Isothermal vapour-liquid equilibria of mixtures of organic compounds. Part 8. Excess Gibbs energies of tetrachloromethane + cyclic oxaalkane mixtures at 298.15 K

Vapour-liquid equilibria for tetrachloromethane + a cyclic mono or polyoxaalkane (oxetane, oxane, oxepane, 1,3-dioxolane, 1,3-dioxane, 1,3-dioxepane, 1,3,5-trioxane), were determined at 298.15 K by head-space gas chromatographie analysis of the vapour phase directly withdrawn from an equilibration apparatus. Excess Gibbs energies, activity coefficients at infinite dilution, and Gibbs energies of solvation were calculated and briefly discussed for all the systems.
