TNT revolutionized civil engineering and has cemented itself in the public consciousness as the definition of explosives. TNT is actually an acronym, representing Trinitrotoluene. Its chemical formula is C 6 H 2 (NO 2) 3 CH 3. Contrary to popular belief, TNT is a completely different beast from dynamite. TNT was invented in 1863, just four years before dynamite, by German chemist Joseph Wilbrand.
