Bromomethane, commonly known as methyl bromide, is an organobromine compound with formula C H 3 Br. This colorless, odorless, nonflammable gas is produced both industrially and biologically. This colorless, odorless, nonflammable gas is produced both industrially and biologically.
Bromoform was discovered in 1832 by Löwig who distilled a mixture of bromal and potassium hydroxide, as analogous to preparation of chloroform from chloral. [5]Bromoform can be prepared by the haloform reaction using acetone and sodium hypobromite, by the electrolysis of potassium bromide in ethanol, or by treating chloroform with aluminium bromide.
Soil gases (soil atmosphere [1]) are the gases found in the air space between soil components. The spaces between the solid soil particles, if they do not contain water, are filled with air. The primary soil gases are nitrogen, carbon dioxide and oxygen. [2] Oxygen is critical because it allows for respiration of both plant roots and soil ...
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]
CBr 4 can be obtained by the bromination of methane. The byproducts include other brominated methanes (methyl bromide, dibromomethane and bromoform) and hydrogen bromide. This process is analogous to the chlorination of methane: Br 2 + hν → 2 Br·; Br· + CH 4 → ·CH 3 + HBr. ·CH 3 + Br 2 → CH 3 Br + Br·. CH 3 Br + Br· → ·CH 2 Br ...
Halocarbon compounds are chemical compounds in which one or more carbon atoms are linked by covalent bonds with one or more halogen atoms (fluorine, chlorine, bromine or iodine – group 17) resulting in the formation of organofluorine compounds, organochlorine compounds, organobromine compounds, and organoiodine compounds.
The preparation of EtBr stands as a model for the synthesis of bromoalkanes in general. It is usually prepared by the addition of hydrogen bromide to ethene: . H 2 C=CH 2 + HBr → H 3 C-CH 2 Br
Some organisms can oxidize methane, functionally reversing the process of methanogenesis, also referred to as the anaerobic oxidation of methane (AOM). Organisms performing AOM have been found in multiple marine and freshwater environments including methane seeps, hydrothermal vents, coastal sediments and sulfate-methane transition zones. [8]
