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 ...
Presence of unsaturation and/or phenol or aniline in the sample is shown by disappearance of the deep brown coloration of bromine when it has reacted with the unknown sample. 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 ...
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 temperature.
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 ...
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 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.
2,4,6-Tribromoanisole ( TBA) is a chemical compound that is a brominated derivative of anisole. It is one of the chemicals responsible for cork taint. [ 2] Tribromoanisole is a fungal metabolite of 2,4,6-tribromophenol, which is used as a fungicide. It can be found in minute traces on packaging materials stored in the presence of fiberboard ...
