| Popis: | In this study, the complexes of β-cyclodextrin with benzoic acid and rutin were obtained in water-ethanol solvents. The yields of both complexes in binary mixtures is greater than in pure water and reached maximum values at range of 0.05–0.10 mole fraction of ethanol. The impact of water–ethanol solvent on thermodynamics of complexation between β-cyclodextrin and benzoic acid was analyzed on the base of solvation–thermodynamic approach as a model of inclusion complex formation reaction. |
