Abstract
The extraction for three isomers of bisphenol F (BPF) was studied in a hydrophobic ionic liquid/water biphasic extraction system. The influences of some factors, such as ionic liquid structure, phase ratio, temperature, pH value, and NaCl concentration on the extraction of BPF three isomers were investigated, and excellent efficiency with more than 99.0 % extraction efficiency was obtained using 1‐octyl‐3‐methylimidazolium tetrafluoroborate ([Omim][BF 4 ]) as an extractant. The extraction mechanism of the hydrogen bonds interaction between [Omim][BF 4 ] and BPF three isomers were proven by 1 H‐NMR spectrum and the density functional theory (DFT). From the 1 H‐NMR spectrum, the immediate disappearance of the BPF isomer hydroxyl protons upon addition of [Omim][BF 4 ] was found, which indicated the existence of hydrogen bond interaction between BPF isomer and [Omim][BF 4 ]. Through the computer simulation, the hydrogen bonds strength decreased in the order of 2,2′‐BPF > 2,4′‐BPF > 4,4′‐BPF, which is consistent with the descending order of distribution coefficients obtained through the experiments. These results are promising for the liquid‐liquid extraction and enrichment of phenols in related industrial processes.

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
