Polymeric ionic liquid absorbents for <scp><i>n</i>‐butanol</scp> recovery from aqueous solution
Bibliographic record
Abstract
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 (PC BuOH ) and n ‐butanol/water selectivity ( α b/w ). These equilibrium experiments are extended to create a complete P[(VC 12−lin Im)(Br)]/ n ‐BuOH/water ternary phase diagram that is used to propose a streamlined n ‐butanol recovery process.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
