Abstract
Abstract A novel three‐stage catalytic reactive distillation (RD) column integrated chemical reaction and distillation process for the continuous synthesis of ε‐caprolactone (ε‐CL) was proposed to overcome the disadvantages of previous batch processes. Reaction kinetics according to the two‐step indirect oxidation method was studied firstly, which was essential in reactor design and process optimization as well as lacking in the current literature. Kinetics models obtained by data fitting were tested by residual distribution and model statistics. And then, according to the thermodynamic characteristics and reaction kinetics of this process, a steady‐state simulation of RD column was carried out with the process simulator Aspen Plus. The influence of operation parameters was investigated on process performance. Under the optimal operating conditions, the conversion of cyclohexanone was 97%, and the mass fraction of ε‐CL in the bottom products was 62.31%. The simulation showed that RD column worked with excellent results in respect to conversion and product purity because of integrating the processes of chemical reaction and distillation.

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
