Kinetics and mechanism of oxidation of pyruvic acid by peroxomonophosphate in acid perchlorate medium
2008
Kinetics of oxidation of pyruvic acid by peroxomonophosphate (PMP) has been studied in a wider pH range. The stoichiometry corresponds to the reaction as represented by the eq. (1) CH 3 COCO 2 H + H 3 PO 5 → CH 3 CO 2 H + H 3 PO 4 (1) The pattern of reactivity of peroxomonophosphate species has been delineated. A plausible reaction mechanism is suggested. The energy and entropy of activation were calculated to be (72 ± 7) kJ mol -1 and (-40 ± 4) JK -1 mol -1 respectively.
