1,2-Dichlorobenzene Usage And Synthesis
Chemical Propertiescolourless liquid
Chemical PropertiesThere are three isomeric forms of dichlorobenzene (DCB): m-DCB is a flammable liquid and vapor.
Chemical Properties1,2-Dichlorobenzene (DCB, o-Dichlorobenzene, ODB, Orthodichlorobenzene), C6H4Cl2, is a colorless to pale yellow liquid with a pleasant aromatic odor. It is a combustible liquid and can form explosive mixtures with air at or above 151°F. Combustion and thermal decomposition products include hydrogen chloride gas, phosgene and chloro-carbons. Its flammable (explosive) limits are as follows: Lower 2.2%, Upper 9.2%.
Physical propertiesClear, colorless to pale yellow liquid with a pleasant, aromatic, grassy or vegetable-type odor. At 40 °C, the lowest concentration at which an odor was detected was 200 μg/L. At 25 °C, the lowest concentration at which a taste was detected was 200 μg/L (Young et al., 1996). A detection odor threshold concentration of 4.2 mg/m3 (699 ppbv) was reported by Punter (1983).
Uses1,2-Dichlorobenzene is used as a solvent; asa fumigant; as an insecticide for termites;as a degreasing agent for metals, wool, andleather; and as a heat transfer medium.
UsesSolvent for waxes, gums, resins, tars, rubbers, oils, asphalts; insecticide for termites and locust borers; fumigant; deodorizer; removing sulfur from illuminating gas; as degreasing agent for metals, leather, wool; as ingredient of metal polishes; as heat transfer medium; as intermediate in the manufacture of dyes.
DefinitionChEBI: A dichlorobenzene carrying chloro substituents at positions 1 and 2.
Production MethodsDichlorobenzenes are primarily produced by the chlorination of benzene in the presence of a catalyst (FeCl3 or AlCl3) although there are other possible synthetic routes. The two commercially important isomers are the ortho- and para-dichlorobenzenes.
General DescriptionA clear colorless liquid with a pleasant odor. Denser than water and insoluble in water. Flash point 150°F. Toxic by inhalation and ingestion. Used to make other chemicals, solvents, fumigants and insecticides and for many other uses.
Air & Water ReactionsInsoluble in water.
Reactivity Profile1,2-Dichlorobenzene is sensitive to prolonged exposure to light. 1,2-Dichlorobenzene can react vigorously with oxidizers. 1,2-Dichlorobenzene is incompatible with aluminum and aluminum alloys. 1,2-Dichlorobenzene attacks some forms of plastics, rubber and coatings. .
Health HazardChronic inhalation of mist or vapors may result in damage to lungs, liver, and kidneys. Acute vapor exposure can cause symptoms ranging from coughing to central nervous system depression and transient anesthesia. Irritating to skin, eyes, and mucous membranes. May cause dermatitis.
Health Hazard1,2-Dichlorobenzene exhibits low acute toxi city by inhalation, ingestion, and skin absorp tion. It is more toxic than chlorobenzene.The symptoms are lacrimation, depression ofcentral nervous system, anesthesia, and liverdamage. Lethal concentration in rats for a7-hour exposure period is in the range of800 ppm. The oral LD50 value in rabbits is500 mg/kg. There is no evidence of carcino genicity in animals.
Fire HazardSpecial Hazards of Combustion Products: Poisonous vapors including hydrogen chloride gas, chlorocarbons, chlorine
Chemical ReactivityReactivity with Water No reaction; Reactivity with Common Materials: No reaction; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.
Safety ProfilePoison by ingestion and intravenous routes. Moderately toxic by inhalation and intraperitoneal routes. An experimental teratogen. Other experimental reproductive effects. An eye, skin, and mucous membrane irritant. Causes liver and hdney injury. Questionable carcinogen. Mutation data reported. A pesticide. Flammable when exposed to heat or flame. Can react vigorously with oxidizing materials. To fight fire, use water, foam, CO2, or dry chemical. Slow reaction with aluminum may lead to explosion during storage in a sealed aluminum container. When heated to decomposition it emits toxic fumes of Cl-. See also CHLOROBENZENE and CHLORINATED HYDROCARBONS, AROMATIC.
Potential ExposureThe major uses of o-DCB are as a process solvent in the manufacturing of toluene diisocyanate and as an intermediate in the synthesis of dyestuffs, herbicides, and degreasers. p-Dichlorbenzene is used primarily as a moth repellant, a mildew control agent; space deodorant; and in insecticides, which accounts for 90% of the total production of this isomer. Information is not available concerning the production and use of m-DCB. However, it may occur as a contaminant of o-or p-DCB formulations. Both o-and p-isomers are produced almost entirely as by-products during the production of monochlorobenzene
