Kinetic and in situ infrared spectroscopic studies were
conducted to investigate the oxidation of different chlorinated benzenes (i.e., chlorobenzene,
1,2- 1,3-, and 1,4-dichlorobenzene) over V2O5/TiO2 catalysts. The oxidation of cyclohexyl
chloride and that of benzene were also examined for comparison. Observed differences in the
reaction rates and activation energies can be correlated to the structural differences of these
compounds, in light of a common reaction mechanism. This mechanism is supported by the results of
in situ FTIR studies, which indicate the presence of similar surface intermediates on the
catalyst surface under reaction conditions for all the aromatic compounds examined. The results
further suggest that the following two are the important mechanistic steps in the oxidation of
chlorinated benzenes: (1) the adsorption of the aromatic compound on the catalyst via a
nucleophilic attack on the chlorine position in the aromatic ring and (2) the subsequent
oxidation of the remaining aromatic ring. (C) 2004 Elsevier Inc. All rights reserved.
