Kinetics and Mechanism of Acid Bromate Oxidation of2-Hydroxy-1-naphthalideneanil

Abstract

The kinetics of oxidation of the Schiff base, 2-hydroxy-1-naphthalideneanil

by potassium bromate in aquo-acetic acid medium has

been studied. The reaction is found to obey the first order rate

equation. The study is carried out at five different temperatures.

The study is also undertaken by change in the concentration of

oxidant, change in the concentration of HClO₄ and change in ionic

strength. These changes also show first order behaviour. The thermodynamic

parameters ΔE, ΔH*, ΔG* and ΔS* have been calculated

and reported. The frequency factor (A) is also computed. Ionic

strength effects show a negative effect on rate constant.
