Abstract

fetched live from OpenAlex

Abstract Ionic liquids (ILs) are being considered as favourable solvents for liquid‐liquid extraction. Ternary phase equilibria containing the ionic liquid based systems have been reported in the literature for aromatic‐aliphatic‐IL as well as aliphatic‐alcohol‐IL ternary systems. In this work global optimization has been used for the prediction of UNIQUAC interaction parameters for IL based systems. The twin concepts of closure equation and global optimization via Genetic Algorithm (GA) have been benchmarked and tested on 88 aromatic and 28 hydrogen bonding multi‐component systems. For the aromatic systems the rmsd values obtained with closure equation are ∼20 percent better than without closure equation and ∼50 percent better than literature. Similarly for hydrogen bonding systems with closure equation gives ∼20 percent better rmsd values than without closure equations with an overall improvement of ∼60 percent. After this rigorous testing we have applied this procedure on 29 imidazolium based IL ternary systems. Improvements in rmsds with closure have been ∼6 percent better than without closure.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
