ABSTRACT:
Tetrachloropyridine is prepared by heating pentachloropyridine in an aqueous medium under pressure, with agitation, in the presence of a particulate oxidizable metal, e.g., zinc and a hydrogen-producing acid, e.g., hydrogen chloride. The tetrachloropyridine is then conveniently extracted with an inert, water-immiscible solvent, e.g., a halogenated hydrocarbon.
