Description

Herstellung von Ammoniumazid Gegenstand des Patents 637 781 ist ein Verfahren zur Herstellung von Ammoniumazid, bei dem man Ammoniumclilorid mit Natriumazid in Gegenwart beschränkter Mengen Wasser erwärmt.Manufacture of Ammonium Azide Patent 637,781 relates to a process for the manufacture of ammonium azide, in which ammonium chloride is heated with sodium azide in the presence of limited amounts of water.

Bei der weiteren Ausbildung des Verfahrens wurde gefunden, daß man an Stelle von Ammoniumchlorid auch andere Ammoniumhalogenide (z. B. Ammoniumbromid) oder auch gesättigte Ammoniumsalze nicht flüchtiger Säuren ebenso vorteilhaft benutzen kann. Als Ammoniumsalze nicht flüchtiger Säuren kommen, insbesondere Ammoniumsulfat und sekundäres Ammoniumphosphat in Betracht. Die Umsetzungsbedingungen sind im allgemeinen dieselben wie die im Hauptpatent beschriebenen. Auch hier sind die Ausbeuten vorzüglich und entsprechen bei fortlaufendem Arbeiten den berechneten.In the further development of the process it was found that one Instead of ammonium chloride, other ammonium halides (e.g. ammonium bromide) or use saturated ammonium salts of non-volatile acids just as advantageously can. The ammonium salts of non-volatile acids come in particular, ammonium sulfate and secondary ammonium phosphate. The implementation conditions are in general the same as those described in the main patent. Here, too, the yields are excellent and correspond to the calculated ones if the work continues.

Beispiel In einem Glas- oder Porzellangefäß, das mit einem weiten absteigenden Kühler verbunden ist, erhitzt man ein inniges Gemenge von 13 Teilen Natriumazid, 15 Teilen Ammoniumsulfat und 2o Teilen Wasser, dem man etwas wäßriges Ammoniak zufügt, am besten in einem Ol_ oder Paraffmbad langsam bis auf 16o'. Dabei geht ein Gemisch. von Wasserdampf und dampfförmigem Ammoniumazid über. Im Kübler scheiden sich dabei etwa 7 Teile reines Ammoniumazid ab. Eine weitere Menge des Salzes erhält man beim Abkühlen der in der Vorlage angesammelten Flüssigkeit. Bei fortlaufendem Arbeiten auf die in dem Hauptpatent beschriebene Weise entspricht die Ausbeute etwa der berechneten.Example In a glass or porcelain vessel connected to a wide descending cooler, an intimate mixture of 13 parts of sodium azide, 15 parts of ammonium sulfate and 20 parts of water, to which a little aqueous ammonia is added, is best slowly heated in an oil or paraffin bath except for 16o '. There is a mixture here. of water vapor and vaporous ammonium azide. About 7 parts of pure ammonium azide are deposited in the Kübler. Another amount of salt is obtained when the liquid that has accumulated in the template cools down. If the work is continued in the manner described in the main patent, the yield corresponds approximately to that calculated.

Man kann auch hier das Verfahren auf die im Hauptpatent geschilderte Weise fortlaufend durchführen. An Stelle von Ammoniumsulfat kann man auch. die entsprechende Menge sekundäres Ammoniumphosphat oder eines Ammoniumsalzes einer anderen nicht flüchtigen Säure verwenden. Auch hierbei sorgt man durch Zusatz geringer Mengen von wäßrigem Ammoniak dafür, daß die Flüssigkeit nicht sauer wird.You can also use the procedure described in the main patent Manner continuously. Instead of ammonium sulfate you can also. the corresponding Amount of secondary ammonium phosphate or an ammonium salt of another does not use volatile acid. Here, too, one takes care of adding small amounts of aqueous ammonia to ensure that the liquid does not become acidic.

PATENTANSPRUCH. Weitere Ausbildung des Verfahrens zur Herstellung von Ammoniumazid gemäß Patent 637 781, dadurch gekennzeichnet, daß man an Stelle von Ammoniumchlorid andere Ammoniunibalogenide oder Ammoniumsalze nicht flüchtiger Säuren mit Natriumazid in Gegenwart beschränkter Mengen Wasser erwärmt. PATENT CLAIM. Further development of the process for the production of ammonium azide according to patent 637 781, characterized in that instead of ammonium chloride, other ammonium halides or ammonium salts of non-volatile acids are heated with sodium azide in the presence of limited amounts of water.
