Vapor−Liquid Equilibrium of Two Aqueous Systems that Exhibit Liquid−Liquid Phase Separation

Vapor−Liquid Equilibrium of Two Aqueous Systems that Exhibit Liquid−Liquid Phase Separation

Accurate vapor−liquid equilibrium (VLE) data have been measured for the systems 2-butanol + water at 318.19 K, 338.37 K, and 353.45 K and for 2-butoxyethanol + water at 363.18 K and 371.19 K. The VLE measurements were done with a Stage−Muller dynamic still. The binary data reported satisfy thermodyn...

Zusammenfassung:Accurate vapor−liquid equilibrium (VLE) data have been measured for the systems 2-butanol + water at 318.19 K, 338.37 K, and 353.45 K and for 2-butoxyethanol + water at 363.18 K and 371.19 K. The VLE measurements were done with a Stage−Muller dynamic still. The binary data reported satisfy thermodynamic consistency tests. In addition, the liquid−liquid equilibria for the system 2-butoxyethanol + water have also been measured at these temperatures.
