A method for preparing triclorometoxibenceno with chlorination reduced ring.

摘要

A method for preparing a triclorometoxibenceno from metoxibenceno or metoxibenceno partially chlorinated, such as anisole or P - cloroanisol, containing at least 20 ppm of phenol.The phenol concentration was reduced to less than 20 ppm and prepares a mixture of metoxibenceno radicaleslibres with a source of chlorine, such as Chlorine or SULFURYL CHLORIDE.The reaction is conducted in a Solvent, which can be benzotrifluoruro, ortoclorobenzotrifluoruro, metaclorobenzotrifluoruro, paraclorobenzotrifluoruro, or a diclorobenzotrifluoruro.The mixture is exposed to Actinic Radiation such as Ultraviolet Light, which generates Free Radicals of chlorine.
