Kinetics of oxidation of m-Toluidine by Sodium Dichromate 

By Ritu Singh, Farhat Hasan Khan, Mahboob Alam and Firoz Ahmad 


The Oxidation of m-toluidine by sodium dichromate has been studied both spectrophotometrically (640nm) and iodometrically in aqueous nitric acid medium. The reaction is said to follow consecutive reaction mechanism. The reaction shows substrate inhibition at low H+ concentration. Oxidation proceeds by two routes and both routes give the colored product. Suitable mechanism is proposed. The rate constants, equilibrium constants and kinetic parameters are calculated. 

Key word:   Kinetics, Oxidation, Catalyst, m-toluidine, Sodium Dichromate.
