Although natural TBP has been identified in ocean sediments as a metabolite of marine fauna, [5] the commercial product is prepared industrially. In 2001, the production volume of TBP was estimated to be 2500 tonnes/year in Japan and 9500 tonnes/year worldwide. [2] TBP can be prepared by the controlled reaction of elemental bromine with phenol: [3]
Infobox references. 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 ...
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 positional isomerism ...
Properties. 2,4,6-Tri- tert -butylphenol is a white solid which dissolves in many organic solvents, but not in aqueous or alcoholic alkaline solutions. The green-blue coloring with iron (III)chloride, which is characteristic for phenols, does not occur in 2,4,6-TTBP. The compound is oxidizable in air but practically non-biodegradable.
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 ...
Properties. At room temperature, 2,4-dibromophenol is a solid with needle-like crystals. It melts at 38 °C (100.4 °F) and boils at 238.5 °C (461.3 °F). it has a molecular weight of 251.905 g/mol. It is soluble in water, ethanol, ether and benzene and slightly soluble in carbon tetrachloride.
2,4,6-Tribromoaniline. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). 2,4,6-Tribromoaniline is a brominated derivative of aniline with the formula C 6 H 4 Br 3 N. It is used in organic synthesis of pharmaceuticals, agrochemicals and fire-extinguishing agents.
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 ...
