Abstract A simple and efficient method for the perchlorination of polychlorinated biphenyls (PCBs) to decachlorobiphenyl, using antimony pentachloride, is described. Average yields of decachlorobiphenyl from 3 individual samples of Aroclors 1016 and 1254 were 85 and 104%, respectively. Bromine was identified as a contaminant in certain lots of antimony pentachloride. PCB perchlorinations with bromide-contaminated antimony pentachloride resulted in significant amounts of bromononachlorobiphenyl.
