High-pressure gas solubility in mixtures with one compound being an „alternative“ solvent
- The term „Alternative Solvents“ often refers to ionic liquids (ILs), mainly to distinguish these substances from traditional (i.e., molecular) solvents. In applications, any „alternative“ is required to perform better than something that is proven and tested. To bring ILs into practical use, availability and costs are the fundamental points to be addressed. There are two ways to proceed: ▬ tailoring a molecule, implanting the expected characteristics advantage: optimization of the targeted performance possible risks: outcome not always foreseeable, costly and time-intensive (“trial and error“) ▬ to target on mixtures of well-characterized ILs with molecular solvents advantage: substance characteristics are known, less costly, less time-consuming, mixture composition another tunable parameter risks: the same but with less impact For the basic engineering of technical processes, knowledge of phase equilibria, particularly of mixtures, over a broad (p,T) range isThe term „Alternative Solvents“ often refers to ionic liquids (ILs), mainly to distinguish these substances from traditional (i.e., molecular) solvents.

This contribution reports on recent experimental results from our laboratory: ▬ the solubility of CO2 in a mixture of water and [bmim][CH3SO4] ▬ the solubility of CO2 in a mixture of methanol and [bmim][PF6]…
