Kinetics of oxidation of mixture of glycine + anthranilic acid by chromic acid in presence of sulphuric acid have been studied. The probable products are benzoic acid, formaldehyde, ammonia and carbon dioxide. The rate of oxidation increase with increase in the concentration of sulphuric acid. Ostwald isolation method is used for study the rate of the reaction. The rate of reaction with respect to hydrogen ion is one. Kinetics of oxidation of mixture of glycine + anthranilic acid by chromic acid shows first order reaction. The kinetic parameters such as energy of activation, catalytic constant, temperature coefficient are calculated.
