GENERAL
DESCRIPTION & APPLICATIONS |
Dichlorobenzenes
belong to the group of organic
halogen compounds replacing two hydrogen atoms in benzene
by chlorine atoms. There are three isomers; ortho-dichlorobenzene,
colorless liquid boiling at 180 C, used as a solvent and chemical intermediate
for dyes, pigment, agrochemicals and wide range of organic
synthesis ; meta-
, colorless liquid boiling at
172 C, used as a solvent and chemical intermediate; para- , white solid with a
with a characteristic penetrating odor. It is used mainly as an insecticidal fumigant against
moths, as a space deodorizer, as a general insecticide and fungicide on crops, and as
a chemical intermediate for plastics, dyes, pharmaceuticals
and other organic compounds. All they are insoluble in water
and denser than water. They are prepared by the chlorination
reaction of benzene in the presence of
iron(III) chloride. (the chlorination under strong
illumination and without iron(III) chloride leads to benzene hexachloride
instead of mono or polychlorobenzenes). The chlorination reaction leads to similar
ratio of ortho- and para-dichlorobenzene, but small
amount of the meta
isomer is performed. The ortho and para isomers are
separated by
fractional freezing. While the para isomer
crystallizes, the ortho isomer remains liquid.
The
meta-dichlorobenzene is
prepared by heating and pressure with aluminum chloride.
p-Dichlorobenzene is used mainly as an insecticidal fumigant against
moths, as a space deodorizer, as a general insecticide and fungicide on crops, and as
a chemical intermediate for 2,5-dichloroaniline, plastics
(e.g polyphenylene sulfide resins
used for surface coatings and molding resins), dyes, pharmaceuticals, agrochemicals
and other organic synthesis. |

GENERAL
DESCRIPTION OF CHLOROBENENES |
Chlorobenzenes
are organic halogen compounds of cyclic aromatics formed by replacing hydrogen
atoms in benzene by 1-6 atoms of chlorine. There are 12 compounds of
chlorobenzenes of mono-, three isomeric substances each of di-, tri-, and
tetra-, as well as penta- and hexachlorobenzene.
- Monochlorobenzene ( MCB, CAS RN: 108-90-7)
- 1,2-Dichlorobenzene (1,2-DCB, CAS RN: 95-50-1)
- 1,3-Dichlorobenzene ( 1,3-DCB, CAS RN:
541-73-1)
- 1,4-Dichlorobenzene (1,4-DCB, CAS RN: 106-46-7)
- 1,2,3-Trichlorobenzene (1,2,3-TCB, CAS RN:
87-61-6)
- 1,2,4-Trichlorobenzene (1,2,4-TCB, CAS RN:
120-82-1)
- 1,3,5-Trichlorobenzene (1,3,5-TCB, CAS RN: 108-70-3)
- 1,2,3,4-Tetrachlorobenzene (1,2,3,4-TeCB, CAS RN:
634-66-2)
- 1,2,3,5-Tetrachlorobenzene (1,2,3,5-TeCB, CAS RN:
634-90-2)
- 1,2,4,5-Tetrachlorobenzene (1,2,4,5-TeCB, CAS RN:
95-94-3)
- Pentachlorobenzene (PeCB, CAS RN:
608-93-5)
- Hexachlorobenzene (HCB, CAS RN:
118-74-1)
Chlorobenzenes are white crystalline solids at room
temperature while MCB, 1,2-DCB, 1,3-DCB, and 1,2,4-TCB, are clear liquids. They
are practically insoluble in water and denser than water. . The water solubility
is decreasing if more chlorinated. The flammability of chlorobenzenes are low,
the octanol/water partition coefficients are moderate to high, increasing with
more chlorinated, and vapour pressures are low to moderate, decreasing with more
chlorinated. The taste and odour thresholds are low, decreasing with lower
chlorinated. MCB (which makes up more than 50 % of total production of all
chlorobenzenes) and DCBs (more than 40 %) are prepared by the chlorination
reaction of benzene in the liquid phase in the presence of iron(III) chloride.
(the chlorination under strong illumination and without iron(III) chloride leads
to benzene hexachloride instead of mono or polychlorobenzenes). The chlorination
reaction for DCB leads to similar ratio of ortho- and para-dichlorobenzene, but
small amount of the meta isomer is performed. The ortho and para isomers are
separated by fractional freezing. While the para isomer crystallizes, the ortho
isomer remains liquid. The meta-dichlorobenzene is prepared by heating and
pressure with aluminum chloride. TCBs are obtained from the chlorination of
appropriate chlorobenzene isomers in the presence of a Lewis acid catalyst.
TeCBs are achieved by the addition of chlorine to trichlorobenzenes in the
presence of an aluminium catalyst. PCB is produced by the denitrification of
pentachloronitrobenzene and the reductive dechlorination of HCB as well as by
the addition of chlorine to TeCB. HCB is produced by the direct chlorination of
benzene with ferric chloride catalyst at 150-200 C from the distillation of
residues from the production of tetrachloroethylene. Chlorobenzenes are used
mainly as process solvents and solvent carriers as well as parent compounds in
the synthesis of pesticides (mainly), plastics, dyes, pharmaceuticals and other
organic compounds. They are used as insecticidal fumigants against moths,
as space deodorizers, as general insecticides and fungicides on crops. They are
used in metal treatments; in industrial deodorants; in cleaners for drains.
Higher chlorinated benzenes of TCBs, TeCBs are used in dielectric fluids.
