화학적 성질

Bromodichloromethane (BDCM) is a colorless, heavy, non-burnable/non-flammable liquid. It was formerly used as a flame retardant, a solvent for fats and waxes and because of its high density for mineral separation. Now, it is only used as a reagent or intermediate in organic chemistry. Small amounts of BDCM are also made in chemical plants for use in laboratories or in making other chemicals. On contact with hot surfaces or flames, BDMC decomposes forming toxic and corrosive gases, including hydrogen bromide and hydrogen chloride and reacts with strong bases, strong oxidants, and magnesium. BDMC is found in chlorinated drinking water as a consequence of the reaction between chlorine, added during water treatme

용도

As a chemical intermediate for organic synthesis and as a laboratory reagent; formerly used as a solvent and flame retardant. Currently, the major source of bromodichloromethane in the environment is from its formation as a by-product during chlorination of water.

정의

ChEBI: A one-carbon compound that is methane substituted by a bromo and two chloro groups. It occurs as a contaminant in drinking water.

일반 설명

Clear colorless liquid.

공기와 물의 반응

Slightly water soluble.

반응 프로필

BROMODICHLOROMETHANE may react with strong bases and magnesium. Incompatible with oxidizing materials .

건강위험

SYMPTOMS: Symptoms of exposure to BROMODICHLOROMETHANE may include irritation of the skin, eyes, mucous membranes and respiratory tract. It may also cause narcosis. Other symptoms may include nausea, dizziness and headache. It may also cause liver and kidney damage. Central nervous system effects may also occur.

화재위험

Literature sources indicate that BROMODICHLOROMETHANE is nonflammable.

Safety Profile

Confirmed carcinogen with experimental carcinogenic data. Moderately toxic by ingestion. Human mutation data reported. When heated to decomposition it emits very toxic fumes of Brand Cl-. See also CHLORINATED HYDROCARBONS, ALIPHATIC; and BROMIDES.

Carcinogenicity

Bromodichloromethane is reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity from studies in experimental animals.

환경귀착

Biological. Bromodichloromethane showed significant degradation with gradual adaptation in a static-culture flask-screening test (settled domestic wastewater inoculum) conducted at 25 °C. At concentrations of 5 and 10 mg/L, percent losses after 4 wk of incubation were 59 and 51, respectively. At a substrate concentration of 5 mg/L, 8% was lost due to volatilization after 10 d (Tabak et al., 1981).
Chemical/Physical. The estimated hydrolysis half-life in water at 25 °C and pH 7 is 137 yr (Mabey and Mill, 1978). Reported products of hydrolysis include carbon monoxide, hydrochloric and hydrobromic acids (Ellington et al., 1993; Kollig, 1993).
At influent concentrations of 1.0, 0.1, 0.01, and 0.001 mg/L, the GAC adsorption capacities at pH 5.3 were 7.9, 1.9, 0.47, and 0.12 mg/g, respectively (Dobbs and Cohen, 1980).
