TNT is the abbreviation for 2,4,6-trinitrotoluene [C₇H₅N3O₆ or C₆H₂(CH₃)(NO₂)₃]. TNT is a powerful, highly explosive compound widely used in conventional bombs. Discovered by Joseph Wilbrand (1811–1894) in 1863, it is made by treating toluene with nitric acid and sulfuric acid. This yellow crystalline solid with a low melting point has low shock sensitivity and even burns without exploding. This makes it safe to handle and cast; but once detonated, it explodes violently.
