GENERAL
DESCRIPTION
AND APPLICATIONS
Toluene (methylbenzene) has a methyl group attached to a benzene ring.
alpha-Chlorinated toluenes are organic compounds which one of the hydrogen atoms
in the methyl group has been substituted by a chlorine atom instead of the
substitution in the benzene ring . All three hydrogens in the methyl group can
be replaced by chlorine atoms thtough the free radical chain reaction. These
reactions are catalysed by light and sometimes called photochemical reaction.
They reacts vigorously with strong oxidants and water to produce hydrogen
chloride and attacks many metals except nickel and lead in the presence of
water. Chloromethylated aromatic compounds are used as monomer for a copolymerization and as intermediate in organic synthesis for the introduction
of the benzyl protecting group for alcohols and carboxylic acids such as
benzaldehyde and cinnamic acid. Benzyl chloride, (monochloromethyl)benzene, is a
clear to yellowish liquid; melts at -39 C; boils at 179 C. Its oxidation
reaction produces benzaldehyde.Benzyl Chloride is widely used as an
intermediate for manufacturing organic compounds including benzyl alcohol,
benzyl cyanide and other benzyl compounds. It is used in fuel as a gum inhibitor. Benzal chloride,
(dichloromethyl)benzene, is a clear to yellowish liquid; melts at -17 C; boils
at 206 C. Its oxidation reaction with an alkali produces benzaldehyde. alpha-Chlorinated toluenes
are used in the end applications of
perfumery, dyes, pharmaceuticals, synthetic resins, photographic chemicals,
warfare chemicals, penicillins, quaternary ammonium compounds, plasticizer and
esters.
