Description

HNHN
Die Schubkraft von Gasen, die bei einer chemischen Reaktion entstehen, wird in der Technik ausgenutzt, um z. B. bei Feuerlöschern, Flüssigkeiten oder Feststoffe aus einem Behälter auszutreiben. Andere Geräte verwenden diese Kraft, um Schieber oder Riegel zu betätigen oder andere Arbeit zu leisten, vergleiche z. B. deutsche Patentschrift 854 770, Einleitung.The thrust of gases that arise during a chemical reaction is used in technology, to z. B. in fire extinguishers to expel liquids or solids from a container. Other devices use this force to operate slides or bolts or to do other work, compare z. B. German Patent 854 770, introduction.
Als gaserzeugende Ladungen sind für diesen Zweck Stoffe oder Mischungen bekannt, die ganz oder zum größten Teil auf der Grundlage brennbarer, gas- und wärmeliefernder Stoffe aufgebaut sind. Solche Stoffe können ohne Sauerstoffzufuhr verbrennen, wie ζ. B. Nitrocellulosepulver oder Nitropolystyrol, oder aber sie bestehen aus Gemischen von sauerstoffliefernden Stoffen einerseits, wie z. B. Kaliumchlorat. und gasliefernden Stoffen andererseits, wie Ammoniumnitrat oder Guanidinnitrat; vergleiche z. B. deutsche Patentschriften 854 770. 851919 und 909 424. Auch Mischungen von gasliefernden Stoffen und flüssigen Brennstoffen, wobei als gasliefernde Stoffe !heterocyclische Ringverbindungen mit drei oder mehr Stickstoffatomen sowie deren Derivate und Salze genannt werden, sind durch die deutsche Patentschrift 977 699 bekannt.Substances or mixtures are known as gas-generating charges for this purpose, wholly or in part are mostly built on the basis of flammable, gas and heat-releasing substances. Such Substances can burn without the supply of oxygen, such as ζ. B. nitrocellulose powder or nitropolystyrene, or but they consist of mixtures of oxygen-supplying substances on the one hand, such as. B. Potassium Chlorate. and gas-producing substances on the other hand, such as ammonium nitrate or guanidine nitrate; compare z. B. German patents 854 770, 851919 and 909 424. Also mixtures of gas-supplying substances and liquid fuels, whereby as gas-supplying substances ! Heterocyclic ring compounds with three or more nitrogen atoms and their derivatives and salts are known from German patent specification 977 699.
Oft ist die bei diesen Reaktionen auftretende Wärmeentwicklung unerwünscht, und so sind Mischungen bekanntgeworden, welche die bei der Oxidation entstehende Wärme durch einen gleichzeitig verlaufenden endothermen Vorgang verbrauchen. Solche Mischungen enthalten z. B. Ammoniumoxalat oder in endothermer Reaktion zerfallende Kohlenwasserstoffe, wie z. B. Cyclopentadien (deutsche Patentschriften 882 825 bzw. 1 150914).Often the heat generated in these reactions is undesirable, and so are mixtures became known, which the heat generated during the oxidation by one at the same time Consume ongoing endothermic process. Such mixtures contain e.g. B. ammonium oxalate or hydrocarbons which decompose in an endothermic reaction, such as. B. Cyclopentadiene (German patents 882 825 or 1 150914).
Derivate des Tetrazols sind zwar auch schon als Bindemittel in Treibladungspulvern bekannt. Der Hauptbestandteil und wichtigste Gaslieferant dieser Treibladungspulver ist jedoch Nitrocellulose, während die Tetrazolderivale lediglich als Plastifizierungsmittel dienen und demzufolge nur in Mengen bis zu 50% eingesetzt werden (USA.-Patentschrift 3073 731).Derivatives of tetrazole are already known as binders in propellant charge powders. Of the The main component and most important gas supplier of this propellant powder, however, is nitrocellulose, while the tetrazole rivals only serve as plasticizers and therefore only in quantities of up to 50% can be used (U.S. Patent 3,073,731).

Die Wasserstoffatome reagieren sauer und bilden daher mit Aminoguanidin die entsprechenden Salze. Deren Herstellung erfolgt z. B. durch Zusammengeben wäßriger Lösungen von Salzen des Aminoguanidins, z. B. Aminoguanidinsulfat, mit wäßrigen Lösungen von Alkalisalzen der genannten Tetrazole, wobei die unlöslichen Verbindungen ausfallen, die gemäß der vorliegenden Erfindung zum Einsatz kommen.The hydrogen atoms react acidic and therefore form the corresponding salts with aminoguanidine. Their production takes place z. B. by combining aqueous solutions of salts of aminoguanidine, z. B.
