Liquid cyclopentadiene and chlorine are diluted in a polychlorocyclopentane solvent, reacting to form tetrachlorocyclopentane. The tetrachlorocyclopentane is then passed through an illuminated zone where gaseous chlorine is injected, effecting photochemical chlorination of the organic feed to form a hexachlorocyclopentane product. A portion of the circulating stream leaving the reaction zone is withdrawn as product of the reaction zone, the remainder being recirculated to provide the solvent for the conversion phase of cyclopentadiene and chlorine to tetrachlorocyclopentane.
