Abstract

Abstract: The isothermal phase diagram for the system cetylpyridinium bromide/n-butanol/n-octane/H₂O has been determined at 40℃,The ²HNMR spectroscopy and DSC methods have been used in deterimining the structures. The results showed that the liquid crystal phase constructures not only changed with variation of the content of water at a certain temperature, but also changed with variation of temperature at a certain composition.

Key words: CPDB, Lyotropic liquid crystal, ²HNMR, DSC
