Abstract:
A process for producing a halogenated phenol compound represented by the general formula [II]: ##STR6##wherein Q is a monovalent organic residue, A is, the same or different, a hydrogen atom, halogen atom, --SO.sub.3 H or --S.sub.3 Na group, or A at the ortho-position relative to Q may be combined with Q to form a divalent organic residue and X is a halogen atom including each isotope thereof, which comprises the step of reacting in a solvent a phenol compound represented by the general formula [I]: ##STR7##wherein X, Q and A have the same meanings as defined above, with a halide ion represented by the general formula X.sup.- wherein X has the same meanings as defined above, in the presence of a semiconductor catalyst with a photocatalytic activity under light irradiation conditions.
