SEARCH Articles Figures Tables The solubility of naphthalene in supercritical carbon dioxide as a function of pressure. The points and are the experimental data of McHugh and Paulaitis 7. Chem. Eng. Data, 25, 326 at 7 35.0 and 60.4 C, respectively. The lines are the correlations of the data using the Peng-Rpbinsoti equation of state with kcoz-u 0.103. Note the sharp increase in naphthalene solubility with pressure near the CO2 critic pressure of 73.76 bar. [Publishers Imprint]
