Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). ?) 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.
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 ...
Picric acid is an organic compound with the formula (O 2 N) 3 C 6 H 2 OH. Its IUPAC name is 2,4,6-trinitrophenol (TNP). The name "picric" comes from Greek: πικρός (pikros), meaning "bitter", due to its bitter taste. It is one of the most acidic phenols.
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 ...
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 ...

2,6-Di- tert -butylphenol is prepared industrially via the Friedel–Crafts alkylation of phenol with isobutene catalyzed by aluminium phenoxide: C 6 H 5 OH + 2 CH 2 =C (CH 3) 2 → ( (CH 3) 3 C) 2 C 6 H 3 OH. In this way, approximately 2.5M kg/y are produced. [2] Alkylation of phenol usually favours the para-position, and a strong lewis acid ...
The synthetic fuel is extremely clear because of the near-total absence of sulfur and aromatics. Synthetic fuel or synfuel is a liquid fuel, or sometimes gaseous fuel, obtained from syngas, a mixture of carbon monoxide and hydrogen, in which the syngas was derived from gasification of solid feedstocks such as coal or biomass or by reforming of ...
