$PVT$ data and phase equilibrium of the ionic liquid–n-hexane system at high temperatures and pressures

Analyses of $PVT$ data (with a constant-volume piezometer) and the phase equilibria of an n-hexane–ionic liquid $(10\%)$ binary system have been performed in the temperature range of $300$–$575$ K at pressures up to $16$ MPa. The liquid–liquid and liquid–gas phase-equilibrium lines and critical parameters of the studied system are obtained.
