Isobaric Vapor-Liquid Equilibrium Measurements and Calculations Using Nontraditional Models for the Association Systems of Ethyl Acetate+2-Ethylhexanoic Acid and Propyl Acetate+2-Ethylhexanoic Acid at Atmospheric Pressure
In this work, experimental isobaric vapor-liquid equilibrium data were measured for the ethyl acetate (EAC) + 2-ethylhexanoic acid (EA) and propyl acetate (PAC) + EA systems at atmospheric pressure. The experimental data were in good agreement with the NRTL-HOC, UNIQUAC-HOC, and Wilson-HOC models. The maximum absolute deviations and mean absolute deviations of temperature were less than 0.94 and 0.80, respectively. The maximum absolute deviations and mean absolute deviations of the mole fraction of the vapor phase were less than 0.0094 and 0.0067, respectively. The Van Ness method was used to check the thermodynamic consistency of the experimental data. In addition, the binary interaction parameters for the EAC + EA and PAC + EA systems were obtained.
