Liquid–Liquid Equilibria Data and Thermodynamic Modeling for the Ternary System of Water, 2,2,3,3-Tetrafluoro-1-propanol, and Different Solvents

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.
