Abstract

fetched live from OpenAlex

The solvent extraction has been successfully applied to the recovery of methyl-substituted 1,3-dioxane from the aqueous reaction media. Aromatic hydrocarbons used as extractants allowed the removal, from the aqueous phase, of up to 75% of dioxane formed in the one stage reactor–extractor. The concept could be included in a downstream separation scheme for the isolation of 1,3-propanediol from a dilute aqueous solution using reversible reaction of the diol with acetalaldehyde.

Teacher imitation

Not 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.
