ABSTRACT:
A method of making 2,4,5-trichlorophenol by chlorinating 2,5-dichlorophenol is characterized by reacting 2,5-dichlorophenol with chlorine in the presence of a liquid inert polar aprotic reaction medium such as nitrobenzene or a chlorinated hydrocarbon reaction medium, particularly 1,2-dichloroethane, and preferable a Lewis acid catalyst, particularly aluminium chloride. The product contains a higher ratio of 2,4,5-trichlorophenol to 2,3,6-trichlorophenol than has been obtainable previously.
