| Abstract: | The solubility of eight calix4]arenes and crown-calix4]arenes in n-hexane at five different temperatures was determined by isothermal saturation. The thermodynamic dissolution parameters were
calculated. Thermodynamics of solvation in n-hexane was calculated using thermodynamic parameters of sublimation obtained earlier. Thermogravimetric analysis of the bottom
phase was carried out to detect crystallosolvates. The stoichiometry of the crystallosolvates formed was ascertained. |
