NITROGEN SOLUBILITY AND VAPOR PRESSURE OF BINARY MIXED SOLVENTS CONTAINING BENZENE, CARBON TETRACHLORIDE, CYCLOHEXANE AND 1-HEXANE

摘要

References(25) Cited-By(3) Experimental data are presented for vapor pressure and nitrogen solubility at 25 °C for three binary nonpolar mixtures: cyclohexane + 1-hexane, cyclohexane + carbon tetrachloride and benzene + carbon tetrachloride. The one-fluid van der Waals model with the Carnahan-Starling equation for a reference fluid expression is applied to represent three thermodynamic excess quantities: the excess Gibbs energy, the excess molar volume and the excess quantity of gas solubility. It is found that agreement of the theory and the experiments is fairly good for mixtures of relatively globular molecules of benzene, cyclohexane and carbon tetrachloride. However, disagreement is found for mixtures of cyclohexane + 1-hexane.
