmachung des bisher verloren gegangenen Wasserstoffes im Kreislauf bie tet den ausserordentlichen Vorteil, dass nun mehr zur Herstellung von Cyannatrium nur noch Natriummetall neben billigem Luft stickstoff und billiger Kohle benötigt -wird. Der weittragende technische Fortschritt fällt ohne weiteres ins Auge, wenn man bedenkt.
d.ass die Cyanalkalifabriken bisher das ver flüssigte Ammoniak in Kesselwagen 'oder Bomben beziehen mussten, wobei noch zu be rücksichtigen ist, dass die Herstellung dieses Ammoniaks durch Druckkatalyse ein um ständliches und kostspieliges Verfahren zui Herstellung reinen Wasserstoffes zur Vor aussetzung hatte, welches das Vorhandensein einer besonders umfangreichen und raschem Verschleiss unterliegenden Apparatur er fordert.
Process for the production of cyan sodium. The invention relates to the known production of cyan sodium from sodium metal, coal and ammonia. In this process, considerable amounts of hydrogen are released, which, since they have to pass the sodium-metal-cyanosodium melt at very high temperatures, are loaded with extremely fine dust particles and also contain organic gaseous compounds as impurities. Up to now, this hydrogen has usually been lost by burning it in the air.
According to the invention, this hydrogen is made available for the cyan sodium production process. It has been shown that the hydrogen can be converted into a form with relatively simple means that enables immediate further processing on ammonia, which the latter is then returned to the process and used for the production of sodium metal.
In practicing the invention, one can proceed, for example, in such a way that the contaminated hydrogen leaving the sodium-metal-cyan-sodium melt is passed through coke towers sprinkled with water and then subjected to drying, which is done, for example Passing through lime towers can be done.
The hydrogen treated in this way can now be converted into ammonia by pressure catalysis with the addition of nitrogen, which can be obtained cheaply, for example from the air, and the latter is then reacted again with sodium metal and, for example, charcoal . ' Despite the extraordinary simplicity of the cleaning method mentioned with the aid of water, the conversion of the same to ammonia proceeds in a smooth, trouble-free manner. In particular, it has been shown that the known extremely easily poisonous contacts are not adversely affected. .
Instead of the water treatment, other simple cleaning methods can optionally also be used.
The utilization of the previously lost hydrogen in the cycle offers the extraordinary advantage that now only sodium metal is needed in addition to cheap air nitrogen and cheap coal to produce cyan sodium. The far-reaching technical progress immediately catches the eye when you think about it.
That is, the cyanalkali factories previously had to obtain the liquefied ammonia in tank cars or bombs, whereby it should also be taken into account that the production of this ammonia by pressure catalysis had to be a laborious and costly process for the production of pure hydrogen, which had to be available He demands a particularly extensive and rapid wear and tear of the apparatus.
