Cyclohexane solutions of several tri- and tetrachlorobiphenyls were photolyzed at 300 nm. The products obtained arose from dechlorination followed by hydrogen abstraction from the solvent. The reactivity of the compounds studied depended on the position of the chlorine substituents, ortho chlorines cleaving first and at a faster rate when para chlorines are present on the same ring. The quantum yields of the polychlorobiphenyls (PCB's) studied were determined.
