The quantitative analysis of the microemulsions dissolved hydrogen peroxide has been worked out for concentrations ranging from 8 M to 10 to the -7th M. The stability of microemulsion containing sodium laurate, sodium dodecyl sulfate and benzyl-dimethyl-tetradecylammonium chloride as surfactants, n-butanol and t-butanol as cosurfactants as well as cyclohexane and water towards hydrogen peroxide has been investigated by kinetic measurements. These investigations involve the volumetric analysis of the oxygen evolution and the determination of the total consumption of hydrogen calling for an efficient trapping of hydroxyl radicals by the cosurfactants. The results imply that microemulsion containing SDS are of maximum stability equivalent to that of aqueous solutions of hydrogen peroxide and might be used as a reaction medium for non-catalyzed oxidation reactions not involving hydroxyl radicals.
