Isobaric Vapor–Liquid Equilibrium of Binary Mixtures of Acetophenone and 1-Phenylethanol at 3.00, 5.00, 10.00, and 15.00 kPa

Vapor–liquid equilibrium (VLE) data for the acetophenone (AP) and 1-phenylethanol (1-PE) binary system were measured at 3.00, 5.00, 10.00, and 15.00 kPa by using a modified Rose–Williams distiller. The thermodynamic consistency of the experimental data was verified through the Fredenslund test and Van Ness test. The data were correlated using the NRTL, UNIQUAC, and Wilson models, with root-mean-square deviations (RMSDs) for vapor composition (y1) and equilibrium temperature (T) calculated. The findings suggest that the NRTL, Wilson, and UNIQUAC models are appropriate for use in this system.
