Liquid-Liquid Equilibria for the Ternary Systems of FC3283+HFE7300+Hexane, FC3283+HFE7500+Octane, and FC72+HFE7100+(Acetonitrile or Ethyl Acetate) at 273.15 K, 298.15 K, and 313.15 K

Abstract

The temperature-induced phase behavior of a ternary system consisting of two fluorinated solvents and an organic solvent was studied. The solubility data and liquid liquid equilibrium data for the following ternary systems were examined: (FC3283 + HFE7300 + hexane) at 273.15 K and 298.15 K, (FC3283 + HFE7500 + octane) at 298.15 K and 313.15 K, (FC72 + HFE7100 + acetonitrile) at 273.15 K and 298.15 K, and (FC72 + HFE7100 + ethyl acetate) at 273.15 K and 298.15 K. In addition, the experimental tie line data for eight ternary systems were correlated using the NRTL and UNIQUAC models, and the corresponding binary interaction parameters were determined.
