The viscosity of the mixture of water / 2,6-dimethylpyridine / NaBPh4 at lamellar phase and disordered phase

We have observed transitions from lamellar to isotropic phase of a mixture solution which are composed of pure water, 2,6-dimethylpiridine and an antagonistic salt, NaBPh₄, using a polarization microscope. The experimental results have indicated that the phase transitions depend on the concentration of NaBPh₄ and temperature. The NaBPh₄ take a decisive role for the stability of the mixture solution.
