STUDY OF THE PHASE-DIAGRAM OF THE CTAB BENZYL ALCOHOL-WATER SYSTEM

The phase diagram of the ternary system CTAB/benzyl alcohol/water has been studied. The system shows a clear, isotropic and low-viscous regi on, the L phase, and three liquid crystalline mesophases, two of which have been characterized as hexagonal H-1 and lamellar L alpha mesopha ses; the third could correspond to a cubic mesophase. The L phase is s tudied with conductivity and steady state fluorescence quenching measu rements to elucidate the presence of mixed micelles in aqueous solutio n or reverse micelles in alcohol.
