Kinetics of Catalytic Ozonation of Methyl <b><i>tert</i></b>‐Butyl Ether in the Presence of Perfluorooctyl Alumina
Bibliographic record
Abstract
Abstract In this work, the kinetics of heterogeneous ozonation of methyl tert‐butyl ether (MTBE) in the presence of perfluorooctyl alumina (PFOAL) catalysts is presented. Activity of the PFOAL catalysts in ozonation reactions of MTBE was studied in a batch reactor over the temperature range of 25 to 40 °C. The results show that PFOAL is an effective catalyst for enhancing the molecular mechanism of ozone reactions. For a catalyst concentration of 5 g/L, the contribution of the rate of heterogeneous catalytic reaction in the total reaction rate is about 50 %, 75 %, and 85 % at the reaction temperatures of 25 °C, 30 °C, and 40 °C, respectively. Kinetic studies showed that the chemical reaction of ozone and MTBE is the controlling step in this catalytic system. The quasi‐homogeneous kinetic model proved to be an appropriate approach in modeling the heterogeneous reaction of ozone with MTBE on PFOAL catalysts.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
