Thermodynamics of mixtures with strong negative deviations from Raoult’s law. XVIII: Excess molar enthalpies for the (1-alkanol + cyclohexylamine) systems at 298.15 K and modelling

The density of five 1-alcohols (1-hexanol, 1heptanol, 1-octanol, 1-nonanol, and 1-decanol) was measured using a vibrating-tube densimeter at pressures of up to 120 MPa for temperatures between 298.15 and 423.15 K. The relative expanded uncertainty of the experimental data is below 0.2%. The new results significantly extend the available literature data. The density of the five alcohols was modeled using four molecular-based equations of state (EOSs), namely PC-SAFT, SAFT-VR Mie, soft SAFT, and CPA. New component-specific EOS models were parametrized for all considered EOSs and substances using vapor−liquid equilibrium data from the literature and the density data from this work. The resulting EOS models describe the density with deviations of about 0.2−1.5%. For the thermal second-order derivative properties, the relative deviations were 10−50% for the isothermal compressibility and 5−35% for the thermal expansion coefficient. Also, the extrapolation behavior of the EOS models was assessed. Overall, the best results were obtained from the SAFT-VR Mie EOS.
