Definitions

• the present invention relates to the use of carbonyl compounds, namely 5,6-carbonyl-ascorbic acid or 5,6-carbonyl-erythorbic acid for the production of explosives (explosives, shooting or fuels and pyrotechnic substances), and a method for producing such explosives , and these explosives themselves.
• explosives based on ascorbic acid or erythorbic acid are known, which are produced by heating ascorbic acid or erythorbic acid together with a nitrate-containing oxidizing agent or by heating one degradation product obtained from ascorbic acid or erythorbic acid mixed with a nitrate-containing oxidizing agent.
• the present invention thus relates to a method for producing explosives, which consists in that 5,6-carbonyl-ascorbic acid or 5,6-carbonyl erythorbic acid mixed with a nitrate-containing oxidizing agent and optionally with other additives.
• the 5,6-carbonyl-ascorbic acid and its production is from the Japanese patent publication 7031601 (13.10.1970), abstracted in C.A. 74 (1971) Ref. 88 266 C known.
• the corresponding erythorbic acid derivative can be prepared analogously.
• the nitrate-containing oxidizing agent used is preferably an alkali metal or alkaline earth metal nitrate, in particular potassium nitrate, or ammonium nitrate or a mixture of these nitrates.
• the nitrate-containing oxidizing agent and the carbonyl compound are preferably used in a weight ratio of about 40:60 - 80:20, preferably about 60:40 - 65:35.
• the explosives according to the invention are characterized in that they are a mixture of 5,6-carbonyl-ascorbic acid or 5,6-carbonyl-erythorbic acid and a nitrate-containing oxidizing agent, and if appropriate contain further additives.
• the nitrate-containing oxidizing agent is preferably an alkali or alkaline earth metal nitrate, in particular potassium nitrate, or ammonium nitrate or a mixture of these nitrates.
• Organic nitrates can be used as further nitrate-containing oxidizing agents.
• An organic nitrate is to be understood here to mean any customary, carbon-containing nitrate with a stoichiometric excess of oxygen, which is usually used in the pyrotechnic industry or in the explosives industry.
• suitable organic Nitrates are nitrocellulose, nitroglycerin or pentaerythritol tetranitrate.
• the weight ratio between the nitrate-containing oxidizing agent (based on potassium nitrate) and the carbonyl compound is about 40: 60 - 80: 20, in particular about 60: 40 - 65: 35.
• the mixture according to the invention can contain additives such as gelling agents or stabilizers, such as substituted ureas, e.g. Arkardit® or Centralit®; substituted urethanes, phthalates, polymers, additives to light sets such as sodium, barium, strontium or copper salts, as well as other additives, e.g. to increase the explosion energy or to improve other desirable properties such as boron or nitroguanidine.

• the explosive according to the invention can be used as an explosive, e.g. used in mining, as a gun or fuel or as a pyrotechnic material or as a high-energy mixture for various drive purposes.
• This explosive can be used, for example, for the manufacture of cartridges or cartridges, for light or signal ammunition, for rockets, for shooting devices for technical purposes, and for fireworks or the like.
• the explosive according to the invention is characterized by low corrosiveness, high driving force and low smoke development. Compared to similar known explosives, it has the following advantageous properties: higher explosive power, significantly lower hygroscopicity, better stability.
