Summary
The phase equlibrium diagram for the ternary system: Aerosol OT / water / iso-octane is established at 25 °C. In this diagram it is noticed that the reversed micellar solution or microemulsion phase extends in its area so far as the water content reaches 50–60 (wt.%) at which liquid crystalline phase begins to appear. On the experimental data of electric conductivity, viscosity, optical birefringence, etc. for the samples containing a definite amount of AOT (0.28 M), and various relative amounts of water and iso-octane, the mechanism of the transition of reversed micellar structures into lamellar liquid crystalline structures is discussed from the viewpoint of thermodynamics and molecular kinetic theories.
Zusammenfassung
Das Phasendiagramm vom ternären System: Aerosol OT / Wasser / Iso-octan bei 25 °C ist angegeben. In diesem Diagramm ist zu bemerken, daß die Phase der inversen mizellaren Lösung oder Mikroemulsion so weit entwickelt ist, daß ihr Wassergehalt 50–60 (gew.%) erreicht, wobei flüssige Kristalle erscheinen. Auf Grund der experimentellen Daten der elektrischen Leitfähigkeit, Viskosität, optischen Doppelbrechung usw., von den Proben mit dem bestimmten AOT-Gehalt (0,28M) wird der Mechanismus der Umwandlung von inversen mizellaren Strukturen zu lamellaren flüssigen Kristallen aus dem Gesichtspunkt der Thermodynamik und molekularkinetischen Theorie diskutiert.
