KLASSE 78 c. GRUPPECLASS 78 c. GROUP
in BERLIN.in Berlin.
Seit lange setzt man den rauchlosen Schießpulvern Körper zu, welche, ohne an sich ballistisch zu wirken, infolge ihres hohen Kohlenstoffgehalts geeignet sind, die Brisanz des Pulvers zu vermindern. Ein solcher Zusatzstoff ist beispielsweise die Vaseline. Mit den Fortschritten der modernen Fabrikation sind an derartige Zusätze noch weitere Forderungen gestellt worden, insbesondere soweit die Erhöhung der Stabilität, die Vermehrung der Plastizität usw. in Betracht kommt. Diesen Forderungen vermochte ein Körper wie die Vaseline nicht zu entsprechen. Man ist daher zu Estern aromatischer oder Fettsäuren übergegangen: Diamylphtalsäure-, Diamylbernsteinsäureester, Weinsäure- und Zitronensäureäthylester, Ester der Benzoesäure usw. Alle diese Körper haben infolge ihrer Eigenschaften, Nitrocellulose zu lösen, wohl die Fähigkeit, die Plastizität von rauchlosen Nitroglycerin- oder reinen Nitrocellulosepulvern zu erhöhen, es fehlt ihnen aber die Eigenschaft, stabilisierend zu wirken. Nach dem vorliegenden Verfahren werden dagegen Körper verwendet, welche gleichzeitig die Plastizität und die Stabilität der Pulvermasse erhöhen. Solche Verbindungen sind die Anilide organischer Säuren, in denen der Imidwasserstoff durch ein Radikal ersetzt ist, wie dies beispielsweise beim Methylbenzoylanilid und Äthylformanilid der Fall ist. Diese Anilide, ausgenommen solche, welche bei der Verseifung Essigsäure bzw. deren Homologen abzuspalten vermögen, wie Äthyloder Methylacetanilid, erhöhen die Stabilität der Pulver in ganz besonderem Grade, ohne selbst bei größerem Zusatz (5 bis 8 Prozent) die ballistische Leistung der Pulver so ungünstig zu beeinflussen, wie dies bei Vaseline und anderen Stoffen der Fall ist.For a long time, bodies have been added to smokeless gunpowder, which without being ballistic to act, due to their high carbon content, the explosive nature of the To reduce powder. Such an additive is, for example, petroleum jelly. With the Advances in modern manufacturing make additional demands on such additives been asked, especially as far as the increase in stability, the increase in Plasticity, etc. comes into consideration. A body like that could meet these demands Vaseline does not match. We have therefore switched to esters of aromatic or fatty acids: Diamylphthalic acid, diamylsuccinic acid ester, tartaric acid and citric acid ethyl ester, Esters of benzoic acid, etc. All of these bodies, owing to their properties of dissolving nitrocellulose, have the ability to dissolve the To increase the plasticity of smokeless nitroglycerin or pure nitrocellulose powders, it but they lack the property of having a stabilizing effect. According to the present proceedings on the other hand, bodies are used, which at the same time enhance the plasticity and the stability of the Increase powder mass. Such compounds are the anilides of organic acids in which the imide hydrogen is replaced by a radical, as is the case with methylbenzoylanilide, for example and ethylformanilide is the case. These anilides, with the exception of those which are acetic acid or their Able to split off homologues, such as ethyl or methylacetanilide, increase the stability the powder in a very special degree, without even with larger additions (5 to 8 percent) affect the ballistic performance of the powder as unfavorably as it does with petroleum jelly and other substances is the case.
Sehr gut eignen sich diese substituierten Anilide organischer Säuren wegen ihres großen Lösungsvermögens für Nitrocellulose und ihrer leichten Löslichkeit in Äther und Alkohol auch zum Ersatz des Kampfers in Nitrocellulosepulvern, wobei sie noch den Vorteil der geringeren Flüchtigkeit bieten, wodurch natürlich die Stabilität der Pulver gleichfalls günstig beeinflußt wird. . .These substituted anilides of organic acids are very suitable because of their large size Solvent power for nitrocellulose and its easy solubility in ether and alcohol also to replace the camphor in nitrocellulose powders, whereby they still have the advantage of the lower ones Offer volatility, which of course makes the stability of the powder equally favorable being affected. . .
