“…Figure depicts the application of a visual and variable-volume PEA for the purpose of empirically ascertaining the VLE phase boundaries of CO 2 + eugenol and CO 2 + guaiacol with a specific focus on the near critical regions. Previous studies have described the PEA illustration. − The PEA is composed of two syringe pumps, a high-pressure cell with changeable volume and visual display, a magnetic stirrer, a digital camera fitted with light sources, an LCD monitor, a rupture disk, and a vacuum pump. The high-pressure cell underwent modification through the utilization of a pressure generator, specifically the model 62-6-10 manufactured by High-Pressure Equipment Co. located in Erie, USA.…”

The vapor–liquid equilibrium (VLE) phase boundary data for the binary systems consisting of carbon dioxide + eugenol and carbon dioxide + guaiacol were determined experimentally in the temperature range from 313.15 to 373.15 K and at pressures up to 24 MPa. The phase transition over the entire composition range was observed by using a variable-volume and visual phase equilibrium analyzer. From the VLE phase boundary data, K-values and critical points for VLE have been estimated. The present study involved the correlation of the recently obtained VLE data with two equations of state, namely, the Soave–Redlich–Kwong and the Peng–Robinson equations. These equations were modified to incorporate the two-parameter van der Waals one-fluid mixing rule. Overall, the average absolute pressure deviations are lower than 3%.

“…Thus, electrolyte PC-SAFT (ePC-SAFT) advanced was developed, which contains a modified Born term to account for the concentration-dependent dielectric-induced solvation of the ions . This model shows predictive capabilities concerning CO 2 solubility. − Moreover, ePC-SAFT advanced was also successfully applied in previous works to model solid–liquid equilibria (SLE) of electrolytes in organic solvents, cf., Pabsch et al , In the literature, several works experimentally investigated the CO 2 solubility in organic solvents, such as alcohols, acids, and esters. − However, the CO 2 solubility in solvent mixtures containing electrolytes is scarcely reported in the literature.…”

The influence of solvents and salts on the CO 2 solubility and the impact on esterification reaction kinetics and equilibrium are of particular interest, e.g., for the esterification of acetic acid with ethanol under the influence of CO 2 , N-methyl-2pyrrolidone (NMP), or electrolytes. In this work, the equation of state (EOS) electrolyte Perturbed-Chain Statistical Associating Fluid Theory (ePC-SAFT advanced) was first applied to predict the CO 2 solubility in solvent mixtures containing NMP and water with additional electrolytes (NaCl, CsCl). New experimental data on the CO 2 solubility in electrolyte solutions were measured by two different static synthetic methods, and the ePC-SAFT predictions matched well with the experimental data. As a result, NMP increased the CO 2 solubility, compared to water as the only solvent, while electrolytes caused a salting-out effect on the CO 2 solubility in all investigated systems. Further, the kinetics and equilibria of the esterification reaction were studied in the presence of CO 2 , NMP, and electrolytes. New data were measured by using a high-pressure autoclave with in situ ATR-FTIR spectroscopy, which enabled real-time monitoring of the kinetic profiles. Therein, CO 2 and NMP showed a negative effect on the kinetics. However, the additional CO 2 in the reaction mixture positively influenced the equilibrium, while NMP had a negative influence. Finally, ePC-SAFT advanced was applied to predict the influence of CO 2 and NMP on both kinetics and equilibrium of ethanol esterification using a thermodynamic activity-based kinetic approach. Therein, the experimental findings were successfully predicted by the model without fitting any model parameter to the experimental data. Ultimately, this approach reduces the experimental effort toward screening most suitable reaction conditions for chemical reactions and screening the influence of other compounds on kinetics and equilibria.
