Abstract
Binary vapor-liquid equilibrium data for the systems, MeOH-EtAc, EtAc-EtOH, EtAc-n-PrOH and EtAc-n-BuOH, were measured under atmospheric pressure using methods developed for MeAc-Alcohol systems presented in a previous report.
The measured x-y data were discussed to be correct or not, by means of Herington's consistency test, and the relationships between the liquid composition and Q-function or activity coefficient.
Van Laar's constants A, B were determined experimentally and compared with previously published values.
The author determined the constants for Prahl's equation using the experimental data, corrected the azeotropic composition of MeOH-EtAc system, also suggested density-composition relation at 20 ℃, and obtained the somoothed data of vapor-liquid equilibria at the atmospheric pressure for the EtAc-Alcohol systems.
