Description

_ Verfahren zur Darstellung von Hydrazin. Bei der Einwirkung von Teslaströmen, das sind Wechselströme von einer Frequenz von etwa i Million Schwingungen pro Sekunde, auf ein Gemisch von Stickstoff und Ammoniak glaubte F i n d 1 a v (Zeitschrift für Elektrochemie 12, S. 129) die Entstehung von Hydrazin nachgewiesen zu haben; sicher war er seiner Sache nicht. Wenn dieser zweifelhaften Beobachtung überhaupt etwas Tatsächliches zugrunde lag, war Hydrazin jedenfalls nur in Spuren entstanden; irgendwelche Bedeutung hat diese Reaktion nicht erlangt._ Process for the preparation of hydrazine. When exposed to Tesla currents, these are alternating currents with a frequency of about one million oscillations per second, on a mixture of nitrogen and ammonia believed F i n d 1 a v (journal for Elektrochemie 12, p. 129) to have demonstrated the formation of hydrazine; for sure he was not his thing. If this dubious observation anything at all In any case, hydrazine was only formed in traces; any This reaction has not achieved any significance.

Es hat sich nun gezeigt, daß man Ammoniak in guter Ausbeute in Hydrazin umwandeln kann, wenn man es den Entladungen hochgespannter Ströme von einer Frequenz, die unter ioo ooo Perioden liegt, aussetzt. Man benutzt hierbei vorteilhaft Spannungen zwischen 5ooo und 25 ooo Volt und arbeitet bei mäßigen oder niedrigen Temperaturen.It has now been shown that ammonia can be converted into hydrazine in good yield can convert, if one considers the discharges of high-voltage currents of a frequency, which is less than 100,000 periods. It is advantageous to use voltages here between 5,000 and 25,000 volts and operates at moderate or low temperatures.

Das Ammoniak kann man für sich oder in Mischung mit.Stickstoff oder anderen Gasen verwenden, hat aber dafür zu sorgen, daß die gebildeten Umwandlungsprodukte der Einwirkung der Entladungen baldmöglichst entzogen «-erden, damit kein Zerfall dieser Produkte, z. B. unter Bildung von Stickstoff, eintritt.The ammonia can be used on its own or in a mixture with nitrogen or use other gases, but must ensure that the conversion products formed withdrawn from the effect of the discharges as soon as possible, so that there is no disintegration of these products, e.g. B. with the formation of nitrogen occurs.

Um das gebildete Hydrazin aus dem Reaktionsraum möglichst rasch zu entfernen, arbeitet man zweckmäßig mit strömenden Gasen; man kann auch den Reaktionsraum mit Flüssigkeiten berieseln, die das Hydrazin aufnehmen und wegführen, ohne .dieses selbst nennenswert zu verändern; als solche Flüssigkeiten sind z. B. Paraffinöle und sonstige flüssige Paraffinkohlenwasserstoffe geeignet.In order to remove the hydrazine formed from the reaction chamber as quickly as possible remove, one works expediently with flowing gases; you can also use the reaction space sprinkle with liquids that absorb the hydrazine and carry it away without it to change significantly; as such liquids are e.g. B. paraffin oils and other liquid paraffin hydrocarbons are suitable.

Beispiel. Durch einen Ozoni.ätor bekannter Konstruktion, der mit Wasser gekühlt und mit einem Wechselstrom von 500 Perioden und io ooo Volt betrieben wird, leitet man gasförmiges, trockenes Ammoniak in lebhaftem Strom. Das den Apparat verlassende Gas wird kondensiert und aus dem so erhaltenen flüssigen Gemisch von Ammoniak und Hydrazin das Hydrazin durch Abdestillieren des Ammoniaks erhalten; es kann z. B. durch überführen in das Sulfat gereinigt werden.Example. An ozonator of known construction, which is cooled with water and operated with an alternating current of 500 periods and 100 volts, is used to conduct gaseous, dry ammonia in a lively current. The gas leaving the apparatus is condensed and the hydrazine is obtained from the liquid mixture of ammonia and hydrazine thus obtained by distilling off the ammonia; it can e.g. B. can be purified by converting it into the sulfate.
