Solubilities of Hydrogen in Hexane and of Carbon Monoxide in Cyclohexane at Temperatures from 344.3 to 410.9 K and Pressures to 15 MPa

The solubilities of hydrogen in hexane and of carbon monoxide in cyclohexane were measured using a static equilibrium cell over the temperature range from 344.3 to 410.8 K and pressures to 15 MPa. The uncertainty in these new solubility measurements is estimated to be <0.001 in mole fraction. The data were analyzed using the Soave−Redlich−Kwong (SRK) and Peng−Robinson (PR) equations of state (EOS). In general, the two equations represent the experimental data within 0.002 mole fraction when a single interaction parameter ( C i j ) is used for each isotherm.
