Reaction Steps

at 96.75 percent pentachloropyridine conversion. Of the metallic zinc used in the reaction, 95.61 percent reacts with chloropyridine with 91.71 percent resulting in the formation of 2,3,5,6-tetrachloropyridine. Of the metallic zinc added, 100 percent oxidizes during the reaction with 99.16 percent of it accounted for in the final products.
