CioH22+w-C4Fio，378K。C2H6+C2F6体系的临界溶点被熔化曲线所掩盖，但估计为157K。这些结果包含和扩展了早期关于烃+氟碳体系的工作。对于所有体系来说，与溶解度参数理论预测值的异常大的偏差是大致相同的，并且与碳氢化合物和氟碳化合物之间的摩尔体积(或碳原子数)的差异没有明显的依赖关系。所有的临界溶液温度都落在一个简单的网格上，该网格允许内插和(谨慎地)外推。临界组成明显依赖于摩尔体积的不同，并支持规则溶液理论的体积分数或表面分数公式。
CioH22+ w-C4Fio, 378 K. The critical solution point for the system C2H6+ C2F6 is hidden by the melting curve, but is estimatedto be 157 K. These resultscontain and extend earlier work on hydrocarbon+ fluorocarbon systems. The anomalously large deviations from the predictions of solubility parameter theory are about the same for all systems, and show no significant dependence uponthe differences in molar volume (or number of car-bon atoms) between hydrocarbon and fluorocarbon. All of the critical solution temperatures fall on a simple grid which permits interpolation and (with caution) extrapolation. The critical composition shows a striking dependence upon the difference in molar volume and gives support to a volume-fraction or surface-fraction formulation of regular solution theory.
