Liquid–liquid equilibria containing fluorous solvents as environmentally benign solvent

The object of this study is to measure the liquid–liquid equilibrium (LLE) data in fluorous solvent (perfluorohexane and Galden® HT-135) mixtures, which are used as environmentally benign reaction solvents. The LLE data of perfluorohexane + n-alkane (C7, C9, and C10) mixtures were measured to determine the phase behavior of perfluorohexane + n-alkane (C6–C10) mixtures. The LLE for Galden HT-135® + dibutyl ether/butyl acetate mixtures were measured up to the upper critical solution temperature (UCST). The experimental results for the LLE were represented using the NRTL activity coefficient model.

► This study investigates measurements of LLE data containing two fluorous solvents.
► Perfluorohexane and Galden® HT-135 were investigated as fluorous solvent.
► LLE data of mixtures perfluorohexane + n-alkane (C7, C9, and C10) were measured.
► LLE data of mixtures Galden HT-135® + dibutyl ether / butyl acetate were also measured.
► Experimental LLE data were represented by NRTL model.
