Studies on <i>para</i>‐selectivity and yield enhancement in zeolite catalyzed toluene nitration
Bibliographic record
Abstract
Abstract The nitration of toluene using solid acid catalyst is carried out in batch and semi‐batch reactors with or without continuous water withdrawal. The effect of process parameters viz., nature of catalyst, agitation speed, nitric acid‐toluene dispersion morphology, catalyst to toluene ratio, temperature, nitric acid dosing and boil‐up rates (BRs) on overall conversions, and para ‐selectivity is investigated. The micro‐reaction environment around the catalyst particle and its influence on lattice aluminum transformation to achieve improved para ‐selectivity has received special attention. These studies have established the importance of dispersion morphology of reactants and microenvironment around catalyst particles for achieving preferred conversion and para ‐selectivity in toluene nitration.

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.
