Solubility of polynuclear aromatic hydrocarbons in supercritical carbon dioxide
1Department of Chemical and Biochemical Engineering, Rutgers, State University of New Jersey, P.O. Box 909, Piscataway, New Jersey 08855-0909, USA.
Abstract:
New data for 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.

Physical Properties Affecting Solubility
As for any solution, the solubility of a gas in a liquid is affected by the attractive intermolecular forces between solute and solvent species. Unlike solid and liquid solutes, however, there is no solute-solute intermolecular attraction to overcome when a gaseous solute dissolves in a liquid solvent since the atoms or molecules comprising a gas are far separated and experience negligible interactions. Consequently, solute-solvent interactions are the sole...
Solubility
A solution is a homogeneous mixture composed of a solvent, the major component, and a solute, the minor component. The physical state of a solution—solid, liquid, or gas—is typically the same as that of the solvent. Solute concentrations are often described with qualitative terms such as dilute (of relatively low concentration) and concentrated (of relatively high concentration).
In a solution, the solute particles (molecules, atoms, and/or ions)...
