Description and Uses

Toluene is a clear, colourless liquid with a sweet, benzene-like odour. Toluene occurs naturally in crude oil and in the toluene tree. It is also produced in the process of making gasoline and other fuels from crude oil and making coke from coal. Toluene is used in making paints, paint thinners, fingernail polish, lacquers, adhesives, and rubber and in some printing and leather tanning processes. Toluene is also used in the production of polymers used to make nylon, plastic soda bottles, and polyurethanes and for pharmaceuticals, dyes, cosmetic nail products, and the synthesis of organic chemicals.
Toluene has been reported as the most commonly abused hydrocarbon solvent, primarily through ‘glue sniffing’. The common possibilities of exposure to high levels of toluene include indoor air from the use of household products such as paints, paint thinners, adhesives, synthetic fragrances, and many other sources.

Toluene is derived from coal tar as well aspetroleum. It occurs in gasoline and manypetroleum solvents. Toluene is used to producetrinitrotoluene (TNT), toluene diisocyanate,and benzene; as an ingredient fordyes, drugs, and detergents; and as an industrialsolvent for rubbers, paints, coatings, andoils.
