ABSTRACT:
An improved method for the dechlorination of polychlorinated biphenyls that are dissolved in an organic solvent, which comprises the incremental additions of a hydrogen transfer agent, such as potassium formate, in the presence of a catalytic amount of a hydrogenation catalyst, such as palladium supported on carbon, and water.
