Abstract

The static and dynamical properties of sodium-2- ethylhexyl-phosphate/water/benzene inverted micelles have been investigated using several techniques. Proton NMR, densimetry as well as light and neutron scattering experiments yield a mean aggregation number of 12 ± 1 for a cmc of 8x10-3 M. The domain of stability of these micelles corresponds to water/surfactant ratios W ≤ 6. Above W = 3.5, the release of free water molecules and sodium ions in the miceliar core is evidenced by electrical conductivity measurements.. The anisotropic motions of water and surfactant molecules have been investigated by multinuclear relaxation experiments. The reorientation of water seems consistent with the lone pair model of binding to sodium ions.
