Kinetics and mechanism of oxidation of methylphenyl sulfide by hydrogen peroxide catalyzed by bicarbonate ammonium were studied. The main parameters of the catalytic process - binding constants of Н2О2, HCO4- anion and the substrate by micellar surface, and second order rate constants in oxidation of methylphenylsulfide in micellar phase - were determined from the pseudophase model of micellar catalysis.


Key word oxidation, micellar catalysis, hydrogen peroxide, peroxohydro carbonate anion.
