Chemical Properties:：

Toluene (molecular formula: C7H8) is a homologue of benzene, also known as “methyl benzene” and “phenyl methane”. It is a colorless, volatile liquid with a special aroma. Toluene is a member of aromatic hydrocarbons. In the air, toluene can only incompletely burn and the flame is yellow. Many of its properties are similar to those of benzene and have aromatic odors similar to those of benzene. In practice, they are often used as organic solvents instead of the rather toxic benzene.
Toluene is prone to chlorination and produces benzene-chloromethane or benzene-trichloromethane, both of which are good industrial solvents; it can extract bromine from the bromine water, but cannot react with bromine water; it is also easy to nitrify and produce nitrotoluene or o-nitrotoluene, both of which are the raw materials of dyes; one part of toluene and three parts of nitric acid are nitrated to give trinitrotoluene (common name TNT); it is also easily sulfonated to generate o-toluenesulfonic acid or p-toluenesulfonate which are the raw materials for making dyes or making saccharin. Toluene vapor mixes with air to form explosive substances, so it can make TNT explosives.

Application：

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.

Toluene has numerous applications in the chemical and petroleum industry, with approximately 6 million tons used annually in the United States and 16 million tons used globally. The major use of toluene is as an octane booster in gasoline. Toluene has an octane rating of 114. Toluene is one of the four principal aromatic compounds, along with benzene, xylene, and ethylbenzene, that are produced during refining to enhance gasoline’s performance. Collectively, these four compounds are abbreviated as BTEX. BTEX is a major component of gasoline, forming about 18% by weight of a typical blend. Although the proportion of the aromatics is varied to produce different blends to meet geographic and seasonal requirements, toluene is one of the major components. A typical gasoline contains approximately 5% toluene by weight.
Toluene is a primary feedstock used to produce various organic compounds. It is usedto produce diisocyanates. Isocyanates contain the functional group ?N = C = O, and diisocyanatescontain two of these. The two main diisocyanates are toluene 2,4-diisocyanate andtoluene 2,6-diisocyanate. The production of diisocyanates in North America is close to a billionpounds annually. More than 90% of toluene diisocyanate production is used for makingpolyurethanes foams. The latter are used as flexible fill in furniture, bedding, and cushions.In rigid form it is used for insulation, hard shell coatings, building materials, auto parts, androller skate wheels.

In manufacture of benzoic acid, benzaldehyde, explosives, dyes, and many other organic Compounds; as a solvent for paints, lacquers, gums, resins; thinner for inks, perfumes, dyes; in the extraction of various principles from plants; as gasoline additive.
