Hello everyone, I have a question about properties of 2 different solvents. For little context, I have a homework about liquid-liquid extraction so I had to compare which solvent is better for the acetic acid extraction. The first solvent I compared was Diisopropyl Ether and the 2nd was Butyl Acetate. By fiding the stage number I got 3 stages for Diisoproyl and 2 stages for Butyl acetate so the butyl should be better, but I think that in a theorical way by looking at solubilities and volatilities, the diisopropyl should be better. Looking forward to your answers. Thank you! I'm still learning about this topic
Partitioning in liquid-liquid extraction is easy to correlate to Hansen solubility parameters. In this case, you have tabulated parameters for all these solvents that are easy to look up and you correlate the phase equilibrium constant to the Euclidean radius from a fitted center point. This is all explained in Book BioSeparations
