Abstract
An efficient and simple process for the dehydration of xylose into furfural was studied, which was catalyzed by 1-(4-sulfonic acid)butyl-3-methylimidazolium hydrogen sulfate (IL-1) under mild conditions. A xylose conversion of 95.3% with a furfural yield of 91.45% was achieved in a 25 min reaction time at 150 °C; the xylose conversion and furfural yield greatly depended on the operation conditions, such as reaction time and temperature. IL-1 could be recycled and exhibited constant activity for five successive trials. This system was an important improvement, relative to the reactions using mineral acids at high temperatures, for further development on a pilot scale.

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
