Vapor-liquid phase coexistence of alkane-carbon dioxide and perfluoroalkane-carbon dioxide mixtures
Article Abstract:
A molecular simulation of the vapor-liquid equilibria of alkane-CO2 and perfluoroalkane-CO2 binary mixtures was conducted by using the Gibbs ensemble Monte Carlo technique. Simple interaction site models and the conventional Lorentz-Berthelot rules for the cross interaction between the solute and solvent species with no adjustable parameters were employed to predict the vapor-liquid phase equilibrium of the hexane-CO2 and perfluorohexane-CO2 mixtures. The model predicted a higher solubility for the perfluoralkanes in CO2 in comparison with alkanes in CO2. Simulation results indicated that the dispersion interaction and the geometric packing may have a significant role in accounting for the solubility difference between alkane and perfluoroalkane in CO2.
