Abstract

A non-catalytic liquid phase chlorination of lower chlorinated beta-picolines comprising 3-trichloromethyl pyridine, 2-chloro-5-dichloromethyl pyridine, or mixtures thereof, to improve the yield of 2-chloro-5-trichloromethyl pyridine, an intermediate useful in the preparation of medicines and agricultural chemicals, especially herbicides.
