摘要：

The solubility of a family of disubstituted aromatic isomers, the hydroxybenzoic acids, was measured in supercritical carbon dioxide at 373 K over a pressure range of 200-400 bar; the solubility of another family, the dihydroxybenzenes, was measured at 328 K and at one pressure, 310 bar. The solubility within a family was found to be a function of the melting point of the isomer, the lower the melting point, the higher the solubility. The results suggest that supercritical solvents can be used to separate certain ortho and para isomers.
