디브로모클로로메탄 C화학적 특성, 용도, 생산

화학적 성질

clear light yellow to orange liquid

용도

A volatile halogenated methane present in trace amounts in drinking water as a result of the water treatment process. It is useful as chain transfer agents in PVC polymerization.

일반 설명

Clear colorless to yellow-orange liquid. Density 2.451 g / cm3. No flash point.

공기와 물의 반응

Insoluble in water.

반응 프로필

CHLORODIBROMOMETHANE is incompatible with strong bases, strong oxidizing agents and magnesium

건강위험

Chlorodibromomethane is a central nervous system (CNS) depressant at extremely high concentrations; it is toxic to the liver and kidneys of rodents and induces hepatocellular tumors in mice after long-term exposure.
In animal studies, the oral LD50 typically ranges between 800 and 1200 mg/kg.1,2 Acute signs of intoxication include sedation, flaccid muscle tone, ataxia, and prostration; death is due to CNS depression. In cases in which death does not occur until several days after acute exposure, hepatic and renal injury may be the cause of death.

화재위험

CHLORODIBROMOMETHANE is probably combustible.

Safety Profile

Moderately toxic by ingestion. Questionable carcinogen with experimental carcinogenic data. Human mutation data reported. Compounds of this type are generally irritating and narcotic. See also BROMOFORM and CHLOROFORM. When heated to decomposition it emits toxic fumes of Cland Br-.

잠재적 노출

Dibromochloromethane is used as a chemical intermediate in the manufacture of fire extinguishing agents; aerosol propellants; refrigerants, and pesticides. Dibromochloromethane has been detected in drinking water in the United States. It is believed to be formed by the haloform reaction that may occur during

환경귀착

Biological. Dibromochloromethane 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 39 and 25, respectively. At a substrate concentration of 5 mg/L, 16% was lost due to volatilization after 10 d (Tabak et al., 1981).
Surface Water. The estimated volatilization half-life of dibromochloromethane from rivers and streams is 45.9 h (Kaczmar et al., 1984).
Photolytic. Water containing 2,000 ng/μL of dibromochloromethane and colloidal platinum catalyst was irradiated with UV light. After 20 h, dibromochloromethane degraded to 80 ng/μL bromochloromethane, 22 ng/μL methyl chloride, and 1,050 ng/μL methane. A duplicate experiment was performed but 1 g zinc was added. After about 1 h, total degradation was achieved. Presumed transformation products include methane, bromide, and chloride ions (Wang and Tan, 1988).
Chemical/Physical. The estimated hydrolysis half-life in water at 25 °C and pH 7 is 274 yr (Mabey and Mill, 1978). Hydrogen gas was bubbled in an aqueous solution containing 18.8 μmol dibromochloromethane. After 24 h, only 18% of the dibromochloromethane reacted to form methane and minor traces of ethane. In the presence of colloidal platinum catalyst, the reaction proceeded at a much faster rate forming the same end products (Wang et al., 1988).
