Abstract
A wide-ranging study of imidazolium-based polymeric ionic liquids (PILs) as absorbents in two-phase partitioning bioreactor applications is presented, with a particular focus on the removal of n-butanol from dilute aqueous solutions. The study begins with a description of the synthesis and phase transition temperatures of poly(1-vinyl-3-alkylimidazolium) bromides bearing alkyl groups of different lengths, architecture, and composition, as well as analogs bearing various inorganic and carboxylate anions. Knowledge of polymer structure is used to generate insight into the solute affinity of each PIL, as quantified by the measurements of n-butanol partition coefficient (PCBuOH) and n-butanol/water selectivity (αb/w). These equilibrium experiments are extended to create a complete P[(VC12−linIm)(Br)]/n-BuOH/water ternary phase diagram that is used to propose a streamlined n-butanol recovery process.
