Abstract: Pentachlorophenol is prepared by chlorination of other chlorophenols, especially dichlorophenols, trichlorophenols and tetrachlorophenols, with gaseous chlorine, in the presence of a gallium halide. Pentachlorophenol is used as a fungicide and as a wood preservative.

Abstract: The invention relates to a process for the bromination of the aromatic ring of phenols or substituted phenols containing ethylenic chains. The process is characterised in that a compound of formula: in which n is 0 or an integer, R1 and R2 are identical or different and represent a hydrogen, a halogen, or an alkyl, alkoxy, acyloxy or formyl radical, it being possible for R1 and R2 to form a methylenedioxy bridge, and R3 and R4 are identical or different and can be hydrogens or alkyl radicals, is reacted with a reagent comprising at least one N-Br bond.

Abstract: A process for the chlorination, using gaseous chlorine, of phenolic compounds substituted in an ortho position relative to the hydroxyl function group. More precisely, it is a process for the chlorination of these phenolic compounds in the molten state or in a solvent medium, using gaseous chlorine, in the presence of an organic cation. The process is applicable especially to the chlorination of 2,6- dichlorophenol to 2,4,6-trichlorophenol.

Abstract: The chloronitrophenols, e.g., 2,6-dichloro-4-nitrophenol (a known agrochemical/pharmaceutical intermediate), are efficiently prepared by chlorinating ortho- or para-nitrophenol with gaseous chlorine, characteristically in the molten state, and in the presence of a catalytically effective amount of a primary, secondary or tertiary amine.

Abstract: The chlorophenols, e.g., 2,4,6-trichlorophenol, are efficiently prepared by chlorinating an ortho-/para-substituted phenolic compound with gaseous chlorine, whether in molten state or in a solvent reaction medium, in the presence of a catalytically effective amount of a primary, secondary or tertiary amine.
