OXIDATION OF ORTHO AMINOBENZYL ALCOHOL: A CONCISE KINETIC STUDY

The foremost objective of the present work is to get a deep insight into the kinetics of ortho aminobenzyl alcohol (OABAlc) to develop a simple, efficient, and cost-effective method for its detection in contaminated water samples.This work deals with the silver catalyzed oxidation of OABAlc by potassium persulphate.The rate of oxidative reaction was determined by kinetic spectrophotometric method with absorption maxima of the reaction mixture at 440 nm, at constant pH and temperature of the solution.The effect of substrate, oxidant, catalyst, pH, temperature, ionic strength, and dielectric constant in this reaction has also been studied.During the investigation of thermodynamic parameters, the activation energy was found to be 58.92kJ/mol, activation entropy = -53.61,activation enthalpy = 56.25 kJ/mol, and free energy = 73.43kJ/mol.The results manifest first-order kinetics of the reaction concerning substrate, oxidant, and catalyst at optimum pH 7.0 and 40 0 C temperature.To explore further application and importance of OABAlc, a study on various aspects of the oxidation reaction is carried out in the presence of Ag (I) as a catalyst and a strong oxidant potassium persulphate to get deep insight into the chemical aspects of the compound and to deduce the mechanism of reaction under study.
