Abstract: | The acid-base equilibrium of hydrogen peroxide in aqueous solutions of CTAB and the reactivity of the peroxide anion toward
4-nitrophenyl diethylphosphate and 4-toluenesulfonate were studied. It was shown that the acid ionization rate constant of
hydrogen peroxide is increased by three times with increase in the CTAB concentration from 0 to 0.03 M. This makes it possible
to realize the decomposition of the substrates by their reaction with the peroxide anion at lower pH values in micellar cationic
systems than in aqueous solutions.
