Isothermal vapour-liquid equilibrium data for binary systems of (CHF3 or C2F6) with (1-hexene or 3-methylpentane)

The method of Ungerer et al. was used to extrapolate the subcritical co-existence data to the mixture critical loci, while the method of Heidemann and Khalil was used to estimate the critical locus curves for the systems. Each of the four systems were also categorised according to the classification system of van Konynenburg and Scott.
