Description
Verfahren zum Reinigen von mit organischen Nitrokörpern durchsetztem Perchlorat. Das bei der Entleerung von Perchlorat-Munition anfallende Perohlorat ist stark -mit organischen Nitroköpern, namentlich Dinitroben.zol, verunreinigt (etwa 3 bis 5 Prozent).Process for cleaning of contaminated with organic nitro bodies Perchlorate. The perchlorate produced when emptying perchlorate ammunition is heavily contaminated with organic nitro compounds, namely dinitrobenzene (about 3 to 5 percent).
In diesem Zustande ist das Perchlorat für weitere Verwendung uribrauchbar. Namentlich für die Verwendung als Sprengstoffkomponente ist es erforderlich, daß derGehalt an Dinitrobenzol auf unter 1,5 Prozent herabgesetzt wird. Diese Reinigung ist nun aber infolge -der Wasserlöslichkeit des Bizolsbisher nur sehr umständlich und, teuer auf dem Extraktionswege durchzuführen gewesen.In this condition the perchlorate can be used for further use. In particular for use as an explosive component, it is necessary that the dinitrobenzene content is reduced to below 1.5 percent. This purification is now, however, due to the water solubility of the Bizol so far only very cumbersome and has been expensive to perform by the extraction route.
Es wurde nun gefundene, @daß eine solche Reinigung auch auf einfachere Weise erzielt werden kann., wenn man den Umstand ausnutzt, -daß das Perchlorat und die Hauptmenge des Dinitrobenzols zwar in innigem Gemisch und auch aneinander haftend, aber in getrenntem Vorhandensein, -der einzelnen Kristalle als solche in dem anfallenden Produkt enthalten und d'aß außerdem die großen. Perchloratkristalle schwerer als die feinen Dinitrobenzolnadeln sind. Es gelingt daher durch geeignete Behandlung, z. B. durch Schwemmen mit Wasser, ein Perchlorat zu gewinnen, das zur Weiterverarbeitung z. B. als Sprengstoffkomponente geeignet ist. Um Materialverluste zu vermeiden, wird zweckmäßig anstatt Wasser zu solcher Behandlung eine Flüssigkeit gewählt, !die Perchlorat nicht löst. Ausführungsbeispiel Unreines Perchlorat wird vermittels kalter, gesättigter wäßrigerPerchlöratlösung über eine kaska-denförmi-ge Schwemmvorrichtung gespült. Die Perchloratkristalle trennen sich dabei von Aden Dinitro#benzolnadeln. Letztere werden in einem Filter nebst einem Teil Perchloratstaubes .aufgefangen und in die Anlage zur .Gewinnung .-des unreinen Perchlorats zuriückgeleitet, während die Lauge zum Schwemmen weiterer' Mengen wieder verwendet wird. PATENT-ANSPRUCFI: It has now been found that such a purification can also be achieved in a simpler way, if one takes advantage of the fact that the perchlorate and the majority of the dinitrobenzene are in an intimate mixture and also adhere to one another, but in separate presence, -der contained individual crystals as such in the resulting product and also the large ones. Perchlorate crystals are heavier than the fine dinitrobenzene needles. It is therefore possible by appropriate treatment, for. B. by flooding with water to gain a perchlorate that can be used for further processing z. B. is suitable as an explosive component. In order to avoid material losses, it is advisable to use a liquid instead of water for this type of treatment, which does not dissolve perchlorate. Exemplary embodiment Impure perchlorate is flushed using cold, saturated aqueous perchlorate solution over a cascade-shaped washing device. The perchlorate crystals separate from the Aden Dinitro benzene needles. The latter are collected in a filter along with part of the perchlorate dust and fed back into the plant for the "recovery" of the impure perchlorate, while the lye is used again to wash away additional quantities.
