CHLORINATION OF 2,4,6-TRICHLOROPHENOL IN ACIDIC AQUEOUS MEDIUM

The course of chlorination of 2,4,6-trichlorophenol (I) in water and approximately 20percent sulfuric and hydrochloric acids has been investigated.In all these media the reaction gives primarily 2,4,6,6-tetrachloro-2,4-cyclohexadienone (II) which is subsequently chlorinated under formation of polychlorinated alicyclic ketones or isomerized to give the more stable 2,4,4,6-tetrachloro-2,5-cyclohexadienone (III), the precursor of further arising chlorinated 1,4-benzoquinones.The ratio of the arising polychlorinated alicyclic ketones to chlorinated 1,4-benzoquinones is significantly influenced by concentration of hydrogen chloride in the reaction medium.On the basis of model experiments, the reaction mechanism of exhaustive chlorination of 2,4,6-trichlorophenol has been suggested.
