Abstract
In this paper, we synthesized a novel structure of sulfoxide, benzyl 2‐ethylhexyl sulfoxide (BSO), and evaluated its performance for extracting phenol. The influences of several variables on phenol extraction were investigated, including equilibrium time, pH value, temperature, and salts in the aqueous phase. It was found the BSO dissolved in kerosene was an effective extractant for the recovery of phenol from an aqueous solution at pH = 2. The transfer mechanism of phenol into the organic phase was proved to be the solvation reaction by BSO through hydrogen bonds as a phenol: BSO 1:1 complex. The temperature variation tests showed that the extraction process is exothermic, and phenol extraction efficiency decreased with increased reaction temperature. Phenol could be efficiently stripped from the loaded organic phase with a sodium hydroxide solution. The results obtained establish that the BSO/kerosene system has potential for practical applications in the recovery of phenol from aqueous solutions.

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
