For separating the special phenolic compound 2,6-xylenol from the model coal tar, the liquid–liquid equilibrium data regarding the four mixtures (toluene + 2,6-xylenol + glycerol/ethylene glycol/1,4-butanediol/1,3-propanediol) were measured at 303.15 K under pressure 0.1 MPa. The separation performance of the selected solvents was assessed by distribution coefficient (D) and separation factor (S). The experimental and calculated results showed that glycerol and ethylene glycol were suitable solvents. Meanwhile, the reliability of the measured data was checked by the Hand and Othmer–Tobias methods. In addition, the NRTL and UNIQUAC thermodynamic models were adopted to correlate the experimental data with the calculated values of root-mean-square deviation (RMSD) and absolute average relative deviation (AARD) lower than 0.01. The consistency of the regressed binary interaction parameters was verified using a tool GUI-MATLAB.

To explore the separation of formaldehyde from its aqueous solution, the liquid–liquid equilibrium data for the systems (water + formaldehyde + methyl isobutyl ketone/cyclohexanone) were measured at 303.15, 313.15, and 323.15 K in 101.3 kPa. The separation effect was judged by the separation factor and the partition coefficient. The S values of methyl isobutyl ketone and cyclohexanone are greater than unity, and the S and D values of cyclohexanone are greater than methyl isobutyl ketone, indicating that cyclohexanone is a suitable extractant compared with methyl isobutyl ketone. The reliability of the measured data is evaluated by Hand and Othmer–Tobias equations, and the R 2 values of the two equations are close to unity. The universal quasi-chemical theory and nonrandom two-liquid theory models were applied to fit the tie-line data of the investigated mixtures with a root mean square deviation lower than 0.01. Moreover, the binary interaction parameters were validated using a topology of Gibbs energy of mixing surface analysis.

BACKGROUND 2,2,3,3‐Tetrafluoro‐1‐propanol (TFP) is a benign solvent and widely used in the electronics industry as a cleaning agent. Because water and TFP can form an azeotropic mixture, it consumes energy to separate TFP from its aqueous mixtures using conventional distillation. RESULTS In this work, the zeolitic imidazolate framework‐8 porous ionic liquid (ZIF‐8‐PIL) and the ionic liquid (IL) N‐butyl pyridinium bis(trifluoromethyl sulfonyl) imide ([Bpy][NTf2]) are used as extractants to extract TFP from its aqueous solution. ZIF‐8‐PIL was synthesized by ZIF‐8 and IL [Bpy][NTf2]. The liquid–liquid equilibrium (LLE) data for the two systems (water + TFP + ZIF‐8‐PIL/IL) were determined at 298.15, 308.15 and 318.15 K under 101.3 kPa. The selectivity (S) and distribution coefficient (D) were examined to assess the extractive performance of ZIF‐8‐PIL and IL. The non‐random two‐liquid (NRTL) model was applied to fit the tie‐line data of the investigated mixtures. CONCLUSION The results demonstrate that ZIF‐8‐PIL is a suitable extractant to separate TFP with values of S and D greater than unity. The NRTL model has better correlation performance for the ternary systems with root mean square deviation lower than 0.01. The obtained parameters satisfy the minimum state of the mixed Gibbs free energy, which indicated that the model parameters are reliable. © 2021 Society of Chemical Industry (SCI).
