Tri-nitro-toluene(aka T.N.T) – C7H5N3O6
Preparation
In industry, TNT is produced in a three-step process. First, toluene is nitrated with a mixture of sulfuric and nitric acid to produce mono-nitro-toluene (MNT). The MNT is separated and then renitrated to di-nitro-toluene or DNT. In the final step, the DNT is nitrated to trinitrotoluene or TNT using anhydrous mixture of nitric acid and oleum. Nitric acid is consumed by the manufacturing process, but the diluted sulfuric acid can be re-concentrated and reused. Subsequent to nitration, TNT is stabilized by a process called sulphitation, where the crude TNT is treated with aqueous sodium sulfite solution in order to remove less stable isomers of TNT and other undesired reaction products. The rinse water from sulphitation is known as red water and is a significant pollutant and waste product of TNT manufacture

Plastic Explosives
These types of explosives are very dangerous as they can be molded into any shape and are very difficult to detect. They generally have High explosive velocity and a low sensitivity and so are ideal for explosives. They need a blasting cap to be detonated as they have a low sensitivity and have a high explosion temperature. Blasting caps generally consist of lead azide or mercury fulminate.
