Bromoethane is inexpensive and would rarely be prepared in the laboratory. A laboratory synthesis includes reacting ethanol with a mixture of hydrobromic and sulfuric acids . An alternate route involves refluxing ethanol with phosphorus and bromine ; phosphorus tribromide is generated in situ .

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]
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.

The latter reaction is also viable laboratory synthesis. One laboratory technique for substitutive bromination treats propanol with a mixture of hydrobromic and sulfuric acids: CH 3 CH 2 CH 2 OH + HBr → CH 3 CH 2 CH 2 Br + H 2 O. Alternate synthetic routes include treating propanol with phosphorus tribromide [4] or via a Hunsdiecker reaction ...
