Kinetics of the oxidation of diethyl sulfide in aqueous H2O2–Na2SiO3 solutions

A study of the effect of sodium silicate (Na2SiO3) on the kinetics of the oxidation of diethyl sulfide (Et2S) by hydrogen peroxide in aqueous solution in a broad pH range has shown that the active species in the pathway catalyzed by this silicate are peroxopolysilicate anions. We determined the pero...

Beschreibung
Zusammenfassung:	A study of the effect of sodium silicate (Na2SiO3) on the kinetics of the oxidation of diethyl sulfide (Et2S) by hydrogen peroxide in aqueous solution in a broad pH range has shown that the active species in the pathway catalyzed by this silicate are peroxopolysilicate anions. We determined the peroxopolysilicate stability constant (1.4 L/mol) and rate constant of the reaction of this species with Et2S (0.15-0.3 L/mol·s).
