Temperature dependence of emulsion morphologies and the dispersion morphology diagram for three-phase emulsions
- Morgantown Energy Technology Center, WV (United States)
Using several different compositions of the (pseudo)ternary amphiphile/oil/{open_quotes}water{close_quotes} system C{sub 6}H{sub 13}(OC{sub 2}H{sub 4}){sub 2}OH/n-tetradecane/aqueous 10 mM NaCl that form oil-rich top phases (J), water-rich bottom phases ({Beta}), and middle-phase microemulsions (m), we showed by means of electrical conductivity measurements that the temperature dependencies of the three-phase emulsion morphologies were consistent with predictions from isothermal dispersion morphology diagrams, thus contradicting ideas derived from the PIT (phase inversion temperature) model for two-phase emulsions. In particular, we formed three-phase emulsions in which either (1) the continuous phase was an oil-rich phase (actually, m) below the PIT and the water-rich phase ({Beta}) above that temperature; (2) the water-rich phase was continuous both below and above the PIT; or (3) oil-rich phase was the continuous phase both below and above the PIT.
