PVT Data and Phase Equilibrium of the Ionic Liquid–n-Hexane System at High Temperatures and Pressures

Resumo

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.
