Purity of Aerosol-OT(AOT): Effect on Processes in Reversed Micelles and Water-In-Oil Microemulsions
The presence of impurities in AOT can have very dramatic effects on the kinetics of reactions in microemulsions and to a lesser extent on other properties, e.g. solubilization capacity. If the AOT contains a water-soluble impurity at the 0.1% level (mole per cent), a water-in-oil microemulsion prepared using 10−lmol dm−3 AOT and containing 1% by volume of water will have an impurity concentration in the water phase of 10−2mol dm−3 of water. In a kinetic experiment, this is likely to be in excess of the reactant concentrations. On the other hand, impurities which partition into the oil phase are normally of little consequence.
