Kinetics and mechanism of oxidation of D-mannitol by potassium bromate in aqueous acidic medium
Kinetic investigation in Rh(III) catalyzed oxidation of D-Mannitol in an acidified solution of potassium bromate in the presence of Hg(OAc)2 as a scavenger, have been studied in the temperature range of 30 45 C. Increase in concentration of oxidant and H ion showed fractional positive order and fractional inverse order respectively. The influence of Hg(OAc)2, ionic strength and Cl ion on the ra...

15 صفحه اولA Study of the Kinetics and Mechanism of Oxidation of L -Ascorbic Acid by Permanganate Ion in Acidic Medium
The kinetics and mechanism of oxidation of L –Ascorbic acid by permanganate ion in acidic medium have been studied at 25±1°C, I = 1.0 mol dm (NaClO ), [H ] =1x10 mol dm .The stoichiometry was observed 3 + 2 3 4 to be 2:5 in terms of mole ratio of permanganate ions and ascorbic acid consumed. The reaction shows dependence on acid concentrations and is first order in both the oxidant and the redu...
متن کاملKinetics of nitrite oxidation by Nitrobacter winogradskyi.
Preliminary data on the kinetics of the oxidation of nitrite by Nitrobacter were presented by Laudelout & van Tichelen (1960). The present observations complete and extend the results concerning the effects of pH, concentrations of nitrite and of nitrate, temperature and oxygen partial pressure on the parameters of the rate equation for the oxidation of nitrite by intact cells and cell-free ext...
