Carbonate esters and esters are widely used in the pharmaceutical industry. It is important to enrich the vapor−liquid equilibrium (VLE) database of these components. In this article, the isobaric VLE data of three binary mixtures diethyl carbonate (DEC) + methyl acetate, DEC + n-propyl acetate, and DEC + amyl acetate at 100.17 kPa were obtained. The experimental data were tested using the Van Ness consistency test, which indicated that the experimental data satisfy the test for thermodynamic consistency. The activity coefficient models Wilson, NRTL, and UNIQUAC were used to correlate the experimental VLE values to obtain the interaction parameters. The results associated with the three models are in good agreement with the experimental data. The minimum average absolute deviation values of vapor-phase compositions and temperatures for all are 0.0010 and 0.15 K, and no azeotropic behavior was observed in these systems. In addition, the group contribution method was used to fit the group parameters of the vapor−liquid equilibrium data.

“…The VLE experimental data for the binary systems isopropyl acetate + DEC, sec-butyl acetate + DEC, and DEC + isoamyl acetate were correlated with the Wilson, NRTL, and UNIQUAC activity coefficient models. Among them, the nonrandom parameter (α 12 ) of the NRTL model was determined to be 0.3 according to the recommendations of Renon and Prausnitz et al 23,40 Meanwhile, when the experimental data are associated with the activity coefficient model and UNIFAC-DMD model, the objective function of the regression is the maximum likelihood function. The maximum likelihood function is represented in eq 6. coefficient model are listed in Table 8, In addition, the groups of these three binary systems are CH 3 -, CH 2 -, CH-, -OCOO-, and -COO-.…”

Carbonate esters and esters were commonly used as solvents, reaction carrier, and additives in organic synthesis, the pharmaceutical industry, and processing industries. Vapor–liquid equilibrium (VLE) data are vital to the separation process or process simulation for separating solvents. Therefore, it is necessary to enrich a VLE database for carbonate esters and esters. In this study, isobaric VLE data for three systems of isopropyl acetate + diethyl carbonate (DEC), sec-butyl acetate + DEC, and DEC + isoamyl acetate at 101.3 kPa were determined for enriching the group interaction parameters for carbonate esters. Meanwhile, the thermodynamic consistencies of the VLE data were tested using the Van Ness method modified by Fredenslund et al. The Wilson, NRTL, and UNIQUAC models were used and found to have good consistency for all binary systems between the experimental and simulated data. At the same time, the VLE data were correlated by the UNIFAC-DMD model to supplement the group parameters for carbonate esters. The average absolute deviation (AAD) of the temperature of the activity coefficient model and the UNIFAC-DMD model is not less than 0.16 K, and the AAD of the vapor phase mole fraction is not less than 0.0016. In addition, azeotropy did not occur in all binary systems.

Isobaric Vapor–Liquid Equilibrium for the Binary Systems of Diethyl Carbonate with Xylene Isomers and Ethylbenzene at 101.33 kPa

Isobaric binary vapor−liquid equilibrium (VLE) data for diethyl carbonate with ethylbenzene and xylene isomers are measured at 101.33 kPa by using a modified Rose still. The binary VLE data are tested to be thermodynamically consistent by the Herington method and the point-to-point test of the Fredenslund method. Taking account of the nonideality of the vapor phase, the activity coefficients of the components are calculated. All systems present a positive deviation from ideality. The experimental VLE data are well correlated by the nonrandom two-liquid (NRTL), universal quasichemical activity coefficient (UNIQUAC), and Wilson equations. The calculated vapor-phase compositions and temperature agree well with the experimental values. These experimental data can provide basic thermodynamic data for practical application in developing the distillation simulation of diethyl carbonate with ethylbenzene and xylene isomers.
