ABSTRACT
Some physicochemical properties such as dissociation constant, acoustical parameters and
thermal studies of acid are studied in methanol and 1,4-dioxane at 298.15 K. The dissociation constant
of Chenodeoxycholic acid is evaluated in binary mixtures (of methanol / 1,4-dioxane + water) by two
methods; half-integral and average methods. The acoustical properties have been evaluated from
experimental data of density, viscosity and ultrasonic velocity. It is observed that in both the solvents,
strong solute-solvent interactions exist. Thermal degradation of Chenodeoxycholic acid is found to be
a single step process.
