摘要：

New data fur the solubility of five three- to five-ring polynuclear aromatic hydrocarbons, anthracene, phenanthrene, triphenylene, chrysene and perylene, in supercritical carbon dioxide are reported. Measurements were obtained with a recirculating high-pressure system employing on-line monitoring to verify equilibrium. The influence of water and the role of methanol as a solubility enhancer were investigated. Heats of Solution and Heats of Mixing were calculated from van't Hoff plots. Van't Hoff methodology also served to demonstrate the consistency of the data.
