Abstract
Cyclohexanone oxime serves as a crucial intermediate in the synthesis of caprolactam, which is an essential precursor for manufacturing nylon fibers, high-performance engineering plastics, and specialized plastic films. Catalytic hydrogenation of nitrocyclohexane to cyclohexanone oxime has been documented to be an atom-economical, green and environmentally friendly process. In this review, we first introduce the current design rules of catalysts for catalytic hydrogenation of nitrocyclohexane in terms of both active metals and supports. Secondly, we discuss the influence of solvent effects on the cyclohexanone oxime from the nitrocyclohexane conversion. In addition, we concisely discuss typically proposed reaction pathways for the hydrogenation of nitrocyclohexane to produce cyclohexanone oxime. Finally, we provide our perspectives on some issues for catalytic conversion of nitrocyclohexane to cyclohexanone oxime in the future.

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
