Vapor−Liquid Equilibria for the Carbon Dioxide + Pentane and Carbon Dioxide + Toluene Systems

Abstract

Vapor−liquid equilibrium data have been measured for the systems carbon dioxide + pentane at (310.15, 333.15, and 363.15) K and carbon dioxide + toluene at 323.15 K and 333.15 K. The experimental data have been correlated by the Peng−Robinson equation of state with one interaction parameter. In addition, the group pair parameters relating to CH2 + CO2 and ArCH + CO2 in the PRASOG group contribution model are determined.
