Dielectric Properties of Water-Oil System Solubilized with Aerosol OT

With a view to elucidating the dielectric characteristics, of a solubilized system which is different in blending state from both molecular solutions and emulsions, the dielectric constant and the electrical conductivity of solubilized systems of water in kerosine with Aerosol OT were measured over the frequency range of 20 Hz to 5 MHz and the temperature range of 5 to 60°C. The dielectric constant of the solubilized systems examined showed a remarkable dielectric dispersion at frequencies above 100 kHz. At lower frequencies below 30 kHz, the dielectric constant and the conductivity were independent of frequencies, and were different from values expected from theories and experimental information of molecular solutions and emulsions. These limiting values at lower frequencies showed changes in the temperature dependence at 5: 1, 30: 1 and 56: 1 by mole ratio of water to Aerosol OT regardless of the amount of kerosine
