“…NIST-COSMO-SAC describes the experimental data somewhat better at x1 > 0.8 than NIST-modified UNIFAC though the consistency trends are similar. The predicted pressures and gas-phase compositions are in good agreement with the experimental data for (2-methylfuran + butanone) [54]. The deviations close to -20 % are observed for (2,5dimethylfuran + 4-methylpentan-2-one) [45] at the pressures close to 10 kPa.…”

The experimental vapor-liquid equilibrium (VLE) data for the binaries relevant to the catalytic fast pyrolysis of biomass have been collected and analyzed using the NIST-COSMO-SAC and NIST-modified UNIFAC models. The existing inconsistencies in the experimental data and the predicted values are discussed. For VLE with furan derivatives, PTxy data are normally reported, and the predicted values are in good agreement with them. For phenolic compounds, the gas phase compositions are available for only 36 % of the points, most results originate from a few laboratories, and each system has been typically studied in a single laboratory. The binaries are identified where more experimental VLE data are required to evaluate quality of the existing experimental and predicted results.

“…Results show a solubility minimum at approximately 313 K and x (2-methylfuran) = 0.0007. Only one solubility point was found in the literature for the measured system, it is at 298.15 K (Smith and LaBonte). The Henry’s law constants for 2-methylfuran in water are presented in Wieland et al The solubility values calculated from the results of Wieland et al agree with the measurements presented in this work at 323.15 and 298.15 K. These values are in agreement, within experimental uncertainties, with this work and that from Smith and LaBonte’s (1952) .…”

“…The interaction parameters in Tables 8 and 9 of the activity coefficient models were regressed against experimental LLE from this work and VLLE data. 25 The ability of our regression using these two activity coefficient models to describe the measurements were examined with two scenarios. In case 1 four parameters of each model (NRTL and UNIQUAC) were regressed while in case 2 six parameters were regressed.…”

Acquiring accurate experimental thermodynamic data is very useful for the development of models and chemical processes. Although there are plenty of data in the scientific literature, there are still many missing. In fact, many of the easier measurements have been made, and far more of the remaining ones deal with either complex systems or extreme conditions. Clearly new adequate equipment for acquiring such data are welcome. For these purposes, advice coming from several decades of equipment design experience are exposed herein. After defining the aim pursued and consequently the type of desired thermodynamic quantity, it is necessary to take into account all physical and chemical constraints: viscosity, density, corrosive power of studied chemical systems, temperature, pressure together with other important points such as miniaturization, efficient stirring, avoiding both dead volume and polymer sealing. The other aim of this paper is to present a high temperature and high pressure apparatus capable of measuring the phase equilibria of systems exhibiting vapor–liquid–liquid behavior. The apparatus designed and built consists mainly of an equilibrium cell (70 cm3), novel high temperature, and high pressure samplers and a gas chromatograph. A detailed description of the apparatus is presented. Preliminary measurements are presented for propane in water, cyclohexane in water, and water in cyclohexane up to 498.8 K. In addition the solubility of 2-methylfuran in water up to 413 K and 1548 kPa was measured.
