Abstract
The binary phase equil. for the system Na taurodeoxycholate-H2O were studied. The system forms a liq. cryst. phase in addn. to the previously known isotropic soln. phase at 22°. 2H (water) NMR quadrupole splitting, SAXS data in combination with the polarizing microscopic texture obsd. for the liq. crystal indicate that the liq. cryst. phase consists of a hexagonal-type aggregate structure. A metastable liq. crystal, probably with lamellar-type structure, also appears to exist prior to the formation of the stable hexagonal phase. A micellar growth is measured with the NMR self-diffusion method for the isotropic soln. phase. Elec. conductance expts. were used to det. the liq. crystal-soln. thermal transition.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
