Kinetics of Oxidation of 2-Hydroxy-1-Naphthalidene-anil by Ce(IV) in Aqueous Sulphuric Acid

Abstract

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

has been studied by Ce⁴⁺ → Ce³⁺ redox system in

aquo-sulphuric acid medium. The reaction is found to obey the first

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

The thermodynamic parameters ΔH, ΔG, ΔE and ΔS have

been calculated. The frequency factor (A) is also determined and

reported. The kinetic study is also carried out at various concentrations

of oxidant and Schiff base which is also found to be the first

order reaction. The effect of ionic strength on the reaction is also

studied. A suitable possible mechanism has been suggested on the

basis of kinetic results.
