Abstract: | Liquid phase hydrodechlorination of chlorobenzene, 1,2,4-trichlorobenzene, hexachlorobenzene, polychlorinated biphenyls in the ethanol-containing solution, on Me0/C (where Me0-Pd, Ni or bimetallic Ni−Pd; C-carbon material “Sibunit”) with H2 have been studied at 20–70°C and PH 2=1–50 atm. Pd and Pd-promoted Ni catalysts exhibit the highest activity. Kinetic studies show hydrodechlorination of these compounds to be a consecutive reaction, which under the conditions described may produce less chlorinated compounds. |
