A review of the solubility data for solids in sub- and supercritical fluids published in the literature between 2010 and 2017 is presented, including the pressure and temperature ranges and correlation methods. Compounds are categorized into the following groups: pharmaceutical, biological, aromatic, nonaromatic, organometallic, and polymer. The most commonly used solvent is supercritical CO2; some data have also been published for other solvents, such as argon, propane, and fluorinated hydrocarbons.

The ability to predict the behaviour of high-pressure mixtures of carbon dioxide and alcohol is important for industrial purposes. The equilibrium composition of three binary carbon dioxide-alcohol systems was measured at temperatures of 313.15 K and 333.15 K and at pressures of up to 100 bar for carbon dioxide-2-propanol, up to 160 bar for carbon dioxide-1-butanol and up to 150 bar for carbon dioxide-2-butanol. Different equilibrium compositions of carbon dioxide in alcohols were observed despite their similar molecular weight (M2-propanol = 60.100 g mol−1, M1-butanol = 74.121 g mol−1 and M2-butanol = 74.122 g mol−1) and place in the functional hydroxyl group (first or second carbon molecule). It is assumed that the differences in the phase equilibria are due to different vapor pressures, polarities and solute-solute interactions.

High-pressure phase equilibrium (vapor−liquid and solid−supercritical fluid phase equilibria) data for three binary systems were determined at two temperatures (313.15 and 333.15 K) and at pressures of carbon dioxide of up to 250 bar for tetrabutylurea/carbon dioxide, up to 200 bar for tetramethylurea/carbon dioxide, and up to 110 bar for tetramethylthiourea/carbon dioxide using a variable-volume high-pressure optical view cell. The measurements have been performed for all of the three systems at a constant temperature with increasing pressure. Furthermore, a melting point curve (solid−supercritical fluid phase equilibrium) of the solid sample tetramethylthiourea was determined using the modified capillary method in a high-pressure optical view cell at a pressure of carbon dioxide of up to 300 bar. The highest mutual solubilities for these binary systems under the same process conditions were in the following order: tetrabutylurea/carbon dioxide > tetramethylurea/carbon dioxide > tetramethylthiourea/ carbon dioxide. The results determined with the modified capillary method showed that at a pressure higher than 10 bar, the liquefaction temperature decreased significantly.
