Abstract

The total vapor pressure of liquid mixtures of (xenon + n-butane) has been measured at 182.34 and 195.49 K, and of (xenon + isobutane) at 195.49 K. The liquid molar volumes have also been measured at 182.34 K for both systems. The mixtures follow the behavior already found for other (xenon + alkane) mixtures, i.e., negative deviations from Raoult's law, negative excess molar Gibbs energies (G_m^E) and negative excess molar volumes (V_m^E) . The excess molar enthalpy (H_m^E) is approximately zero in the case of (xenon + n-butane) . The results were interpreted using the statistical association fluid theory for potentials of variable attractive range (SAFT-VR) . This study provides further evidence that the (xenon + n-alkane) mixtures can be thought of as a particular case of mixtures of n-alkanes.
