Web11 apr. 2024 · The desolventizing of oil/solvent mixtures was strongly affected by solvent nature, and on the solute-solvent-membrane affinity. The highest retentions were observed for oil/ethanol mixtures, with values usually close to 100%, as a consequence of polarity as well as low solvation power. Web13 aug. 2024 · Update. I understand the "like dissolves the like"[] rule of thumb so that a highly polar solvent would be the worst for a non-polar molecule such as $\ce{CO2}$.Water as a solvent would then be the best choice (possibly salted to further reduce its $\ce{CO2}$ solubility) for my needs.. But as Rolf pointed out, the dissociation …
