Dechlorination of polychlorobenzenes over Fe3O4 was investigated by a pulse micro-reactor technique.Dechlorinations of various polychlorobenzenes in hexane and cyclohexane were carried out in the gas phase at the temperatures ranging from 498 to 623 K.In the presence of such hydrogen donating solvents, dechlorination was shown to proceed almost exclusively.The relative rates of dechlorination were measured by gas chromatography.It was found that the solvents used to dissolve polychlorobenzenes plays a role of a hydrogen donor in this reaction.The different rates among unequivalent chlorine atoms in a molecule were interpreted by the effect of steric acceleration caused by the neighboring chlorine atom(s).The reaction will probably proceed via hydrogenolytic cleavage of C-Cl bonds.
