“…And there is also an evident decreasing tendency shown in distribution coefficients and separation factors with the increasing of cresol's concentration in the aqueous phase or in the organic phase at a certain temperature, indicating that concentration also put a vital effect on the distribution ratios of cresol among organic phase and aqueous phase and on the separation factors. Such temperature and concentration dependence could also be commonly observed in many other ternary systems, especially phenols containing systems [34][35][36][37][38][39]. It can also be seen from figures 7 and 8 that, the influence of the structure of cresol isomers on the extractive properties of 2-pentanone is insignificant, as the distribution coefficients and separation factors are very close for the three cresol isomers when using 2-pentanone as the extraction agent.…”

The (liquid + liquid) equilibrium (LLE) data are vital for the liquid extraction of cresols from aqueous solution with 2-pentanone as an extraction agent. Therefore, the ternary LLE data for {2-pentanone + o-cresol, m-cresol or p-cresol + water} were determined at T = (298.15 and 323.15) K and p = 101.3 kPa. And the reliability of the LLE data was ascertained by using the Othmer-Tobias and Hand equations. The distribution coefficients and separation factors were calculated to evaluate the effectiveness of extracting cresols from water. The thermodynamic NRTL and UNIQUAC models were used to correlate the experimental LLE data of the studied systems, and the binary interaction parameter values were obtained from the data correlation.

For separating 2-butanone and water from the azeotropic system, the liquid−liquid equilibria (LLE) data for the ternary mixture of solvents (p-xylene, mesityl oxide) + 2-butanone + water at 298.2, 303.2, and 313.2 K were obtained under 101.3 kPa. The distribution coefficient (D) and selectivity coefficient (S) were used to evaluate the effect of extracting 2-butanone from water, it is found that p-xylene is better than mesityl oxide. The Bachman and Othmer−Tobias equations were used to verify the reliability of the LLE data with the linear coefficient being greater than 0.98%. The NRTL and UNIQUAC models successfully correlated the experimental data with the root mean square deviation values less than 0.87 and 0.50%, respectively. It shows that the UNIQUAC is more suitable for this system than the NRTL model.

In a previous work, the binary systems for water + p -xylene were described and studied . The mutual solubility measurement was repeated at least five to six times with a relative standard deviation (RSD) lower than 4%.…”

Biomass is known as a potential renewable energy source which can be used in the gasification process in order to produce biomethane gas. One of the major challenges encountered is the elimination of the high level of tar found in the syngas issued from the gasification process. The main purpose of this work is to conduct experimental measurements of liquid−liquid equilibria that will be used for tar removal from the biomass gasification process which is the important step before the distribution and the industrialization of the biomethane gas. In the present work, we propose an experimental and modeling study of liquid− liquid equilibrium of ternary systems of water + solvent (methyl oleate) + model molecules of tar (benzene, toluene, phenol, thiophene, and pyridine) at 303.2 K, 323.2 K, and 343.2 K. The experimental results were correlated using the nonrandom two-liquid (NRTL) and UNIQUAC models and are used to feed the industrial needs for thermodynamic modeling.
