Industrial processes such as petroleum refining, coal conversion, enhanced oil recovery, and supercritical separation have created great demand for phase equilibrium data for asymmetric mixtures. The solubilities of hydrogen in decane, eicosane, octacosane, and hexatriacontane were measured using a static equilibrium cell over the temperature range from 323.2 to 423.2 K and pressures to 17.4 MPa. The uncertainty in these new solubility measurements is estimated to be less than 0.001 in mole fraction. The data were analyzed using the Soave-Redlich-Kwong (SRK) and Peng-Robinson (PR) equations of state. In general, the two equations represent the experimental data well when a single interaction parameter is used for each binary system. The present data suggest that the interaction parameter, C[sub ij], is highly temperature dependent, and that the use of a second interaction parameter, D[sub ij], is not merited.
