Abstract: | Densities and excess volumes were determined at 298.15 K for propyl methanoate + ethanol, +propan-1-ol, and +butan-1-ol. The results of those quantities were then correlated to get the concentrations of vapor-liquid equilibrium obtained isobarically at 160 kPa for the same mixtures. Two mixtures show azeotropes: for propyl methanoate (1) + ethanol (2), x1 = 0.443 at T = 358.7 K; and for propyl methanoate (1) + propan-1-ol (2), x1 = 0.762 at T = 368.2 K. The mixtures are thermodynamically consistent, and the predictions made using several group-contribution models are satisfactory. |
