The invention concerns a halogenation in position meta of a phenol function.
Then, the tefluthrin can be produced from 2,3,5,6-tetrafluorodimethylolbenzene via halogenation, hydrogenation and esterification.
A photocatalyst is obtained by halogenation of a glass fiber with silicon dioxide in the composition thereof.
This invention provides a process for theN-halogenation of at least one 5-hydrocarbyl hydantoin and/or at least one 5,5-dihydrocarbyl hydantoin.
Alkanes react with halogens in a so-called free radical halogenation reaction.
Diaryl halophosphates are prepared by halogenating an alkyl diaryl phosphite.

Reactions of Alkanes: Bond-Dissociation Energies, Radical Halogenation, and Relative Reactivity
The water layer is then separated from the partially dissolved rubber cement and the cement phase is sent for halogenation.
Free radical halogenation reactions occur with halogens, leading to the production of haloalkanes.
The oxide is produced by halogenating a copper oxide of the formula An+1CunO2n+1, where A and n are as defined above.
