A Kinetic and Mechanistic Study of Palladium (II) Catalysed Oxidation of Arginine by Cerium (IV) in Acid Media
Year: 2015
Type: article
Abstract: Kinetics of palladium(II) catalysed oxidation of arginine has been studied by Ce(IV) in acidic medium at 45°C.The reaction show first order kinetics with respect to Ce(IV) and Pd(II) in the oxidation of arginine.The first order kinetics with respect to arginine obtained at its lower concentration changes to zero order at its higher concentration.It is found that pseudo first order rate constant, k obs decreases with increase of [HSO 4 -] and increases with the increase of [H + ].Various activation parameters have been calculated with the pseudo first order rate constant values observed at three different temperatures.A plausible mechanism has been proposed from the results of kinetic studies, reaction stoichiometry and product analysis.
