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).

“…At 101.3 kPa, the experimental LLE data were obtained at 303.2, 313.2, and 323.2 K. The information of apparatus and means has been provided in previous papers. − First, the solvent (TCM or MIPK) and water, each weighing about 40 g, were loaded into a jacketed glass container and mixed for 4 h and then stabilized for at least 6 h. Next, FAL was added to the kettle several times (1–2 g each time) to determine different phase equilibrium points. A thermocouple thermometer was used to measure the temperature of each test system, with an accuracy of 0.1 K.…”

The liquid–liquid equilibrium (LLE) data of water + furfuryl alcohol + trichloromethane /methyl isopropyl ketone were determined at 303.2, 313.2, and 323.2 K under 101.3 kPa. The distribution coefficient (D) and separation factor (S) were evaluated for the separation effect of solvents. The nonrandom two-liquid and universal quasichemical models were used to correlate the experimental LLE data and obtain the binary interaction parameters. Meanwhile, the root mean square deviations and absolute average deviation of the two models did not exceed 0.0094 and 0.0066, respectively, which shows that the experimental LLE data can be accurately correlated through the two models. GUI-MATLAB was used to verify the consistency between the LLE data and the calculated binary interaction parameters. σ-Profiles were used to analyze the interaction between the molecules of each substance, further confirming the accuracy of the experimental results.

Liquid–liquid equilibrium (LLE) data for the ternary mixture of water + 2,2,3,3-tetrafluoro-1-propanol (TFP) + {1-pentanol or 2-ethyl-1-hexanol or n-propyl acetate or dichloromethane} was measured in 101.3 KPa and 303.2 K. The distribution coefficient and separation factor appraised utility for extracting TFP from water. The experimental LLE data were related by the nonrandom two liquid and universal quasichemical models for which the absolute average deviation and root means square deviation were no more than 0.0029 and 0.0035, respectively.
