Dibromochloromethane is a colorless to yellow, heavy and nonflammable compound with formula CHBr 2 Cl. [1] [2] It is a trihalomethane. The substance has a sweet odour ...
Bromodichloromethane is a trihalomethane with formula C H Br Cl 2.It is a colorless, nonflammable liquid which will dissolve in water, or evaporate in air. [1] Most of the chemical is produced through the chlorine disinfection process, [1] and as a result it can occur in municipally-treated drinking water. [2]
The EPA limits the total concentration of the four chief constituents (chloroform, bromoform, bromodichloromethane, and dibromochloromethane), referred to as total trihalomethanes (TTHM), to 80 parts per billion in treated water. [6] Traces of chloroform are produced in swimming pools. [7] [8] [9] [10]
Bromochloromethane or methylene bromochloride and Halon 1011 is a mixed halomethane.It is a heavy low-viscosity liquid with refractive index 1.4808.. Halon 1011 was invented for use in fire extinguishers in Germany during the mid-1940s, in an attempt to create a less toxic, more effective alternative to carbon tetrachloride.
Dibromomethane is prepared commercially from dichloromethane via bromochloromethane: . 6 CH 2 Cl 2 + 3 Br 2 + 2 Al → 6 CH 2 BrCl + 2 AlCl 3 CH 2 Cl 2 + HBr → CH 2 BrCl + HCl. The latter route requires aluminium trichloride as a catalyst. [3]
Chronic exposure of both bromoform and dibromochloromethane can cause liver and kidney cancer, as well as heart disease, unconsciousness, or death in high doses. [19] Due to the potential carcinogenicity of these compounds, drinking water regulations across the developed world require regular monitoring of the concentration of these compounds ...
1,2-Dibromo-3-chloropropane (dibromochloropropane), better known as DBCP, is the organic compound with the formula BrCH(CH 2 Br)(CH 2 Cl). It is a dense colorless liquid although commercial samples often appear amber or even brown.
While dichloromethane extract was the most potent bioactive, reducing methane production by 79%, bromoform and dibromochloromethane had the highest activity inhibiting methane production, and only bromoform is present in sufficient quantities to be effective. [12]
