Trinitrotoluene or TNT, or more specifically 2,4,6-trinitrotoluene, is a chemical compound with the formula C₆H₂(NO₂)₃CH₃. TNT's most common use is that of an explosive material, with both military and (some) civilian applications. The explosive yield of TNT is considered to be the standard measure of strength of explosive materials.

Properties

Chemical

TNT explodes when set off.

Physical

TNT is a yellowish solid, insoluble in water but readily soluble in organic solvents.

Explosive

TNT is a relative insensitive explosive, with a RE factor of 1.00 and a detonation velocity of 6900 m/s.

Availability

Chemical suppliers do not sell bulk TNT, but rather diluted solutions, mainly for analysis. These however are not available to the amateur chemist.

Preparation

TNT can be prepared by nitrating toluene to mononitrotoluene, then dinitrotoluene and finally trinitrotoluene using a nitrating mixture.

Projects

• Make blasting charge

Handling

Safety

TNT is extremely toxic. Exposure to TNT leads to the skin turning yellow, and people with such condition during WWI (women working in munitions factories) were nicknamed "canaries" or "canary girls".

Storage

TNT should be stored in closed containers, away from any source of hazard.

Disposal

TNT can be safely neutralized with Fenton's reagent.
