Description
In neuerer Zeit sind weitgehende Versuche dahingehend angestellt worden, Nitrozellulose-Nitroglyzerinpulver, welche bisher nur unter Zuhilfenahme größerer Mengen flüchtiger Lösemittel hergestellt werden konnten, deren Entfernung aus den fertiggestellten Pulverelementen schwierig und zeitraubend war, nunmehr ohne Verwendung flüchtiger Lösemittel unter Zuhilfenahme von nicht flüchtigen, inIn recent times, extensive attempts have been made to produce nitrocellulose-nitroglycerin powder, which up to now could only be produced with the help of larger amounts of volatile solvents, their removal from the finished powder elements was difficult and time consuming, now without the use of volatile solvents with the help of non-volatile, in
ίο der Pulvermasse verbleibenden, gelatinierend wirkenden Lösemitteln oder auch gänzlich ohne Benutzung von Lösemitteln herzustellen.ίο the powder mass remaining, gelatinizing active solvents or completely without the use of solvents.
Bei der Fabrikation derartiger PulvermassenIn the manufacture of such powder masses
ohne flüchtige oder ohne nichtflüchtige Lösemittel hat sich nun gezeigt, daß infolge der bei der Herstellung zu verwendenden hohen Temperaturen saure gasförmige Produkte entstehen können, deren Neutralisation noch während des Fabrikationsganges von größter Bedeutung für die spätere Stabilität des fertigen Produktes ist.Without volatile or without non-volatile solvents it has now been shown that as a result of the acidic gaseous products are formed in the production of the high temperatures to be used can, whose neutralization during the manufacturing process is of the greatest importance for the later stability of the finished product Product is.
Es wurde nun gefunden, daß durch einen geringen Zusatz von Ammoniumdoppelsalzen, wie z. B. Natriumammoniumoxalat, die Beseitigung dieser sauren Produkte trotz der hohen Temperatur während des Fabrikationsganges gelingt, und daß nach Fertigstellung Pulver von hoher .Stabilität erhalten werden können.It has now been found that by adding a small amount of ammonium double salts, such as B. Sodium ammonium oxalate, eliminating these acidic products in spite of the high temperature during the manufacturing process succeeds, and that after completion Powders of high stability can be obtained.
Als Beispiel sei angegeben:The following is given as an example:
25 Prozent Nitroglyzerin, 74 Prozent Nitrozellulose, ι Prozent Natriumammoniumoxalat werden nach mechanischer Knetung bei Temperaturen um 85 bis 95° herum gewalzt und bei derselben Temperatur je nach Abmessung der Pulverkörper unter einem Druck von 150 bis 700 Atm. zu Röhren gepreßt.25 percent nitroglycerin, 74 percent nitrocellulose, ι percent sodium ammonium oxalate are rolled after mechanical kneading at temperatures around 85 to 95 ° and at the same temperature depending on the dimensions of the powder body under a pressure of 150 up to 700 atm. pressed into tubes.
