Ultrasonic Studies Of CTAB/Decanol/Water Systems

D.K.Pandey, Devraj Singh, R.R.Yadav, P.K.Yadawa

The ultrasonic velocity and the attenuation in the n-cetyl-N,N,N-trimethylammoniumbromide( CTAB)+decanol+water lyotropic systems have been measured at different physical conditions like temperature, frequency of the wave and concentration of the components in the solution. The critical temperature and the critical concentration of the component were determined 350C and 0.5 wt%of CTAB in the solution respectively for the formation of liquid crystalline phase. The characteristics and peculiarities of specific textures, which were spontaneously formed, have been discussed correlating with the other studies.
