Isobaric Vapor–Liquid Equilibrium Data of Binary Systems Containing 2-Ethoxyethanol, 2-Ethoxyethyl Acetate, and Toluene

“…The NRTL model parameters were optimized by fitting to the experimental VLE data and can be found in Table . The gas composition computed from the model deviates significantly from the experimental data of Gorlova et al The cause of this deviation is either due to a very nonideal gas phase behavior or the inaccuracy of experimental data. This issue cannot be resolved here since the gas phase composition was not measured.…”

“…Comparison of the VLE for the binary system 2-ethoxyethanol (1) + toluene (2) at 101.3 kPa measured in this work (circles) and Gorlova et al (squares). Closed and open symbols are liquid and gas phase data, respectively.…”

“…As shown in Table , our data for the system 2-ethoxyethanol + toluene pass the Redlich–Kister and Wisniak tests. The data of Gorlova et al fails the Redlich–Kister test very badly with D = 100. It is clear that the gas phase data of Gorlova et al should be treated with caution until substantiated further.…”

“…The data of Gorlova et al fails the Redlich–Kister test very badly with D = 100. It is clear that the gas phase data of Gorlova et al should be treated with caution until substantiated further. In Figure , VLE data of the 2-ethoxyethanol + toluene system at all measured pressures is plotted together with the NRTL modeling results.…”

“…This study extends the work of Rana et al, who measured the VLE of the binary system 2-ethoxyethanol + 2-ethoxyethyl acetate. The system 2-ethoxyethanol + toluene has been studied by Naumann and Wagner at 330.15 K at pressures between 4.83 and 16.46 kPa and by Gorlova et al at atmospheric pressure. To the best of our knowledge, the binary system 2-ethoxyethyl acetate + toluene has not been studied previously.…”
