Abstract

Un método para preparar un triclorometoxibenceno a partir de metoxibenceno o metoxibenceno parcialmente clorado, tales como anisol o p-cloroanisol, quecontiene al menos 20 ppm de fenol. La concentracion de fenol es reducida a menos de 20 ppm y se prepara una mezcla de metoxibenceno con una fuente de radicaleslibres de cloro, tal como cloro o cloruro de sulfurilo. La reaccion es realizada en un solvente, que puede ser benzotrifluoruro, ortoclorobenzotrifluoruro,metaclorobenzotrifluoruro, paraclorobenzotrifluoruro, o un diclorobenzotrifluoruro. La mezcla es expuesta a una radiacion actínica, tal como luz ultravioleta,que genera los radicales libres de cloro.A method for preparing a trichloromethoxybenzene from partially chlorinated methoxybenzene or methoxybenzene, such as anisole or p-chloroanisole, which contains at least 20 ppm of phenol. The phenol concentration is reduced to less than 20 ppm and a mixture of methoxybenzene with a source of chlorine free radicals, such as chlorine or sulfuryl chloride, is prepared. The reaction is carried out in a solvent, which may be benzotrifluoride, orthochlorobenzotrifluoride, methachlorobenzotrifluoride, parachlorobenzotrifluoride, or a dichlorobenzotrifluoride. The mixture is exposed to actinic radiation, such as ultraviolet light, which generates chlorine free radicals.
