“…Mixed xylene without separation also finds application as gasoline additives. 4 Various separation processes are usually optimized using process simulators. Performance of simulators is dependent on the prediction accuracy of fluid thermodynamic properties at different conditions in the process that in turn depends on the thermodynamic model that takes into account nonideal behavior of the system.…”

Isobaric binary vapor–liquid equilibrium (VLE) data for dimethyl carbonate with xylene isomers (p-xylene, m-xylene, o-xylene, and ethylbenzene) were measured at the local atmospheric pressure of 93.13 kPa by using a dynamic recirculation still. The experimental VLE data were tested and found to be thermodynamically consistent by Herington and Van Ness consistency test. The experimental VLE data were correlated using the Wilson, NRTL, and UNIQUAC activity coefficient models and binary interactions parameters were estimated using a suitable objective function. The absolute mean deviation between the experimental and the model predicted values of vapor phase composition and total pressure was well within acceptable limits. No azeotrope was observed in any of the binary pairs and appeared to be easy for separation using conventional distillation method.

The fundamental component of the data used in chemical calculations is vapor−liquid equilibrium (VLE) information. The VLE data between several routinely used extractants and chemicals often utilized in industry still have some gaps, nevertheless. The isobaric phase equilibrium values of ethyl acetate + 1-hexanol, methanol + 1-hexanol, and n-heptane + cyclohexanol at 101.3 kPa were measured by using a modified Rose VLE still. The accuracy of experimental data was verified using two test techniques, the Van Ness and Fredenslund tests, and the final experimental data were highly correlated. The NRTL model, UNIQUAC model, and WILSON model were used to correlate the data, and binary interaction parameters between the components were derived. The three systems all meet the data requirements with respect to the root-mean-square deviation (RMSD) and average absolute deviation (AAD) of temperature being less than 0.1 and the RMSD and AAD of the vapor phase mole fraction being less than 0.01. The experimental and predicted values of all data points are in good agreement, and they all meet the requirements outlined in the process design. Additionally, it is discovered that the system under study behaves optimally throughout the whole research domain.
