摘要：

Oxidation with potassium dichromate in perchloric acid medium of the alkanols 1-butanol, 1-hexanol, and 1-octanol, components of sodium dodecyl sulfate reverse micelles in alkanols, has been studied. The reaction rate is first-order with respect to Cr(VI) and depends linearly on the HClO4 concentration in the aqueous phase, but the reaction rate decreases with the amount of alcohol in the reverse micelles. To explain the kinetic results it is necessary to consider the intermicellar exchange of the reactants, which could depend on the thickness of the layer where the surfactant and the alcohol are located.
