Isobaric Vapor-Liquid Equilibrium for Binary Systems of Allyl Alcohol with Water, Methanol, and Ethanol at 101.3 kPa

Isobaric vapor-liquid equilibrium (VLE) data for three binary systems of (allyl alcohol + water), (allyl alcohol + methanol), and (allyl alcohol + ethanol) were measured at atmospheric pressure of 101.3 kPa by a modified Rose vapor recirculating type equilibrium still. The thermodynamic consistency test for the experimental data of the three binary systems containing allyl alcohol were checked by Herington method and van Ness test, respectively. Meanwhile, the measured VLE data were correlated by three activity coefficient models of Wilson, nonrandom two-liquid (NRTL), and universal quasichemical (UNIQUAC), for which all of the calculated results showed good consistency. The binary interaction parameters of the models were also regressed. The azeotropic behavior could not be observed in (allyl alcohol + methanol) and (allyl alcohol + ethanol) systems, but for (allyl alcohol + water) system, the azeotropic behavior was found, and it had the minimum azeotropic point.
