Abstract
Abstract The kinetics for hydrolysis of isoamyl DL‐lactate over cation‐exchange resin NKC‐9 was investigated in this paper, which was the prerequisite for a proper design of reactive distillation processes. The effects of mass transfer resistance, temperature, catalyst dosage, and the molar ratio of water to isoamyl DL‐lactate on conversion of isoamyl DL‐lactate were evaluated. The pseudo‐homogeneous (PH), Eley‐Rideal (ER), and Langmuir‐Hinshelwood (LH) models were then utilized to correlate the data obtained from experiments. Activities were used in the kinetics instead of the mole fractions because the reactants and products were not ideal. The activity coefficients were estimated by UNIFAC. It was demonstrated that the PH model was the best one to describe the hydrolysis of isoamyl DL‐lactate. The standard enthalpy was 5.46 kJ · mol −1 and the activation energy was 59.71 kJ · mol −1 . Finally, the thermal stability and reusability of NKC‐9 were also tested.

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
