ABSTRACT:
Direct and indirect oxidation of 1,5-diphenylcarbazide have been studied at hanging mercury drop electrode with differential pulse voltammetric technique. Direct oxidation of 1,5- diphenylcarbazide with KMnO4 resulted in formation of 1,5-diphenylcarbazone in the system at the reduction potential of –0.3 Volts. Oxidation study with K2Cr2O7 resulted in formation of 1,5-diphenylcarbazone at the reduction potential of -0.3 Volts along with formation of 1,5-diphenylcarbadiazone at the reduction potential of -0.6Volts in the system. Thus indicates that KMnO4 can be utilized for controlled step oxidation of 1,5- diphenylcarbazide, whereas, K2Cr2O7 can be utilized for maximum oxidation of 1,5-diphenylcarbazide. Indirect oxidation of 1,5-diphenylcarbazide was studied by dissolving 1,5-diphenylcarbazide in water mixed solvent systems for aerial oxidation due to formation of 1,5-diphenylcarbazone occurred and detected at the reduction potential of –0.3Volts.
