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.
The monohalomethanes are organic compounds in which a hydrogen atom in methane is replaced by a halogen. They belong to the haloalkanes or to the subgroup of halomethanes. The four common [a] members are fluoromethane, chloromethane, bromomethane and iodomethane. Historical name for this group is methyl halides; it's still widely used.
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
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 ...
The separation of nitrogen or oxygen from air (generally only up to 99.5%) Separation of hydrogen from gases like nitrogen and methane; Recovery of hydrogen from product streams of ammonia plants; Recovery of hydrogen in oil refinery processes; Separation of methane from the other components of biogas
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]
If methane is detected (by using a spectrometer for example) this may indicate that life is, or recently was, present. This was debated [ 25 ] when methane was discovered in the Martian atmosphere by M.J. Mumma of NASA's Goddard Flight Center, and verified by the Mars Express Orbiter (2004) [ 26 ] and in Titan 's atmosphere by the Huygens probe ...
