A new experimental technique was developed to determine the solubilities of organics in supercritical fluids. Solubilities are determined by determining the weight of organic deposited on activated carbon when a stream of organic and carbon dioxide is passed through the carbon bed. The solubility of naphthalene in carbon dioxide at 308, 318, and 328 K at around 105 bar was determined and was found to be in good agreement with the data reported in the literature. In addition, the method was used to determine the solubilities of hexachlorobenzene and pentachlorophenol in carbon dioxide at 298, 308, and 318 K at 111.5 bar. The solubility data were correlated using a simple model relating the solute solubility and the solvent density.
