Gn. Escobedo-alvarado et Si. Sandler, Vapor-liquid equilibrium of two aqueous systems that exhibit liquid-liquidphase separation, J CHEM EN D, 44(2), 1999, pp. 319-322
Accurate vapor-liquid equilibrium (VLE) data have been measured for the sys
tems 2-butanol + water at 318.19 K, 338.37 K, and 353.45 K and for 2-butoxy
ethanol + water at 363.18 K and 371.19 K. The VLE measurements were done wi
th a Stage-Muller dynamic still. The binary data reported satisfy thermodyn
amic consistency tests. In addition, the liquid-liquid equilibria for the s
ystem 2-butoxyethanol + water have also been measured at these temperatures
