Description

Verfahren zur Beschleunigung der Abscheidung von Nitroglycerin Es ist bekannt, die Abscheidung des Nitroglycerins beim Nitrierprozeß dadurch zu beschleunigen, daß dem Gemisch Carbonate vor oder nach der beginnenden Nitrierung zugesetzt werden; auch hat man schon gegen Ende oder nach Beendigung der Nitrierung dem Gemisch Fluoride bzw. deren durch Säure leicht zersetzbare Salze zugefügt. Es ist ferner ein Verfahren zur Beschleunigung der Abscheidung des Nitroglycerins geschützt, bei dem vor der Nitrierung dem Glycerin und/oder dem Säuregemisch organische Verbindungen, welche durch die Einwirkung der Säure indifferente Gase entwickeln, z. B. Acetamid, Dicyandiamid oder Harstoff, zugesetzt werden.Method of accelerating the deposition of nitroglycerin Es it is known to accelerate the deposition of nitroglycerine during the nitration process by that carbonates are added to the mixture before or after the beginning of the nitration; one also has fluorides in the mixture towards the end or after the end of the nitration or their salts, which are easily decomposable by acid, are added. It is also a process to accelerate the deposition of the nitroglycerin protected, in which before the Nitration the glycerin and / or the acid mixture organic compounds, which develop inert gases due to the action of the acid, e.g. E.g. acetamide, dicyandiamide or urea, may be added.

Die vorliegende Erfindung betrifft ein Verfahren zur Beschleunigung der Abscheidung von Nitroglycerin, bei dem diese Beschleunigung ebenfalls durch Zusatz von Harnstoff, Dicyandiamid oder Acetamid herbeigeführt wird und diese Zusatzstoffe erst kurz vor oder nach Beendigung der Nitrierung zugesetzt werden, und zwar in der Weise, daß diese Stoffe vor dem Zusatz zu der Nitrocharge mit einer kleinen Menge Nitrier-oder Abfallsäure oder einer anderen geeigneten Säure aufgeschlämmt (verrührt, verteilt) werden. Auch zu bereits von der Hauptmenge des gebildeten Nitroglycerins getrennter Säure kann dieser Zusatz erfolgen.The present invention relates to a method for acceleration the deposition of nitroglycerin, in which this acceleration also occurs Addition of urea, dicyandiamide or acetamide is brought about and these additives be added shortly before or after the end of the nitration, namely in the way that these substances with a small before addition to the nitro charge Amount of nitrating or waste acid or other suitable acid slurried (stirred, distributed). Also to the majority of the nitroglycerin already formed This addition can be carried out using a separate acid.

Gegenüber dem Bekannten bietet die Erfindung wesentliche Vorteile, von denen folgende erwähnt seien. Erstens wird beim Zusatz nach der erfolgten Nitrierung der zugesetzte Stoff, der keineswegs billig ist, voll ausgenutzt, während nach den bekannten Verfahren ein Teil der aus dem zugesetzten Stoff entwickelten Gase mit der Rührluft weggeht. Der andere Vorteil besteht darin, d'aß -durch die Art des Zusatzes eine schnelle und gleichmäßige Verteilung der Stoffe in dem Flüssigkeitsgemisch gesichert ist. Setzt man die Stoffe nämlich nicht aufgeschlämmt zu, so lassen sie sich, da sie leicht sind, nur schwer verteilen, und es kann vorkommen, daß Teile davon an unkontrollierbaren Stellen der Apparatur sich festsetzen, was auf jeden Fall unerwünscht und eine Gefahrenquelle ist.Compared to the known, the invention offers significant advantages, of which the following may be mentioned. First, when adding after nitration has taken place the added substance, which is by no means cheap, is fully utilized while after the known processes with some of the gases developed from the added substance the stirring air goes away. The other advantage is that because of the nature of the In addition, a quick and even distribution of the substances in the liquid mixture is secured. If the substances are not added in a slurry, they leave Because they are light, they are difficult to distribute, and it can happen that parts of which get stuck in uncontrollable parts of the apparatus, something that affects everyone Case is undesirable and a source of danger.
