Abstract

A flow-type apparatus was constructed to measure the solubilities of coal-derived components in supercritical fluids. To determine the reliableness of the apparatus, the solubilities of naphthalene in supercritical carbon dioxide were measured at 308 K and 328 K up to 25 MPa. It was found that the resulting solubility data agreed well with the experimental results from other investigators. It was also found that the data could be correlated by using a three-constant cubic equation of state with two interaction parameters introduced in the conventional mixing rules for the constants.
