Abstract / Full Text

Reactions of the inclusion complexation of β- and γ-cyclodextrins (β-CD and γ-CD) with benzoic acid (BA) in water-dimethyl sulfoxide media have been investigated at pH 3.6 and 1.65 and T = 298.15 K using isothermal titration calorimetry and UV-Vis spectroscopy. The standard thermodynamic parameters (lg, ΔrH°, ΔrG°, and TΔrS°) have been estimated for the formation of [BAβ-CD] and [BAγ-CD]. It was found that when H2O-DMSO mixtures were used as the solvent instead of pure water, the stability of complexes slightly decreased.
