“…doi:10.1016/j.fluid.2011.09.035 reaction had been also considered in [23], but this work does not give a complete thermodynamics description, only binary systems ethanol-acetic acid and ethyl acetate-water were investigated (50 kPa and 101.3 kPa). Authors of [24] measured the chemical equilibrium constant (348-373 K), the experimental data on vapor-liquid equilibria were correlated using UNIQUAC model, calculations were found to be in a good agreement with the experimental data (343 K, 101.3 kPa). Another research of vapor-liquid equilibria (519-559 K, 101.3 kPa) is presented in [25].…”

a b s t r a c t Solubility, critical states and liquid-liquid equilibrium (LLE) data for the quaternary system acetic acid-ethanol-ethyl acetate-water and for the ternary sub-systems acetic acid-ethyl acetate-water and ethanol-ethyl acetate-water were obtained at 293.15 K and atmospheric pressure. Binodal curves, tielines and compositions of critical points were determined. In order to construct the binodal surface and critical curve of the quaternary system, three quaternary sectional planes with several ratios of acetic acid and ethanol were studied. Experimental LLE data were compared with the values calculated by UNIFAC model and it was found that the experimental and calculated data are in a good agreement.

a b s t r a c tSolubility, critical states and liquid-liquid equilibrium (LLE) data for the quaternary system acetic acid-ethanol-ethyl acetate-water and for the ternary subsystems acetic acid-ethyl acetate-water and ethanol-ethyl acetate-water were studied at 303.15 K and 313.15 K and atmospheric pressure. Binodal surfaces, binodal curves, tie-lines and compositions of critical points were determined. In order to construct the binodal surfaces and critical curves of the quaternary system, five quaternary sectional planes with several different ratios of concentration of acetic acid to ethanol were studied. Experimental LLE data were compared with the values calculated by UNIFAC and NRTL models, and it was found that the experimental and calculated data are in good agreement.

“…To correlate their experimental data, they used UNIQUAC and Wilson with consideration of the association of acetic acid in the vapor phase using Hayden-O'Connell (1975) second virial coefficients. The optimization technique applied to determine the model parameters was similar to Kang et al (1992) procedure and used the quaternary data.…”

-A correlation procedure for the prediction of vapor -liquid equilibrium of acetic acid -isopropanol -water -isopropyl acetate mixtures has been developed. It is based on the NRTL model for predicting liquid activity coefficients, and on the Hayden-O'Connell second virial coefficients for predicting the vapor phase of systems containing association components. When compared with experimental data the correlation shows a good agreement for binary and ternary data. The correlation also shows good prediction for reactive quaternary data.
