Sensitiveness high explosives

When mixed with hydrocarbons in approximately stoicheiometric proportions, a sensitive highly explosive mixture is produced which needs careful handling [1,2], The use of such mixtures as rocket propellants has also been investigated [3], Explosion of only 10 g of a mixture with toluene caused 10 deaths and 20 severe injuries [4], The mixture contained excess toluene in error [5], Detonation characteristics of mixtures with benzene, toluene (and nitrobenzene) were studied [6],... 

Booster A cap-sensitive high explosive used to initiate other less sensitive high explosives. 

Secondary high explosive A less sensitive high explosive initiated by another explosive. 

Decaborane (and possibly some other boron hydrides) in the presence of carbon tetrachloride, and possibly other halogenated hydrocarbons, forms a very shock-sensitive high explosive. 

Anhydrous nitric acid is miscible even with hydrocarbons, and the increased availability of high quality white grades increases the danger of inadvertently forming such mixtures. If anywhere near stoichiometric composition, an homogeneous mixture of nitric acid and virtually any organic is a sensitive high explosive. So much was obvious to learned men of the last century, and many such mixtures were patented as... 

PETN [pentaerythritol tetranitrate, C(CH20N02)4] is an extremely sensitive high explosive. When used as a booster explosive, a bursting charge, or a plastic demolition charge, it is desensitized by mixture with trinitrotoluene or by the addition of wax. 

Nitrobenzene and HN03 form dangerous sensitive mixtures (Sprengel Explosives). Nitrobenzene and liq N202 form a powerful and sensitive high explosive. See also under Benzene and... 

A class of relatively sensitive high explosives, the chief representative of which is Tetryl. 

Properties Brownish crystals. Melts with decomposition at 210° and deflagrates at about 226 . Powerful and sensitive high explosive, similar to Tetryl. Detonation rate (d = 1.6) 7500 m/sec. On long storage stability not very satisfactory, particularly in presence of moisture, which tends to promote hydrolysis.37... 

Violent reaction with concentrated sulfuric acid (above 160°C), sulfuric acid + sulfur trioxide (above 52°C). Mixtures with tetranitromethane are sensitive high explosives. May explode on standing. It has been involved in plant scale explosions. When heated to decomposition it emits toxic fumes of NOx. See also other methylnitrobenzene entries and NITRO COMPOUNDS OF AROMATIC HYDROCARBONS. 

A shock- and heat-sensitive high explosive that evolves much flame. Highly dangerous. Upon decomposition it emits highly toxic fumes of NOx. See also NITROSAMINES and EXPLOSIVES, HIGH. 

DADNE is a relatively new, low sensitive high explosive developed by the Swedish Defence Research Agency FOI. It is insoluble in cold water, slightly soluble in acetonitrile and cyclohexanone, soluble in DMSO, dimethylformamide and N-methylpyrrolidinone. Besides, it can cause allergic skin reactions. 

Hazard Strong oxidizing agent ignites violently with combustibles. Shocksensitive may explode when exposed to heat or by spontaneous chemical reaction. Sensitive, high explosive when contaminated with reducing materials. Skin irritant. 

Use Detonating agent for less-sensitive high explosives, indicator (colorless at pH 10.8, dull red at pH 13.0). 

Caution PiDNBT (30) is a sensitive high explosive and should be handled with caution. Impact sensitivity studies show 30 to be more sensitive than dry picric acid and approximately as sensitive as l,3,5-trinitrohexahydro-l,3,5-triazine. 

BLASTING GELATIN or BLASTING OIL (55-63-0) Heat-, UV-, acid, friction-, shock-sensitive high explosive. A flammable liquid (at flash point explodes). Hydrolyzed in water, forming an explosive solution of nitric acid and glycerol. Explodes on contact with ozone or in temperatures above approximately 350°F/176°C. The pure material Is rarely used the commercial material is desensitized.
