โœฆ Synopsis

Predictions are given for the solubilities of four compounds (naphthalene, phenanthrene, phenol, and 2-naphthol) in carbon dioxide at six temperatures between 40 "C and 100 "C and pressures up to 240 bar. The data are intended to be relevant to the extraction of coal-gasification tars. The Peng-Robinson equation-of-state was used for predictions. Temperature-dependent interaction parameters were obtained using, where possible, the published solubility data.

Dioxins and dibenzofurans are suspected to be quite toxic. They are fat soluble, and therefore, accumulate in fat-rich tissues (e.g., fish liver) and in products like milk. They have been detected in a large amount of food raw materials. Therefore it is urgent to find ways to purify such materials.

A new experimental method has been developed for measuring the equilibrium solubility of heavy solutes in supercritical CO2. The micro-SFE (supercritical-fluid extraction) is coupled to supercriticalfluid chromatography (SFC), both operating under the same temperature, pressure, and CO2 flowrate. Na
