Abstract

Kinetics of oxidation of diethylamine (DEA) by Bromamine-B (BAB) has been investigated at 303 K in acid solution with Ru(III) as catalyst. The oxidation behavior obeys the rate law, rate = k BAB] DEA] Ru(III)] H+](-x) where `x' is less than unity indicating retardation of rate by H+]. Added halide ions, the reaction product benzenesulphonamide, variation of ionic strength and dielectric constant of the medium do not have any significant effect on the rate. The protonation constant of monobromamine-B evaluated for the reaction is 32.3 at 303 K. Activation parameters have been evaluated from Arrhenius plot. A mechanism consistent with experimental results has been proposed. (C) 1999 John Wiley & Sons, Inc.
