1,2,4-Trichlorobenzene Chemical Properties,Uses,Production
Description
Trichlorobenzenes (TCBs) are synthetic chemicals that occur in three different isomeric forms. The three chlorinated cyclic aromatic isomers are 1,2,3-trichlorobenzene (1,2,3-TCB), 1,2,4-trichlorobenzene (1,2,4-TCB), and 1,3,5-trichlorobenzene (1,3,5-TCB). 1,2,4-TCB is one of the 188 chemicals designated as a hazardous air pollutant under the Clean Air Act.
Chemical Properties
1,2,4-Trichlorobenzene is a low-melting solid or liquid with a pleasant, aromatic odor. The Odor Threshold is 1.4 ppm.
Physical properties
Colorless liquid with an odor similar to o-dichlorobenzene. Odor threshold concentration is 1.4 (quoted, Amoore and Hautala, 1983). Miscible with most organic solvents and oils; insoluble in water. Combustible.
Definition
ChEBI: 1,2,4-trichlorobenzene is a trichlorobenzene with chloro substituents at positions 1, 2 and 4. It is a solvent in various organic chemical reactions.
Application
Trichlorobenzenes are primarily used as solvents in chemical manufacturing industries. 1,2,4-Trichlorobenzene is economically the most important isomer. It is used as a solvent in chemical reactions to dissolve oils, waxes, and resins. Furthermore, it is also used as a dye carrier. 1,2,4-Trichlorobenzene is a highly chlorinated aromatic solvent. It may be used as a solvent to prepare:
dimethylketene β-lactone dimer from tetramethyl-1,3-cyclobutanedione
salicyl-o-toluide by the reaction of phenyl salicylate and o-toluidine
General Description
Colorless liquid or white solid with a sharp chlorobenzene odor. Melting point 16.95°C (62.5°F) .
Reactivity Profile
1,2,4-Trichlorobenzene can react vigorously with oxidizing materials . Yields hydrogen chloride and phosgene when heated to decomposition [USCG, 1999].
Health Hazard
Exposures to high concentrations via inhalation are potentially hazardous to the lungs, kidneys and liver. Prolonged or repeated exposures or short exposure to high concentrations via inhalation are potentially hazardous to the lungs, kidneys and liver. Prolonged or repeated exposure to the eyes is likely to result in moderate pain and transient irritation. Prolonged or repeated contact with the skin may result in moderate irritation and possible systemic effects. Ingestion: May cause kidney and liver damage.
Safety Profile
Poison by ingestion. Moderately toxic by intraperitoneal route. An experimental teratogen. Experimental reproductive effects. Mutation data reported. A slan irritant. Combustible when exposed to heat or flame. Can react vigorously with oxidizing materials. To fight fire, use water, foam, CO2, dry chemical. When heated to decomposition it emits toxic fumes of Cl-. See also CHLORINATED HYDROCARBONS, AROMATIC.
Potential Exposure
1,2,4-Trichlorobenzene is used as a dye carrier, herbicide intermediate; a heat transfer medium; a dielectric fluid in transformers; a degreaser; a lubricant; as an industrial chemical; solvent, emulsifier, and as a potential insecticide against termites. The other trichlorobenzene isomers are not used in any quantity.
Shipping
UN2321 Trichlorobenzenes, liquid, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.
Purification Methods
Separate it from a mixture of isomers by washing with fuming H2SO4, then water, drying with CaSO4 and slowly fractionally distilling. [Jensen et al. J Am Chem Soc 81 3303 1959, Beilstein 5 IV 664.]
Incompatibilities
Reacts violently with oxidants, acids, acid fumes; steam.
Waste Disposal
Incineration, preferably after mixing with another combustible fuel. Care must be exercised to assure complete combustion to prevent the formation of phosgene. An acid scrubber is necessary to remove the halo acids produced.
