Toluene formerly known as Toluol is a clear, water insoluble liquid with the typical smell of paint thinners. It is a mono substituted benzene derivative whose systematic name is Methyl Benzene and is an aromatic hydrocarbon. Toluene is widely used as an industrial feedstock and as an important organic solvent. Mainly used as a precursor to benzene, Toluene is a common solvent that has ability to dissolve in paints, paint thinners, silicone sealants, many chemical reactants, rubber, printing ink, adhesives, lacquers, leather tanners, and disinfectants. It is also a raw material for Toluene di isocynate and TNT. In addition, it is used as a solvent for carbon nanotubes. Toluene can be used to break open red blood cells in order to extract hemoglobin in biochemistry experiments. Toluene has also been used as a coolant for its good heat transfer capabilities in sodium cold traps used in nuclear reactor system loops. Toluene had also been used in the process of removing the cocaine from coca leaves in the production of Coca-Cola syrup.
