This study reveals thermodynamic insights into phase behavior in aqueous two-phase systems, suggesting that MIL structure significantly impacts outcomes.
This study investigates the phase behavior and thermodynamics of aqueous two-phase systems (ATPSs) formed with cholinium-based magnetic ionic liquids (MILs). Three MILs were synthesized and characterized, demonstrating their efficacy in forming magnetically responsive ATPSs for advanced separation applications. Phase diagrams were determined for MIL-ATPSs [N11n(2OH)][TEMPO-OSO3] (with varying alkyl chain lengths), salts, and water across different temperatures. Binodal data were accurately fitted using the Merchuk equation. Results reveal that MIL structure, temperature, and salt type profoundly affect phase behavior. Structural features and viscosity of the MILs significantly influence phase formation. The salting-out effect emerged as the key driving force, correlating with salt hydration thermodynamics (ΔhydG and ΔhydS). These findings provide valuable experimental and theoretical insights to advance responsive separation technologies
