Phase Equilibria of Benzyl Alcohol with Carbon Dioxide and Propane

An analysis of the phase behavior of binary systems is presented, including one of the representatives of aromatic alcohols (phenyl ethanol) and two potential extractants intended for use in the supercritical fluid (SCF) state. The study of the phase state of the thermodynamic systems “CO2–benzyl alcohol” and “propane–benzyl alcohol” in the near-critical region of the state has been carried out using a high-pressure optical cell. For the first time, data on phase equilibria of the “propane–benzyl alcohol” system have been obtained. The states of different phases are fixed.
