Die Erfindung bezieht sich auf ein Waschverfahren von Trimethylen-Trinitramin (Hexogen) und besteht darin, daß man das in bekannter Weise gewonnene Roherzeugnis in Wasser aufschlämmt und durch einen oder mehrere mit Dampf betriebene Injektoren hindurchtreibt.The invention relates to a washing process of trimethylene trinitramine (hexogen) and consists in slurrying the raw product obtained in a known manner in water and propels through one or more steam powered injectors.
Die Stabilisierung von Nitrokörpern bereitet bekanntlich der Technik große Schwierigkeiten. Vielfach führt man den Waschprozeß bei erhöhter Temperatur durch Behandlung mit Wasser in Druckgefäßen durch. Derartige Arbeitsweisen erfordern einmal große Flüssigkeitsmengen und sind nicht einfach in bezug auf die Apparatur.The stabilization of nitro bodies is known to cause great difficulties in technology. Multiple one leads the washing process at elevated temperature by treatment with water in Pressure vessels through. Such procedures require and are once large amounts of liquid not simply in terms of equipment.
Es ist ein kontinuierliches Verfahren zum Waschen von flüssigen Salpetersäureestern, insbesondere Nitroglycerin, bekannt, nach dem diese flüssigen Sprengstoffe in Mischkammern mit der Waschflüssigkeit ohne Luftzufuhr vorgemischt und mittels Luftinjektoren durch mehrere Waschkolonnen getrieben werden, wobei in zwischengeschalte- ao ten Separatoren eine Trennung von flüssigem Sprengstoff und Waschmittel erfolgt. Der gereinigte Sprengstoff wird dann von dem letzten Separator mittels eines mit Wasser gespeisten Transportinjektors in das Lagerhaus befördert.It is a continuous process for washing liquid nitric acid esters, in particular Nitroglycerin, known after these liquid explosives in mixing chambers with the Wash liquid premixed without air supply and through several wash columns by means of air injectors be driven, with a separation of liquid in intermediate separators Explosives and detergent is made. The cleaned explosives are then removed from the final separator transported into the warehouse by means of a water-fed transport injector.
In sinngemäßer Anwendung dieses bekannten Verfahrens wurde auch schon Trinitrotoluol mit geeigneten Waschmitteln gereinigt, jedoch mußte hierbei das zu waschende Trinitrotoluol vorher durch Schmelzen in den flüssigen Zustand übergeführt und die Reinigung bei diesen flüssigen Zustand aufrechterhaltenden Temperaturen durchgeführt werden.In analogous application of this known process, trinitrotoluene was also used Suitable detergents cleaned, but the trinitrotoluene to be washed had to be cleaned beforehand converted into the liquid state by melting and the purification in this liquid state maintained temperatures are carried out.
Das Arbeiten mit geschmolzenen Sprengstoffen birgt gewisse Gefahren in sich, obwohl zu erwarten war, daß der flüssige Zustand des zu waschendenWorking with molten explosives involves certain dangers, although to be expected was that the liquid state of the thing to be washed

Sprengstoffes in kurzer Zeit einen guten Reinigungseffekt ergeben wird, so daß es nicht allgemein auf feste Sprengstoffe angewandt werden kann.Explosives will give a good cleaning effect in a short time, so it is not general can be applied to solid explosives.
Überraschenderweise wurde nun gefunden, daß Trimethylen-Trinitramin in festem Zustand von der ihm anhaftenden Salpetersäure in kurzer Zeit sehr weitgehend gereinigt und auch stabilisiert werden kann, wenn dieser Sprengstoff mit Wasser aufgeschlämmt und diese Trübe sodann mitSurprisingly, it has now been found that trimethylene trinitramine in the solid state of the nitric acid adhering to it is very largely cleaned and also stabilized in a short time can be if this explosive is slurried with water and this turbidity then with
ίο Wasserdampf durch einen oder mehrere mit Dampf betriebene Injektoren getrieben wird. Dabei kann man im Bedarfsfalle zwischen je zwei Injektoren eine Wasserabscheidung, etwa durch einen Cyklon, vorsehen und neues Waschwasser wieder hinzufügen. ίο water vapor through one or more with steam operated injectors is driven. If necessary, you can choose between two injectors Provide for water separation, for example by means of a cyclone, and add new washing water again.
Versuche haben gezeigt, daß aus der Nitrierung kommendes Roh-Hexogen durch eine Wäsche mit zwei Injektoren Erzeugnisse liefert, die im Minimum einen Abeltest von 30 Minuten bei einem Säuregehalt von 0,015 aufweisen.Experiments have shown that crude hexogen coming from the nitration can be washed with two injectors delivers products that require a minimum of 30 minutes for one Abel test Have an acidity of 0.015.
Die Verwendung von Dampfinjektoren ist erfindungswesentlich, denn nur so stabilisiert man gleichzeitig mit dem Waschen, ohne daß die Anwendung von Druck, also ein Arbeiten im Autoklav, notwendig wird. Durch die Behandlung des in Wasser suspendierten festen Sprengstoffes mit Dampfiujektoren zerfallen die einzelnen kristallinen Teilchen des Sprengstoffes, die in den intermizeilaren Hohlräumen vorhandene Säure kann freigesetzt und von dem Waschmittel aufgenommen werden. Die praktisch vollständige Stabilisierung tritt sehr schnell ein, während diese sonst nur durch längere Behandlung im Druckgefäß erzielt werden kann.The use of steam injectors is essential to the invention, because this is the only way to stabilize at the same time as washing, without the application pressure, i.e. working in an autoclave, becomes necessary. By treating the Solid explosives suspended in water with steam injectors disintegrate the individual crystallines Particles of the explosive that can cause acid in the intermixarial cavities released and absorbed by the detergent. The practically complete stabilization occurs very quickly, whereas this can otherwise only be achieved by prolonged treatment in the pressure vessel can.
