| Résumé : | Kinetic data for the oxidation of 2-aminopentanedioic acid/L-glutamic acid (Glu-e) by quinolinium dichromate (QDC) in perchloric acid medium are reported. The results of the reactions studied spectrophotometrically over a wide range of experimental conditions show that the rate of the reaction is increased by increases in perchloric acid, the ionic strength, and the concentration of Glu-e. The reactions are first order with respect to both QDC and Glu-e. Added products are found to have an insignificant effect on the reaction rate. The activation parameters and thermodynamics have been evaluated and lend further support to the proposed mechanism. |
