Studies on the phase diagram of the surfactant/1-pentanol/water ternary system. I: The isotropic phases

摘要

The phase diagram of the dodecyl dimethyl ammonium hydroxyl propyl sulfonate(DDAHPS)/1-pentanol(C_5H_11OH)/wate r ternary system has been established. It contains two isotropic monophase regions(L_1 and L_2) and a liquid crystalline region (L.C.). The isotropic phase regions have been investigated by means of Raman spectroscopy and conductivity.
