Studies on the Pseudo-ternary-component Phase Diagrams of CTAB/ n-Butanol-n-octane-water or Brine Systems and Electrical Conduction of Its Microemulsion Microstructure

Abstract

Abstract: The phase diagrams of the pseudo-ternary-component of CTAB/n-butanol-n-octane-water or brine[Al（NO₃）₃ or Na₂WO₄] systems were studied by dilution method. The microstructures of microemulsions were determined through conductance technique. Via percolation theory and electrolyte theory the single-phase regions of the microemulsions were delimited as W/O,O/W and bicontinuous microemulsion domains. In the W/O microemulsion regions we got a small domains（L′） in which the dispersed entities are of spherical form.

Key words: CTAB, Microemulsion, Pseudo-ternary-component phase diagram, Conductivity
