MSDS Information

• Bromochloromethane

ブロモクロロメタン 化学特性,用途語,生産方法

• 外観

  無色〜黄褐色, 澄明の液体

• 溶解性

  水に微溶 (14g/L), メタノール, エーテルに可溶。

• 用途

  有機合成用溶剤及び中間体、消火器用

• 用途

  有機合成原料、溶剤。

• 化学的特性

  white to light yellow crystal powder

• 物理的性質

  Clear, colorless liquid with a sweet, chloroform-like odor

• 使用

  Bromochloromethane is used primarily as an extinguishing agent due to its oxygen-depleting properties.

• 定義

  ChEBI: A one-carbon compound substituted by a chloro and a bromo group.

• 一般的な説明

  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.

• 空気と水の反応

  Insoluble in water.

• 反応プロフィール

  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. .

• 危険性

  By inhalation.

• 健康ハザード

  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.

• 火災危険

  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.

• 安全性プロファイル

  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.

• 職業ばく露

  This compound is used in brominated flame retardants; a fire-extinguishing agent; and in organic synthesis

• 発がん性

  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).

• 環境運命予測

  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).

• 輸送方法

• 不和合性

  Incompatible with strong oxidizers (possible explosion), reducing agents, bases, carbonates, furyl alcohol, chemically active metals, such as calcium; base metals in the presence of moisture, powdered aluminum; zinc, magnesium. Liquid attacks some plastics, rubber, and coatings.
