Thermodynamics of mixtures of 1-hydropentadecafluoro-n-heptane + 1:4-dioxan

Abstract

Vapour pressures at 36, 40 and 50°C, heats of mixing at 35, 40, 45°C, volumes of mixing at 40°C and thermal pressure coefficients at 40°C are reported for the system 1-hydropentadecafluoro-n-heptane + 1:4 dioxan. The thermodynamic data derived from these measurements are compared with two models for the mixing of liquids in which specific interactions are significant.
