Description

Verfahren zur Herstellung von Natriumazid Natriumazid wird nach der Synthese von Wislicenus aus Natriumamid und Stickoxydul dargestellt. In denn Patent 302 561 ist angegeben, daß die Reaktion zwischen Natriumamid und Stickoxydul sehr langsam verläuft. Dieses Patent sucht nun durch lebhafte Rührung und dauernde Zerkleinerung der festwerdenden Reaktionsmasse die Reaktionszeit abzukürzen. Der Zweck wird aber nur sehr unvollkommen erreicht, da die Reaktionsmasse anfangs flüssig ist, um später breiig und teigig zu werden.Process for the preparation of sodium azide Sodium azide is presented after the synthesis of Wislicenus from sodium amide and nitric oxide. Patent 302,561 states that the reaction between sodium amide and nitrogen oxide is very slow. This patent seeks to shorten the reaction time by stirring vigorously and continuously crushing the solidifying reaction mass. However, the purpose is only very imperfectly achieved, since the reaction mass is initially liquid, only to become mushy and doughy later.

Es wurde nun durch eingehende Versuche gefunden, daß man die Zeitdauer der Reaktion außerordentlich stark abkürzen kann, wenn man jeweils nur eine kleine Menge Natriumamid dem fertigen Umsetzungsprodukt, das aus äquivalenten Anteilen von Natriumazid und Ätznatron besteht, zusetzt. Zweckmäßig wird das aus viel Natriumazid und Ätznatron und wenig Natriumamid bestehende Gemisch hierbei gerührt oder in Bewegung gehalten. Es gelingt auf diese Weise; die Umsetzungszeit auf etwa den vierzigsten Teil der nach dem Verfahren des Patents 302 561: 1aenötigten Zeit abzukürzen. Diese überraschende Wirkung wird offenbar dadurch erreicht, daß dem Stickoxydul eine außerordentlich viel größere Oberfläche von Natriumamid dargeboten wird, weil sich das Amid in der pulverigen bis krümeligen Masse aufsaugt.It has now been found through extensive experiments that the duration of the reaction can be shortened extremely sharply if only a small amount of sodium amide is added to the finished reaction product, which consists of equivalent proportions of sodium azide and caustic soda. The mixture consisting of a lot of sodium azide and caustic soda and a little sodium amide is expediently stirred or kept in motion. It works this way; to shorten the implementation time to approximately one fortieth part of the time required by the method of patent 302 561: 1a. This surprising effect is apparently achieved in that the nitrogen oxide is presented with an extraordinarily much larger surface area of sodium amide, because the amide is absorbed in the powdery to crumbly mass.
