“…In the meantime, an extended GC-correlation study of a,x-alkanediols was published by Chickos et al [13], as well as a very careful vapour pressure measurements were reported from the static method just recently [14]. We also overlooked in reference [4] vapour pressures measured by ebulliometry [15] and by the thermogravimetry [16].…”

The application of the 2C association scheme proposed by De Villiers et al. (Ind. Eng. Chem. Res. 2011 50, 8711−8725) in the association term of cubic plus association equation of state (CPA EoS) is extended to polyol containing systems to correlate the binary and predict the ternary mixtures. First, the CPA parameters of pure components were successfully adjusted by vapor pressure and saturated liquid density experimental data. Then, the performance of the aforementioned scheme is compared to the other classical schemes by modeling the vapor−liquid equilibria (VLE) and liquid−liquid equilibria (LLE) of binary {polyol/small alcohol}, {polyol/ water}, {fatty acid ester/small alcohol}, and {polyol/alkane} and ternary {small alcohol/poyol/fatty acid ester} and {small alcohol/water/poyol} mixtures. Applying a simple and robust phase equilibria algorithm proposed by Privat et al. (Comput.Chem. Eng. 2013, 50, 139−151) to binary and ternary systems, the VLE and LLE correlative performance of CPA EoS coupled with various combined schemes are very satisfactory over extensive temperature ranges and shows that each model is within or close to experimental uncertainty. Then, using two temperature-independent binary interaction parameters (BIPs) fitted with binary VLE and LLE data, the predictive performance of different models is further evaluated in ternary systems phase equilibria (LLE and VLE), and acceptable results are achieved at different temperatures. Eventually, it has been demonstrated that 2C scheme exhibits remarkable precision in predicting the VLE and LLE of polyol containing systems.

“…The apparatus is designed for the measurements of both atmospheric and low pressure VLE. The equipment and procedure were nearly the same as the one used in our previous investigation . It is a recirculation type, in which both liquid and vapor are continuously recirculated, and allows the determination of the equilibrium compositions of both phases.…”

Both vapor pressures and vapor−liquid equilibria (VLE) of the 2,2,2-trifluoroethanol (TFE) + quinoline system, which can be considered as a potential candidate to overcome serious disadvantages of the existing working fluids used for absorption chillers, were measured in order to determine the allowable operation range of this organic mixture. Vapor pressures were measured by using the boiling point method in the temperature range of 293.15 K to 458.55 K and in the concentration range of (0.0 to 100.0) mass percent of TFE and were correlated with an Antoine-type equation. The resulting average absolute deviation (AAD) between the experimental and calculated values was found to be 2.22%. The isobaric VLE data of the 2,2,2-trifluoroethanol (TFE) + quinoline mixture were measured at three different pressures of (13.33, 53.33, and 101.33 kPa), and the thermodynamic consistency was checked by using the point test method.
