• Resumen

  • An inactive premicellar/micellar {Surfactant-MnO4-} aggregate has been found to inhibit the rate of oxidation of disaccharides viz. maltose and lactose by alkaline KMnO4. The order of reaction in oxidant is unity while that in Substrate and alkali has been found to decrease from unity at higher [Substrate] and [OH-], respectively. The observed rate constants were in order of k aq > kNaLS > kTx-100 > kCTAB, which has been explained in terms of electrostatic and hydrophobic forces.
