Kinetics of Oxidation of p-Chloro Aniline by Chromic Acid

Abstract

Kinetics of oxidation of p-dhloro aniline by chromic acid in 10 % acetic  acid-water medium have been reported for the first time. The rate of reaction is proportional to the first power of concentration of oxidant and substrate, i.e., amine. The order of reaction with H⁺ is one in each case. The reaction velocity increases by increasing percentage composition of  acetic acid. The addition of neutral salt on the reaction mixture shows no effect on the reaction rate. The study reveals that the rate of reaction is increased by addition of  Ag⁺ and Cu²⁺ whereas retarded by Mn²⁺. Various activation Parameters have been computed. Based on above finding a probable reaction mechanism has been proposed. The final product is p,p' -dichloro azohenzene.
