摘要：

New experimental data are presented for the solubility of several solid solutes and solute mixtures in entrainer-doped supercritical fluid carbon dioxide. These results, along with others from the literature, are used to demonstrate the effects of solute size (appreciable) and solute polarity (small) in pure supercritical fluids. Solvent effects appear to be far more important than solute structure, and polar and hydrogen-bonding entrainers exhibit large effects on both solute loading and selectivity. Thus, it appears that entrainers can be used to tailor supercritical fluid solvents for specific applications.
