m-디클로로벨젠 MSDS


1,3-Dichlorobenzene

m-디클로로벨젠 C화학적 특성, 용도, 생산

화학적 성질

colourless liquid

화학적 성질

There are three isomeric forms of dichlorobenzene (DCB): m-DCB is a flammable liquid and vapor.

물리적 성질

Clear, colorless liquid with a disinfectant or musty-type odor. At 40 °C, the average odor threshold concentration and the lowest concentration at which an odor was detected were 170 and 177 μg/L, respectively. At 25 °C, the lowest concentration at which a taste was detected was 190 μg/L, respectively (Young et al., 1996).

용도

Fumigant and insecticide; organic synthesis.

정의

ChEBI: A dichlorobenzene carrying chloro substituents at positions 1 and 3.

Synthesis Reference(s)

The Journal of Organic Chemistry, 48, p. 250, 1983 DOI: 10.1021/jo00150a020

일반 설명

Colorless liquid. Sinks in water.

공기와 물의 반응

1,3-Dichlorobenzene is sensitive to moisture. Insoluble in water.

반응 프로필

1,3-Dichlorobenzene is incompatible with oxidizing agents and aluminum and its alloys. Above the flash point, explosive vapor-air mixtures may be formed.

건강위험

INHALATION: Causes headache, drousiness, unsteadiness. Irritating to mucous membranes. EYES: Severe irritation. SKIN: Severe irritation. INGESTION: Irritation of gastric mucosa, nausea, vomiting, diarrhea, abdominal cramps and cyanosis.

화재위험

Special Hazards of Combustion Products: Irritating vapors including hydrogen chloride are produced.

Safety Profile

Moderately toxic by intraperitoneal route. Mutation data reported. When heated to decomposition it emits toxic fumes of Cl-. See also oDICHLOROBENZENE and p DICHLOROBENZENE.

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

환경귀착

Biological. When 1,3-dichlorobenzene was statically incubated in the dark at 25 °C with yeast extract and settled domestic wastewater inoculum, significant biodegradation with gradual acclimation was followed by a deadaptive process in subsequent subcultures. At a concentration of 5 mg/L, 59, 69, 39, and 35% losses were observed after 7, 14, 21, and 28-d incubation periods, respectively. At a concentration of 10 mg/L, percent losses were virtually unchanged. After 7, 14, 21, and 28-d incubation periods, percent losses were 58, 67, 31, and 33, respectively (Tabak et al., 1981).
Photolytic. The sunlight irradiation of 1,3-dichlorobenzene (20 g) in a 100-mL borosilicate glass-stoppered Erlenmeyer flask for 56 d yielded 520 ppm trichlorobiphenyl (Uyeta et al., 1976).
Chemical/Physical. Anticipated products from the reaction of 1,3-dichlorobenzene with atmospheric ozone or OH radicals are chlorinated phenols, ring cleavage products, and nitro compounds (Cupitt, 1980). Based on an assumed base-mediated 1% disappearance after 16 d at 85 oC and pH 9.70 (pH 11.26 at 25 oC), the hydrolysis half-life was estimated to be >900 yr (Ellington et al., 1988). 1,3-Dichlorobenzene (0.17–0.23 mM) reacted with OH radicals in water (pH 8.7) at a rate of 5.0 x 109/M·sec (Haag and Yao, 1992).

운송 방법

m-DCB: UN2810 Toxic liquids, organic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required. United States DOT Regulated Marine Pollutant. UN3077 Environmentally hazardous substances, solis, n.o.s., Hazard class: 9; Labels: 9-Miscellaneous hazardous material, Technical NameRequired. UN3082 Environmentally hazardous substances, liquid, n.o.s., Hazard class: 9; Labels: 9-Miscellaneous hazardous material, Technical Name Required

Purification Methods

Wash it with aqueous 10% NaOH, then with water until neutral, dry and distil it. Conductivity material (ca 10-10 mhos) has been prepared by refluxing over P2O5 for 8hours, then fractionally distilling, and storing with activated alumina. m-Dichlorobenzene dissolves rubber stoppers. [Beilstein 5 IV 657.]

비 호환성

For o-DCB and m-DCB: acid fumes, chlorides, strong oxidizers; hot aluminum, or aluminum alloys. For p-DCB: Strong oxidizers; although, incompatibilities for this chemical may also include other materials listed for o-DCB.

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
