Ternary phase behavior of water + propanoic acid + 3-methylbutyl acetate and water + propanoic acid + propan-2-yl acetate ternary mixtures including solubility and tie-line data was defined at (298.15 to 318.15) K under the pressure of 83.4 ± 1 kPa. The compositions of tie-line and bimodal curves were obtained by refractive index measurements. The phase diagrams show the type-1 behavior of liquid−liquid equilibrium (LLE). The capability of the solvents for the extraction of propanoic acid from aqueous solutions was determined by distribution coefficients and separation factors. The reliability of the experimental tie-line data was ascertained by Othmer−Tobias and Hand correlation equations. The tie-line data were correlated with nonrandom two-liquid (NRTL) and universal quasi-chemical (UNIQUAC) models. The binary interaction parameters of the models were reported. Excellent agreement was observed between the experimental data and the correlated values.

“…The phase behavior of binary and multicomponent mixtures of 2,2-dimethyl-1,3-dioxolane-4-methanol (DMDM) with n-heptane, ethanol and water was studied in [26]. Experiments have shown the complete mutual miscibility of the components in DMDM + water and DMDM + ethanol mixtures in the temperature range 243.15-313.15 K, whereas for DMDM + n-heptane mixtures a miscibility gap was observed.…”

“…The ability to correlate VLLE data for binary mixtures of water with 2-methyl-1,3-dioxolane or with 2,4-dimethyl-1,3-dioxolane applying the UNIQUAC model was studied in [25]. The calculations using the UNIFAC model were performed to describe the mutual solubility of the components in binary and multicomponent mixtures of 2,2-dimethyl-1,3-dioxolane-4-methanol with n-heptane, ethanol and water [26]. Nevertheless, further studies are needed to optimize the phase behavior modeling for these complex mixtures which are of applied interest (in particular, in the search of effective additives for biofuels, as it was mentioned above).…”

“…Subsequently, these components have been analyzed with the purpose of making an efficient and adequate selection of a solvent for the separation of azeotropes with methanol, which is why ionic liquids (ILS) have received significant interest in recent years as its application in industrial processes refers [11]. In recent years, new applications have been found for methanol derivatives such as gasoline additives, biofuels, diesel fuels etc., because mixtures of this with other substances have proven to be effective and non-toxic inhibitors of ice formation [12].…”

This paper is related to the procedure for calculating curves dew point and bubble point of a binary system, consisting of the methanol and benzene mixture to 45°C, using the Peng-Robinson cubic equation to calculate the fugacity coefficient of gas i in the mixture, and Van Laar model to calculate the activity coefficient of component i in the liquid mixture. Then a comparison between the theoretical data with the experimental data and later with the commercial simulator Hysys-Aspen, which applies the model of Wilson. The simulation was validated with experimental data,in addition to comparing the results with a commercial simulator.
