Abstract

It is revealed that, in contrast to organic hydroperoxides, hydrogen peroxide (H2O2) is rapidly decomposed in a system of reverse micelles of sodium bis(2-ehylhexyl)sulfosuccinate (AOT) in n-decane. The yield of free radicals upon the decomposition of H2O2 in a system of reverse micelles upon the interaction between AOT and cobalt acetyl acetonate (Co(acac)2) is studied by the inhibitor method using an original spin trap. It is established that the interaction between H2O2 and AOT proceeds with no radical formation. Co(acac)2 catalyses the radical decomposition of H2O2 in an aqueous solution. In micellar AOT solutions in n-decane, H2O2 and Co(acac)2 in practice do not react, because H2O2 is localized in a micelle water pool, Co(acac)2 and the spin trap, in the organic phase. In this case, the generation of radicals is not observed.
