(Liquid+liquid) equilibria for ternary mixtures of (water+propionic acid+organic solvent) at T=303.2K

(Liquid+liquid) equilibria for the ternary (water+acetic acid+toluene) system at different temperatures: Experimental data and correlation

“…The detailed description of the meaning of parameters and equations is expressed in the literature [22]. The values of r and q used in the UNIQUAC model for this system are given in literature [23,24]. The coefficients that were retrieved from the Aspen Plus simulator, based on the above equations to calculate the binary interaction parameters for the NRTL and UNIQUAC models, are listed in table 5.…”

Experimental and Correlated Liquid–Liquid Equilibrium Data for (Water + Propionic Acid + Ethylbenzene or Benzyl Benzoate) Ternary Systems

“…Average values of selectivity ( S ) for the (water + propionic acid + organic solvents) ternary systems at T = 298.2 K (the reported data were taken from the literature). ,,, (The S value for the system containing ethylbenzene corresponds to T = 308.2 K).…”

“…In our previous LLE studies, the equilibrium data for the aqueous solutions of PA with different organic solvents have been reported. − As an extension of the previous work, we report the LLE data for the ternary aqueous mixtures of propionic acid and aromatic solvents at T = (298.2, 308.2, and 318.2) K and p = 0.1 MPa. In this research, benzyl benzoate (BB, Figure b) and ethylbenzene (EB, Figure c) were tested as organic solvents for separation of PA from water.…”

Experimental determination and correlation of tie line data for the system (water+butyric acid+methylcyclohexane) at four temperatures

“…This solvent has already been used as an extractant in the determination of LLE data for the ternary aqueous mixtures of propionic acid [26]. The focus of this study is placed on the phase behavior of LLE for the aqueous mixtures of BA with MCH.…”
