Abstract

The oxidation of l-alanine and l-leucine with 1,3-dichloro-5,5-dimethylhydantoin (DCDMH) was investigated in aqueous acetic acid medium at 303 K. The reactions follow pseudo first-order kinetics each in [DCDMH] and [l-amino acids]. The reaction was observed acid catalysed. The study completely discarded the formation of complex and the involvement of free radicals. The study reveals that the reaction velocity retarted with increase in solvent composition. Thermodynamic parameters were computed. A suitable mechanism consistent with kinetic results has been proposed.
