A Systematic Kinetic Study of Oxidation of p-Toluidine by Chromic Acid

Abstract

The oxidation kinetics of p-toluidine have been studied by chromic acid
in acetic acid-water medium. The orders in oxidant, substrate and H⁺ have
been obtained one in each. The primary salt effect on the rate of oxidation
is negligible. The effect of catalyst such as Ag⁺,  Cu²⁺ shows increasing
effect whereas Mn²⁺ has retarded the rate. Various thermodynamic
parameters have been evaluated. A probable mechanism has been suggested
on the basis of kinetic results.
