Abstract
Liquid–liquid equilibrium data for ternary systems hexafluoroisopropanol + perfluorocarbon (namely perfluoro(n-hexane) or perfluoro(methylcyclohexane)) + water or methanol were determined at 298.15 K. Water, methanol, and other polar solvents exhibit very low miscibility with perfluorocarbons. In contrast, hexafluoroisopropanol is fully miscible with water, methanol, and perfluorocarbons. Consequently, the determined ternary liquid–liquid equilibrium diagrams possess only one heterogeneous binary subsystem. They are of the type 1. Due to specific properties of perfluorocarbons, a special procedure for determination of the liquid–liquid equilibrium in the studied systems was developed. The ternary liquid–liquid equilibrium diagrams were found to be almost identical for perfluoro(n-hexane) and perfluoro(methylcyclohexane) showing that the structure of perfluorocarbon component has minimal influence on the miscibility behavior.
