In a process of halogenation of benzene or benzenenderivatives, di-substituted halobenzene derivatives havingnpara-aromatic compounds or tri-substituted halobenzenenderivatives having 1,2,4-substituted aromatic compounds arenselectively produced. In halogenation of benzene or benzenenderivatives, a fluorine-containing zeolite catalyst such asnL-type zeolite, or a zeolite catalyst having the crystal sizenof at most 100 nm is used. The reaction is preferably effectednin the presence of a solvent, and the solvent is preferably anhalogenated compound. |
