The effect of benzyl alcohol on the rheology and H-1 NMR spectra of CTAB of CTAB/KBr micellar system

The influence of benzyl alcohol on the rheology and H-1 NMR spectra of CTAB of CTAB/KBr micellar system has been investigated. The addition of benzyl alcohol induces the viscosity of 0.01 mol/L CTAB/KBr micellar system to go through a marked maximum, In terms of H-1 NMR spectra of CTAB, it is argued that a little amount of alcohol solubilized in the interfacial region of C TAB/KBr micelles will promote these micelles to be longer and overlapping. This process makes the viscosity of the system rise, With increasing alcoho l concentration continuously, it will be dissolved in the palisades of mice lles and induces the rod-like micelles to be transformed into small sphere ones and disentanglement, Then the viscosity of this micellar system decrea ses.
