Abstract: Kinetic study on the Oxidation of ethyl benzoate by N-chloro-3-methyl-2, 6- diphenylpiperidine-4-one in ethanol in acid medium has been carried out. The reaction follows first order kinetics, each in Ethyl benzoate, NCMDP and H+. The rate increased with increase in [H+] with fractional order. The effect of various anions on the rate of oxidation was found to be in the order SO42->Cl-. The effect of temperature on the rate of oxidation was studied by varying temperatures from 311K?325K.Based on the kinetic results and the product analysis, a suitable mechanism has been proposed for the reaction of NCMDP with Ethyl benzoate. The synthesized N-chloro-3-methyl-2, 6- diphenylpiperidine-4-one and the product obtained were characterized by IR Spectra.
