Abstract:

The kinetics of oxidation of DL- Aspartic Acid by Chromic Acid has been studied in the presence of Sulphuric Acid at 29oC. The reaction follows first order kinetics with respect to each [DL-Aspartic Acid], [Chromic Acid] and [H+]. Oswald isolation method is used for study of rate of reaction. With increase in the concentration of Sulphuric Acid the rate constant of the system increased. The probable products are acetaldehyde, CO2 and ammonia. A tentative mechanism involving C-C bond fission based on experimental observations has been proposed. The rate constant, catalytic constant, dielectric constant, pH value and temperature coefficient have been determined for all the runs. A mechanism consistent with results obtained has been proposed with the following rate equation:
d [Cr (VI)] / dt = k [Cr (VI) ] [DL-Aspartic Acid] [H+]
