Vapour phase selective oxidation of 2‐methylnaphthalene to 2‐methyl‐1,4‐naphthoquinone on composite vanadium catalyst
Bibliographic record
Abstract
Abstract The selective vapour‐phase oxidation of 2‐MN to 2‐MNQ was investigated effectively in the presence of a composite vanadium catalyst. The catalyst was prepared by impregnation. It was characterized by XRD, BET, SEM, etc. The activity of the catalyst was tested in a fixed bed reactor by the selective oxidation of 2‐MN to 2‐MNQ, and the process conditions were optimized. The proper reaction temperature was 663 K, the space velocity was 200 mL · (g · min) −1 , and the material flow was 3 μL · min −1 . The 2‐MN conversion rate was 80.01 %, and the yield of 2‐MNQ was 45.84 %. Compared to previous procedures for this type of reaction, the reaction is more environmentally friendly and is suitable for large‐scale industrial production.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
