Detonators compound

Fuel and oil compounds detonate on contact with nitric acid, if they contain 15 to 20% of unsaturated compounds. 

Chloro-2-nitrobenzene was distilled under reduced pr sure by steam heating. The compound detonated at the end of the distillation. 

An N-nitrose compound that is unstable is obtained by the effect of dinitrogen trioxide on caproiactam at a low temperature. The compound detonates when the medium is not cooled enough. 

An attempt to dry trimethyl phosphite by using magnesium perchlorate ended with the compounds detonation. This accident was put down to the formation of methyl perchlorate. However, by analogy with a similar accident described in... 

The Detonator Mk37 Mod O is a compound detonator" contg two increments of LA and one of Tetryl. It is used in auxiliary detonating Fuzes Mk44 46 and is initiated by the detonation of a LA detonator in the nose fuze. Detonator Mk37 initiates a Tetryl lead (Ref 23, pp 4-1 to 4-5)... 

Accdg to Gorst (Ref 71, pp 15—16, it was proposed in Russia to use LA (Lead Azide) in lieu of MF (Mercuric Fulminate) in compound detonators with Tetryl and later with Ten (PETN). Much work on improvement of LA detonators was done by Col A.A. Solonina. 

Hexanitroazobenzene is a very powerful and brisant high expl. Its Power as measured by the Trauzl test is 113% PA or 123% TNT and its Impact Sensitivity is between that of tetryl and PA the FI value is 617t> PA. According to Davis (Kef 3) this expl is suitable for boosters and compound detonators. Tke presence of the a o group in hexanitro azobenzene makes it more powerful and brisant than hexanitrodipbenylamine (qv)... 

Medard also examined several binary and ternary mixts contg Bitetryl, such as a)50-50-Bi-tetryl/TNT- a cast HE, d 1.48-1.50, vel of deton 7100 to 7400m/s b)50/30/20-Bitetryl/Ethyltetryl-/Tetryl, a castable, plastic HE, d 1.58 it could not be initiated by as much as 2g of MF, but required a compound detonator for complete initiation... 

Aromatic nitro compounds are generally stable but are frequently reactive, especially if they contain groups other than nitro groups in the meta position with respect to one another. As a class they constitute the most important of the military high explosives. They are also used as components of smokeless powder, in compound detonators, and in primer compositions. Liquid nitro compounds, and the mixtures which are produced as by-products from the manufacture of pure nitro compounds for military purposes, are used in non-freezing dynamite and other commercial explosives. The polynitro compounds are solvents for nitrocellulose. 

Nitromannite is about as sensitive as nitroglycerin to shock and to friction. It detonates under a 4-cm. drop of a 2-kilogram weight, and may be exploded readily on a concrete surface by a blow of a carpenter s hammer. It is not fired by the spit of a fuse, but is made to detonate by the flame of a match which causes local overheating. It is almost, but not quite, a primary explosive. It is used as the high-explosive charge in compound detonators which contain the relatively safe diazodinitrophenol as the primary explosive. A mixture of nitromannite and tetra-cene is a powerful and brisant primary explosive which detonates from moderate heat. 

PETN is extraordinarily sensitive to initiation. It is detonate by 0.01 gram of lead azide, whereas tetryl requires 0.025 gram of lead azide for its certain detonation. This sensitivity and its. great brisance combine to make PETN exceptionally serviceable in compound detonators.

Detonators which thus make use of the principle of the booster are known as compound detonators and are made both with and without reenforcing caps. Some manufacturers insert the reenforcing cap with the perforated end down, others with the perforated end up.20... 

Lead azide is not used in primers where it is desired to produce fire or flame from impact. Fulminate mixtures and certain mixtures which contain no fulminate are preferred for this purpose. Lead azide is used where it is desired to produce, either from flame or from impact, an initiatory shock for the detonation of a high explosive—in compound detonators as already described, and in the detonators of artillery fuzes. For the latter purpose, caps containing azide and tctryl (or other booster explosive) are... 

In the Trauzl test, trinitrotriazidobenzene gives 90% as much net expansion as PETN tctryl gives 70%, TNT 60%, mercury fulminate 23%, and lead azide 16%. Used as a high explosive in compound detonators and initiated with lead azide, trinitrotriazidobenzene is about as strong as PETN and is stronger than tetryl. 

A diazomethane precursor, this compound detonates on high impact sample explodes when heated in a sealed capillary tube.3... 

Fidlar patented a flashlegs propellent explosive formed of nitrocellulose, starch, and dinitrotoluene. Grotta patented compound detonators with a priming charge formed of mercury fulminate, a heavy-metal azide, and a secondary charge formed of a mixture of equal amounts of Tetryl and potassium chlorate. 

Uses Similar to Trinitrophenylmethylnitramine (See). Particularly effective as a base charge in compound detonators.

An unstable compound. Detonation can be initiated by heat, friction, or impact. See also CHROMIUM COMPOUNDS. Explodes 50°. When heated to decomposition it emits toxic fumes of NOx. 

The triazole (346) can be used to stabilize plastics (73JAP7308667). The reaction of tributyl lead hydroxide and aminotriazole affords (347) which has been recommended as an antiwear component of lubricating oils (68FRP1525268). Diazonium compounds detonate, although they are safer to handle than comparable derivatives of tetrazole. Polyfluorotriazolines (67USP3326889) are oxidants their suitability as bleaching agents, for rocket fuels and constituents of pyrotechnic compositions has been claimed.
