>> Toluene
Toluene,
also known as methylbenzene, or Toluol, is a clear
water-insoluble liquid with the typical smell of
paint thinners, reminiscent of the related compound
benzene. It is an
aromatic hydrocarbon that is widely used as an industrial
feedstock and as a
solvent. Like other solvents, toluene is also used as an
inhalant drug for its intoxicating properties; however this
causes severe neurological harm.

Toluene reacts as a normal aromatic hydrocarbon towards
electrophilic aromatic substitution.The methyl group makes it around
25 times more reactive than benzene in such reactions.
It undergoes smooth sulfonation to give p-toluenesulfonic acid, and
chlorination by Cl2 in the presence of FeCl3 to give ortho and para
isomers of chlorotoluene.
It undergoes nitration to give ortho and para nitrotoluene isomers,
but if heated it can give dinitrotoluene and ultimately the
explosive trinitrotoluene
With other reagents the methyl side chain in toluene may react,
undergoing oxidation. Reaction with potassium permanganate leads to
benzoic acid, whereas reaction with chromyl chloride leads to
benzaldehyde (Étard reaction).
Halogenation can be performed under free radical conditions. For
example, N-bromosuccinimide (NBS) heated with toluene in the
presence of AIBN leads to benzyl bromide.
Catalytic hydrogenation of toluene to methylcyclohexane requires a
high pressure of hydrogen to go to completion, because of the
stability of the aromatic system. pKa is approximately 45.
Usage:
Toluene is an Aromatic chemical produced by Petroleum Refineries/
Petrochemical Plants. Steel plants produce Toluene from the
by-product recovery plant where aromatics are recovered from the
coke oven gas.
Toluene is used mainly in production of various downstream
petrochemicals, pesticides, explosives (Tri-Nitro Toluene),
Adhesives, Saccharins, etc. Besides Toluene finds a major end-use in
paint industry as thinner. Toluene is also used as solvents in
various chemical industries.
Toluene is a parent substance in the manufacture of benzene
derivatives, caprolactam, saccharine, pharmaceuticals, dyes,
perfumes, TNT and detergents. It is used in fuels (anti-knock
additive) and as a solvent for paints and coatings, rubber, resins,
thinners in nitrocellulose lacquers and adhesives.
It serves as a raw material in the manufacture of phenol
(predominantly in Western Europe), benzene, cresol (chiefly Japan)
and a wide range of other substances.
Toluene chemical is also known as phenyl-methane or methyl-benzene.
This chemical is transparent like pure water but not soluble in
water. This has a smell like paint thinners and redolent of the
sweet fragrance alike benzene compound.
Toluene chemicals belong to aromatic hydrocarbon group and are
widely used as solvents and industrial feedstock. Further, these can
be used as inhalant drugs for their intoxicating properties.

Handling and Storage
Protect against physical damage. Store in a cool, dry
well-ventilated location, away from any area where the fire hazard
may be acute. Outside or detached storage is preferred. Separate
from incompatibles.
Containers should be bonded and grounded for transfers to avoid
static sparks. Storage and use areas should be No Smoking areas. Use
non-sparking type tools and equipment, including explosion proof
ventilation.
Containers of this material may be hazardous when empty since they
retain product residues (vapors, liquid); observe all warnings and
precautions listed for the product.
