1,2-디클로로벤젠 화학적 특성, 용도, 생산

물성
어느 이성질체나 에탄올·에테르에는 녹으나 물에는 녹지 않는다. 벤젠을 철촉매의 존재 하에 염소화하면 모노클로로벤젠을 거쳐 p- 및 o-디클로로벤젠이 약 2:1의 비율로 생성한다.
화학적 성질
1,2-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%.
물리적 성질
Clear, 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 ppb_v) was reported by Punter (1983).
용도
1,2-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.
생산 방법
1,2-Dichlorobenzene is produced by reacting liquid benzene with gaseous chlorine in the presence of a catalyst at moderate temperature and atmospheric pressure.
Dichlorobenzenes 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.
정의
ChEBI: 1,2-dichlorobenzene is a dichlorobenzene carrying chloro substituents at positions 1 and 2. It has a role as a hepatotoxic agent and a metabolite.
일반 설명
A 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.
공기와 물의 반응
Insoluble in water.
반응 프로필
1,2-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. .
건강위험
1,2-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.
화재위험
Special Hazards of Combustion Products: Poisonous vapors including hydrogen chloride gas, chlorocarbons, chlorine
화학 반응
Reactivity 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 Profile
Poison 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.
잠재적 노출
The 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
Purification Methods
Contaminants may include the p-isomer and trichlorobenzene [Suslick et al. J Am Chem Soc 106 4522 1984]. It should be shaken with conc or fuming H2SO4, washed with water, dried with CaCl2, and distilled from CaH2 or sodium in a glass-packed column. Low conductivity material (ca 10-10 mhos) has been obtained by refluxing with P2O5, fractionally distilling and passing it through a column packed with silica gel or activated alumina: it is stored in a dry-box under N2 or with activated alumina. [Beilstein 5 IV 654.]
비 호환성
1,2-Dichlorobenzene forms hydrogen chloride gas when in the presence of strong oxidizers or chemically active metals like aluminum, or when heated to decomposition (HSDB 2007).
폐기물 처리
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. Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform with EPA regulations governing storage, transportation, treatment, and waste disposal
