Abstract

The kinetics of the oxidation of o-toluidine by chloramine-B CAB] has been studied in aqueous sulfuric rid at 303 K. The rate shows first Order dependence on CAB], fractional order in o-toluidine] and inverse first order in H+]. The variation of ionic strength, change in dielectric constant of the medium, addition of the reaction product (benzene sulphonamide) and halide ions had no significant effect on the reaction rate. The oxidation product has been identified as o,o'-dimethylazobenzene. Thermodynamic parameters were evaluated. The protonation constant of monochloramine-B has been evaluated to be 64.5 +/- 3.
