Cinetique chimique en milieu micellaire. Relation entre vitesse de réaction et structure du milieu

Abstract

A reaction has been studied between two reactants where one, ionic, is dissolved in the aqueous phase and the other, nonionic, is distributed between the aqueous phase and a micellar phase. The kinetic study of this reaction has helped to elucidate the mechanism of the reaction.Depending on the experimental conditions, it is possible to have either an equilibrium of the nonionic solute between the aqueous and micellar phases, or a reaction rate limited by the rate of diffusion of this reactant from the micellar phase to the aqueous phase. It will be shown that such kinetic studies can be used to determine quantitatively the distribution of the solute between the various phases and even inside the micelles. [Journal translation]
