We studied the direct and indirect electrochemical reduction of hexachlorobenzene (HCB) by cyclic voltammetry in the presence of Co(II)Salen as catalyst in organic and aquo‐organic solutions. We also studied the degree of dechlorination of HCB by direct electrolysis under different experimental conditions (i.e., potential, organic‐water content, catalyst addition). Product analysis was performed by high‐pressure liquid chromatography using a UV detector (HPLC‐UV). The system containing the catalyst and water favors the HCB‐reduction kinetics and the generation of practically only 1,3‐dichlorobenzene, chlorobenzene, and benzene.
