  • Abstract

    Kinetics of the oxidation of 3-benzoylpropionic acid (KA) by N-chloroacetamide (NCA)in aqueous acetic acid medium has been studied. The reaction followed potentiometrically at 298K. The effects of temperature, composition of solvent medium and concentration of added mineral acid on the rate of reaction were also studied. The reaction exhibits first order each [KA], [NCA] and hydrogen ions. Variation in ionic strength has no effect on the reaction rate, while the reaction rates are enhanced on lowering the dielectric constant of the reaction medium. There is no effect of added acetamide. Protonated NBB has been postulated as the reactive oxidizing species. The mechanism proposed involves the attack of the H2O+Cl on the enol form of the 4-oxo acid
