Halogenation of benzene where X is the halogen, catalyst represents the catalyst (if needed) and HX represents the protonated base. A few types of aromatic compounds, such as phenol, will react without a catalyst, but for typical benzene derivatives with less reactive substrates, a Lewis acid is required as a catalyst.
According to the original usage [1] and work carried out on cellular stress mechanisms and responses, [2] [3] [4] chaotropic substances do not necessarily disorder the structure of water. [5] The chaotropic activities of solutes in the aqueous phase (e.g. ethanol, butanol, urea, MgCl 2, and phenol) have been quantified using an agar-gelation ...
A tetrachlorophenol is any organochloride of phenol that contains four covalently bonded chlorine atoms. Tetrachlorophenols are produced by electrophilic halogenation of phenol with chlorine. [1] Different isomers of tetrachlorophenol exist according to which ring positions on the phenol contain chlorine atoms. There are three different isomers:
A chlorophenol is any organochloride of phenol that contains one or more covalently bonded chlorine atoms. There are five basic types of chlorophenols (mono- to pentachlorophenol) and 19 different chlorophenols in total when positional isomerism is taken into account. Chlorophenols are produced by electrophilic halogenation of phenol with ...
In chemistry, halogenation is a chemical reaction which introduces one or more halogens into a chemical compound. Halide-containing compounds are pervasive, making this type of transformation important, e.g. in the production of polymers, drugs. [1] This kind of conversion is in fact so common that a comprehensive overview is challenging.
The most widely practised example of this reaction is the ethylation of benzene. Approximately 24,700,000 tons were produced in 1999. [2] (After dehydrogenation and polymerization, the commodity plastic polystyrene is produced.) In this process, acids are used as catalyst to generate the incipient carbocation. Many other electrophilic reactions ...

An iodophenol is any organoiodide of phenol that contains one or more covalently bonded iodine atoms. There are five basic types of iodophenols (mono- to pentaiodophenol) and 19 different iodophenols in total when positional isomerism is taken into account. Iodophenols are produced by electrophilic halogenation of phenol with iodine.
