Kinetics of Oxidation of Indole in High Indole Concentration Range by Bromamine-B in Alkaline Medium Catalysed by Os(VIII)

Abstract

The kinetics of oxidation of indole (In) in bigh indole concentration
range by sodium N-bromobenzene sulphonamide (BAB) in
alkaline medium in presence of O_SO₄ catalyst have been investigated
at 30°C. The reaction rate shows a first order dependence
of rate on [BAB]_o and [Indole], and inverse first order dependence
of rate on [OH^- ] and first order on [O_SO₄]. Addition of halide ions
and variation of ionic strength and dielectric constant of the medium
do not have any sigtlflcant effect on the reaction rate. Thermodynamic
parameters have been evaluated.
