Abstract
The effect was investigated of increasing concentrations of co-solvents ethanol, isopropanol, tetrahydrofuran (THF), dimethylformamide (DMF), formamide and ethylene glycol on the selectivity of inclusion for binary mixtures of the following guest molecules: pinene, eugenol, cineole, limonene and camphor, and of isopropanol for the ternary mixtures eugenol/cineole/pinene; and limonene/cineole/pinene. In contrast to the strong solvent dependent effects onβ-cyclodextrin solubility, the changes in selectivity are similar for each system, show little variation from solvent to solvent and are guest dependent. Similar guest induced effects are observed for ternary mixtures. They appear to be additive.
