On the liquid mixtures of xenon, alkanes and perfluorinated compounds

Clare McCabe, Lino M. B. Dias, George Jackson and Eduardo J. M. Filipe


The fluid phase behaviour of binary mixtures of xenon and the lighter perfluoro-n-alkanes, CF4 and C2F6, and of propane and sulfur hexafluoride (SF6) has been examined using the statistical associating fluid theory for potentials of variable attractive range (SAFT-VR). We found that the binary interaction parameters calculated in previous work for (n-alkane + perfluoro-n-alkane) systems and for (Xe + SF6), can be used to predict the existing phase diagrams of (Xe + perfluoro-n-alkane) and (propane + SF6) mixtures, respectively. These results are consistent with the view that mixtures of (xenon + perfluorinated-compound) can be regarded as a special case of mixtures of (n-alkane + perfluorinated-compound) and provide another example of the alkane-like behaviour of xenon previously reported.
