Abstract

Electrical conductivity of water/sodium dodecyl sulfate/l-butanol/oil microemulsions having molar ratios of water to surfactant and surfactant to cosurfactant equal to 44 and 0.1144 respectively, was measured at 25°C using eight different oils (octane, benzene, toluene, carbon tetrachloride, chloroform, cyclohexane, m-xylene and nitrobenzene). These microemulsions have been found to fall in the w/o and bicontinuous regions over the range of volume fractions of oils covered in this study. The specific conductivity data were least-squares fitted to a virial expression. In the w/o region the dimensional characteristics of the microemulsions were estimated.
