What is explosive


Explosives, technically applicable, chemically uniform substances or mixtures of substances that are able to convert within a very short time with the release of heat and considerable amounts of gas (explosion). The implementation of most E. is an oxidation of carbon with oxygen. In the case of explosive mixtures of components that are not in themselves explosive, the oxygen carriers used are usually alkali nitrates and alkali chlorates and perchlorates.

Classification. The E. are according to their chem. and physical properties or divided according to their mode of action into explosives, initial explosives, low-smoke powders and pyrotechnic charges.

1) Explosives are E. that require a special initial impulse to initiate the detonation. They are divided into uniform compounds and mixtures of explosives.

a) At the uniform connections one differentiates according to their chem. Structure as follows: Nitric acid ester: Glycerol trinitrate (nitroglycerin, explosive oil), ethylene glycol dinitrate (nitroglycol, explosive oil), pentaerythritol tetranitrate (nitro penta), cellulose nitrate (nitrocellulose) and the like;

Nitro compounds: 2,4,6-trinitrophenol (picric acid), 2,4,6-trinitrotoluene (Trotyl); Nitroguanidine, 2,4,6-trinitroresorcinol (styphnic acid) and others;

Nitramines:1,3,5-trinitro-1,3,5-triazacyclohexane (hexogen), 1,3,5,7-tetranitro-1,3,5,7-tetraazaoctane, 2,4,6-trinitrophenyl-methyl-nitramide (Tetryl) among others;
