Abstract

Isothermal vapor-liquid equilibrium (VLE) data for two binary mixtures of ethanol + glycerol and 2-propanol + glycerol were determined at the temperature range from (323.15 to 343.15) K using a simple quasistatic ebulliometer. The experimental data were correlated with the Wilson, nonrandom two-liquid (NRTL), and universal quasichemical (UNIQUAC) activity coefficient models. Both systems show that the vapor pressures increase with increasing alcohols concentrations, and no azeotropic behaviors are exhibited. In addition, both systems show positive deviations from the Raoults Law.
