Abstract
Abstract This article proposes for the first time the preparation of a series of amino acid ionic liquids (AAILs) via one‐step hydrolysis of cheap lactams for the capture of CO 2 . The structures of the prepared AAILs are confirmed using NMR, FTIR, and ESI‐MS, and their physical properties are also determined. It is found that these AAILs are reversible CO 2 absorbents with very high absorption capacities (0.15 to 0.18 g·g −1 at 313.2 K and 1.0 bar), better than almost all task‐specific ionic liquids reported in literatures. The absorption mechanism is also elucidated to be a combination of 1:1 and 2:1 stoichiometric reaction of AAILs with CO 2 from NMR, FTIR, reaction equilibrium thermodynamical modeling and quantum calculations. The AAILs have the advantages of simple synthesis, high yield, and using available cheap raw materials. It is believed that this kind of AAILs have great potentials to be used as efficient CO 2 absorbents.

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 it
