The object of this work is the isobaric vapour-liquid equilibrium (at 101.32 kPa) and the liquid-liquid equilibrium (at 30 and 50°C) in the ternary tetrahydrofuran-n-hexane-water system. Further, the isobaric vapour-liquid equilibrium (at 101.32 kPa) in the binary tetrahydrofuran-n-hexane and tetrahydrofuran-water systems has been established. The experimental data obtained have been fitted to the Redlich-Kister equation. The constants of the correlation relation determined from the data on the vapour-liquid equilibria have been proved to provide an adequate description of the liquid-liquid equilibrium.
