Solubilities of carbon dioxide in normal paraffins

Abstract

The solubilities of carbon dioxide in 18 normal paraffin solvents are modelled by the Soave equation of state with one interaction parameter. Henry's constant, the partial molar volume at infinite dilution and the Margules constant are evaluated from the above parameters using Bender et al.'s (Fluid Phase Equilib., 15 (1984) 241) approach and these properties are shown to be dependent on temperature and the carbon number of normal paraffins.
