클로로브로모메테인 C화학적 특성, 용도, 생산
화학적 성질
white to light yellow crystal powder물리적 성질
Clear, colorless liquid with a sweet, chloroform-like odor용도
Bromochloromethane is used primarily as an extinguishing agent due to its oxygen-depleting properties.정의
ChEBI: A one-carbon compound substituted by a chloro and a bromo group.일반 설명
A clear colorless liquid with a sweet chloroform-like odor. Denser than water (density 1.991 g / cm3) and insoluble in water. Hence sinks in water. Boiling point 68°C. Vapors may cause illness if inhaled. Nonflammable. When exposed to high temperatures may emit toxic fumes. Used as a fire extinguishing agent.공기와 물의 반응
Insoluble in water.반응 프로필
Bromochloromethane is sensitive to light (may discolor). Incompatible with strong bases and strong oxidizing agents. Also incompatible with active metals, calcium, aluminum, magnesium, zinc and their alloys. Attacks some forms of plastics, rubber and coatings. .위험도
By inhalation.건강위험
Toxic by ingestion. Vapors may cause dizziness or suffocation. Exposure in an enclosed area may be very harmful. Contact may irritate or burn skin and eyes. Fire may produce irritating and/or toxic gases. Runoff from fire control or dilution water may cause pollution.화재위험
Some of these materials may burn, but none ignite readily. Most vapors are heavier than air. Air/vapor mixtures may explode when ignited. Container may explode in heat of fire.Safety Profile
Mildly toxic by ingestion and inhalation. Mutation data reported. This material has a narcotic action of moderate intensity, although of prolonged duration. Animals exposed for several weeks to 1000 pprn had blood bromide levels as high as 350 mgl100 g. Therefore, until further data are available, it should be considered at least as toxic as carbon tetrachloride and more than minimal exposure to its vapors should be avoided. Dangerous; when heated to decomposition it emits highly toxic fumes of Brand Cl-. See also BROMIDES and CHLORINATED HYDROCARBONS, ALIPHATIC.잠재적 노출
This compound is used in brominated flame retardants; a fire-extinguishing agent; and in organic synthesisCarcinogenicity
The U.S. EPA classification is D (not classifiable as to human carcinogenicity). Bromochloromethane is structurally similar to dichloromethane (methylene chloride), which is classified B2 (probable human carcinogen). The classification is based on the lack of data regarding the carcinogenicity of bromochloromethane in humans or animals; however, there are data indicative of genotoxic effects and structural relationships to halogenated methanes classified as B2 (probable human carcinogens).환경귀착
Biological. When bromochloromethane (5 and 10 mg/L) was statically incubated in the dark at 25 °C with yeast extract and settled domestic wastewater inoculum for 7 d, 100% biodegradation with rapid adaptation was observed (Tabak et al., 1981).Photolytic. The following rate constants were reported for the reaction of bromochloromethane and OH radicals as measured by both flash photolysis resonance fluorescence and discharge flow electron paramagnetic resonance techniques (x 10-13 cm3/molecule?sec): 0.91 at 4 °C, 1.11–1.13 at 25 °C, 1.32–1.34 at 40 °C, 1.55–1.58 at 57 °C, 1.76–1.90 at 76 °C, 2.10–2.26 at 97 °C (Orkin et al., 1997).
Chemical/Physical. Although no products were identified, the estimated hydrolysis half-life in water at 25 °C and pH 7 is 44 yr (Mabey and Mill, 1978). Bromochloromethane reacts with bisulfide ion (HS-), produced by microbial reduction of sulfate, forming 1,3,5-trithiane and dithiomethane. Estimated reaction rate constants at 25 and 35 °C were 7.29 x 10-5 and 2.42 x 10- 4/M?sec, respectively (Roberts et al., 1992).
