2,4,6-Tribromophenol (TBP) is a brominated derivative of phenol. It is used as a fungicide , as a wood preservative, and an intermediate in the preparation of flame retardants . Production
Bromophenol. A bromophenol is an organic compound consisting of hydroxyl groups and bromine atoms bonded to a benzene ring. They may be viewed as hydroxyl derivatives of bromobenzene, or as brominated derivatives of phenol. There are five basic types of bromophenols (mono- to pentabromophenol) and 19 different bromophenols in total when ...
The formation of a brominated phenol (i.e. 2,4,6-tribromophenol) or aniline (i.e. 2,4,6-tribromoaniline) in form of a white precipitate indicates that the unknown was a phenol or aniline. The more unsaturated an unknown is, the more bromine it reacts with, and the less coloured the solution will appear.
2,4,6-Trichlorophenol, also known as TCP, phenaclor, Dowicide 2S, Dowcide 2S, omal, is a chlorinated phenol that has been used as a fungicide, herbicide, insecticide, antiseptic, [3] defoliant, and glue preservative. [4] It is a clear to yellowish crystalline solid with a strong, phenolic odor. It decomposes on heating to produce toxic and ...
Hydrogen bromide prepared by the above methods can be contaminated with Br 2, which can be removed by passing the gas through a solution of phenol at room temperature in tetrachloromethane or other suitable solvent (producing 2,4,6-tribromophenol and generating more HBr in the process) or through copper turnings or copper gauze at high ...
The regiochemistry of halogenation changes in strongly acidic solutions where PhOH 2] + predominates. Phenol reacts with dilute nitric acid at room temperature to give a mixture of 2-nitrophenol and 4-nitrophenol while with concentrated nitric acid, additional nitro groups are introduced, e.g. to give 2,4,6-trinitrophenol.
The reaction in figure 2 shows the reductive debromination of 2,4,6-tribromophenol (2,4,6-TBP) by Ochrabactrum. [13] Based on the relative degradation of the molecule along with analytical results, it has been postulated that degradation of 2,4,6-TBP proceeds through debromination of ortho -bromine in the first step by a dehalogenase to yield 2 ...
The monobromophenols are chemical compounds consisting of phenol substituted with a bromine atom. There are three isomers, 2-bromophenol, 3-bromophenol, and 4-bromophenol. Bromophenols. IUPAC name. 2-Bromophenol. 3-Bromophenol.
