Notes:
The kinetics of the oxidation of diazepam (DZ) by Chloramine-B (CAB) has been studied in aqueous hydrochloric acid medium. The oxidation reaction follows the rate law:\documentclass{article}\pagestyle{empty}\begin{document}$ \it{-d[\rm{CAB}]\over\it dt_{\ .}}=k\rm{[CAB][DZ]^{0.6}[HCl]^{0.6}} $\end{document}The dependence of the reaction rate on temperature is studied and activation parameters for the rate-determining step are evaluated. The dielectric constant of the medium has a small effect on the rate. Ionic strength and the reaction product benzenesulfonamide have no effect on the reaction rate. The solvent isotope effect is studied. A probable mechanism for the observed kinetic data is proposed. © 1998 John Wiley & Sons, Inc. Int J Chem Kinet: 30: 605-611, 1998
