Toluene (C6H5CH3), also known as methylbenzene, is a colorless hydrocarbon liquid, an aromatic compound produced from coal tar and by catalytic reforming of petroleum hydrocarbons. Toluene is used as a solvent, in gasoline, and for making TNT, benzaldehyde, benzoic acid, etc. Molecular weight 92.2, melting point -95°C, boiling point 111°C.


TNT (trinitrotoluene) is a pale yellow crystalline solid by nitration of toluene. It is the most extensively used high explosive, being relatively insensitive to shock, especially when melted by steam heating and cast. Molecular weight TNT 227.1, melting point 82°C.
