Im folgenden wird die Erfindung durch Beispiele näher beschrieben, ohne dass sie dadurch eingeschränkt werden soll:In the following, the invention will be described in more detail by way of example, without it being intended to limit it:

Herstellung der ZündstoffeProduction of the explosives

2-Diazo-4,6-dinitrophenol (Diazodinitrophenol oder Diazol) wird durch Diazotierung von Natriumpikramat hergestellt. 2-Diazo-4,6-dinitrophenol (diazodinitrophenol or diazole) is prepared by diazotization of sodium picrate.

Kaliumdinitrobenzofuroxanat (Kaliumbenzanat) wird durch Neutralisation von Dinitrobenzofuroxan mit Kaliumhydrogencarbonat im wässrigen Medium hergestellt. Kaliumdinitrobenzofuroxanat (potassium benzanate) is prepared by neutralization of dinitrobenzofuroxan with potassium bicarbonate in an aqueous medium.

Ausführungsbeispieleembodiments Beispiel 1example 1

Während kleine Massen von Diazodinitrophenol (Diazol) oder Dipikrylditetrazol, z. B. 5 mg, bei Verwendung eines Metallschichtelementes nicht durchzünden, wird durch einen Zusatz von 30 % Kaliumdinitrobenzofuroxanat eine Sensibilisierung erreicht, wodurch eine sichere Durchzündung gewährleistet wird.While small masses of diazodinitrophenol (diazole) or dipicrylditetrazole, e.g. B. 5 mg, do not burn through when using a metal layer element, sensitization is achieved by the addition of 30% Kaliumdinitrobenzofuroxanat, whereby a secure ignition is ensured.

Größere Diazodinitrophenolmassen zünden zwar infolge Eigenverdämmung durch, doch besteht dann die Gefahr einer Detonation.Although larger Diazodinitrophenolmassen ignite due to self-attenuation, but then there is a danger of detonation.

Eine sichere Durchzündung auch von kleinen Diazodinitrophenolmassen wird durch eine Verdämmungsschicht aus Inertstoff oder durch eine thermische Aufladung bewirkt.A secure ignition even of small Diazodinitrophenolmassen is effected by a Eindämmungsschicht inert or by a thermal charge.

Beispiel 2Example 2

Schichten aus Kaliumdinitrobenzofuroxanat, mit einem Druck von bis zu 10 000 bar verdichtet, zünden bei Verwendung eines Metallschichtelementes ohne Verdämmung sicher durch.Layers of potassium dinitrobenzofuroxanate, compacted with a pressure of up to 10 000 bar, ignite safely when using a metal layer element without damming.

Beispiel 3Example 3

Ein Anzündsatz aus 50 % Kaliumdinitrobenzofuroxanat, 45 % Zinkperoxid und 5 % Titan oder Bor zündet bei Verwendung eines Metallschichtelementes ohne Verdämmungsschicht sicher durch.An ignition charge of 50% Kaliumdinitrobenzofuroxanat, 45% zinc peroxide and 5% titanium or boron ignites safely when using a metal layer element without Dämämmungsschicht.
