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 cyclohexan e 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 da ta were analyzed using the Soave-Redlich-Kwong (SRK) and Peng-Robinson (PR) equations of state (EOS). In general, the two equations represent the expe rimental data within 0.002 mole fraction when a single interaction paramete r (C-ij) is used for each isotherm.
