Kinetics of Oxidation of 2-Hydroxy-l-Naphthalidene Anil and Substituted Anils by Ce⁴⁺ → Ce³⁺ Redox System in Aqueous Sulphuric Acid Medium.

The kinetics of oxidation of the Schiff base 2-hydroxy -1 -Naphthalidene anil and substituted anils such as 2′ -methoxy -2 -hydroxy -1 -naphthalidene anil, 3′ -Methoxy -2 -Hydroxy -1 -Naphthalidene anil and 4′ -Methoxy -2 -Hydroxy -1-Naphthalidene anil by Ce (IV) as oxidant in aqueous sulphuric acid medium. The kinetic study is carried out by using various concentrations of oxidants and the substrates, which is found to be the first order reaction. A suitable plaussible mechanism has been suggested on the basis of kinetic results.
