- Nitrobenzene is an organic compound with
the chemical formula C6H5NO2.
- It is a water-insoluble pale yellow oil
with an almond-like odor. It freezes to give greenish- yellow
crystals.
- It is produced on a large scale as a
precursor to aniline. Although
occasionally used as a flavoring or perfume additive, nitrobenzene
is highly toxic in large quantities. In the laboratory, it is
occasionally used as a solvent, especially for electrophilic
reagents.
- Nitrobenzene is an oily yellow to
yellow-brown liquid that smells like bitter almonds or shoe polish.
Nitrobenzene dissolves only slightly in water and easily in other
chemicals. It is man- made.
- Very low levels of nitrobenzene may be
found in air and/or water. The levels remain low even near sites
where nitrobenzene is made or used. Nitrobenzene is rarely found in
drinking water.
- Industries manufacture nitrobenzene to
make a chemical called aniline, to make oil for motors and machines,
and to produce dyes, drugs, pesticides and rubber.
- Nitrobenzene is prepared by nitration of
benzene with a mixture of concentrated sulfuric acid, water, and
nitric acid. This mixture is sometimes called "mixed acid."
- The production of nitrobenzene is one of
the more dangerous processes conducted in the chemical industry
because of the exothermicity of the reaction (ΔH = −117 kJ/mol.
- World capacity for nitrobenzene in 1985
was about 1.7×106 tonnes.Approximately 95% of nitrobenzene is
consumed in the production of aniline, which
is a precursor to rubber chemicals, pesticides, dyes, explosives,
and pharmaceuticals.
- Nitrobenzene is also used in shoe and
floor polishes, leather dressings, paint solvents,
and other materials to mask unpleasant odors. Redistilled, as oil of
mirbane, nitrobenzene has been used as an inexpensive perfume for
soaps.
- A significant merchant market for
nitrobenzene is its use in the production of the analgesic
paracetamol.
- Small amounts of nitrobenzene are released
to the air and to bodies of water by the industries that use this
chemical.
- However, it is broken down to other
chemicals within a few days after it is released.
- Air and water in most areas contain no
nitrobenzene or such low amounts that they cannot be measured.
