Effect of Ozone and Sulfur Dioxide on the Photolytic Degradation of Chlorobenzene in Air
Bibliographic record
Abstract
The simplest chlorinated aromatic compound, chlorobenzene, was selected as a model organic pollutant to examine the photochemical destruction process in the gas phase, for potential application to flue gas treatment where oxygen, water, and sulfur dioxide may also be present. The degradation products under various reaction conditions were detected and found to include benzene, phenol, chlorophenol, chlorobiphenyls, HOCl, and HCl. The degradation pathways were elucidated based on the detected products and the literature. It was confirmed that dechlorination occurs before the aromatic ring is broken and that biphenyls can be formed. However, in the presence of added ozone, the formation of chlorobiphenyls was suppressed. The presence of sulfur dioxide resulted in attachment onto the aromatic ring, as confirmed by the S–C bond in the FTIR spectrum, and the formation of a benzenesulfonic acid intermediate.

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.
