Liquid-Liquid Equilibrium of the Ternary System Water/Formic Acid/1-Pentanol at T= 308.2 K

Liquid–liquid equilibrium data for the (water + Formic acid + 1-pentanol) ternary system were determined at T = (308.2) K in ambient pressure. This ternary system exhibits type-1 behavior of LLE. Distribution coefficients and separation factors were measured to evaluate the extracting capacity of the solvent. The consistency of the experimental tie-line data was determined through the Othmer–Tobias and Bachman equations. The raw experimental data were correlated using the NRTL and UNIQUAC models. The average root-mean-square deviation between the experimental and calculated mass fractions was 0.488% and 0.465%.

Experimental solubility curves and tie-line data for the (water + phenol + 2-ethyl-1-hexanol) system was obtained at T = 298.2 K and atmospheric pressure. The tie-line data was determined by techniques karl-fischer and refractometry. This ternary system exhibits type-2 behavior of LLE. Distribution coefficients and separation factors were measured to evaluate the extracting ability of the solvent. The consistency of the experimental tie-line data was determined through the Othmer–Tobias and Bachman equations. The data were correlated with the NRTL (a = 0.25) and UNIQUAC models and the parameters estimated present root mean square deviations below 0.50%.

AbstractThe liquid–liquid equilibrium (LLE) data for a ternary system {methyl eugenol + linalool +1-ethyl-3-methylimidazolium hydrogen sulfate [EMIM][HSO4]} (Meu-Lin-IL) were measured at 298.2 K and atmospheric pressure. The Othmer–Tobias correlation was used to verify the reliability of the experimental tie-line data. The solubility curves were obtained using the cloud point titration indicating the liquid-liquid equilibrium of the ternary system was in Type II class where two immiscible curve pairs were attained. Distribution coefficients, separation factors and selectivity were calculated for the immiscibility regions. The calculated results were compared with the experimental data. Characterization studies were performed by Fourier transform infrared spectroscopy (FTIR), thermal gravimetric analysis (TGA) and proton nuclear magnetic resonance spectroscopy (1H-NMR) techniques.

Liquid-liquid equilibrium data for the terna1y system water-ethanol-dimethyl adipate (dibasic ester) have been determined experimentally at 298.15±0.20, 308.15±0.20, and 318.15±0.20 K. Tie-line compositions were correlated by the Othmer-Tobias method. The UNIFAC method was used to predict the phase equilibrium in the system using the interaction parameters determined from experimental data between the CH3, CH2, OH, CH3COO and H20 groups. Distribution coefficients and separation factors were evaluated for the immiscibility region

Equilibrium Data

Isobaric equilibrium data (P = 101.3 kPa) for the system cyclohexane-acetic acid-propionic acid have been measured by two different analytical techniques. Activity coefficients calculated by simultaneous solving of equations for the chemical and phase equilibria were subjected to a consistency test based on inaccuracies determined from the error propagation law, and were correlated by Wilson’s equation. The activity coefficients measured were compared with those calculated from binary vapour-liquid equilibrium data and with values predicted by the UNIFAC method.
