Description:
Winsor Type I (o/w), Type II (w/o), and Type III (middle phase) microemulsions have been generated for water and perchloroethylene (PCE) in combination with anionic surfactants and the appropriate electrolyte concentration. The surfactant formulation was a combination of sodium dihexyl sulfosuccinate and sulfated Guerbet alcohol ethoxylates and propoxylates. All studies were done at 25 °C and the experimental data presented are electrolyte concentration and solubilization parameter for optimum formulations and width of the three phase regime in salinity space. Many of the results are reminiscent of those obtained with hydrocarbons for the oil phase once it is realized that PCE requires more hydrophilic surfactants than does octane.
