摘要：
2,3,6-Trichloropyridine and 2,3,5,6-tetrachioropyridine are prepared by continuously reacting chlorine in the gas phase with one or more compounds such as 2,6-dichloropyridine and 2,3,6-trichloropyridine at a temperature of from about 200°C in the presence of an amount of catalyst effective to catalyze the reaction.
