Synthesis and Characterization of Oil Lubricant Antioxidant Degradation Products
Bibliographic record
Abstract
Antioxidants are an example of additives added to lubricants as a sacrificial substance, which extend the lifespan by preferentially being oxidized over the lubricant. GasTops Ltd. is interested in predicting the remaining life of a lubricant by monitoring the quantity of antioxidant degradation products. An antioxidants of interest is N-phenyl-1-aminonaphthalene (PAN). Three major oxidation products of PAN have been identified, synthesized, and isolated: C-C coupled PAN dimer, C-N coupled PAN dimer, and naphthyl oxidized PAN (Fremy’s PAN). Other products include N-O radical PAN and phenyl oxidized PAN. Attempts to independently synthesize samples of these PAN derivatives resulted in the unexpected syntheses of other known PAN derivatives. Preparation of C-C PAN resulted in the synthesis of Fremy’s PAN as a by-product. Synthesis of C-N PAN resulted in the synthesis of C-C PAN and Fremy’s PAN. Synthesis of N-O radical PAN resulted in the production of C-C PAN and Fremy’s PAN.

How this classification was reachedexpand
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.
