Abstract
A toolbox approach for the transfer of batch to continuous chemical synthesis is presented. The approach considers reaction kinetics (Type A, B, C), reacting phases (single phase, liquid–liquid, gas–liquid and liquid–solid), and the reaction network (parallel and consecutive reactions) in order to select the most appropriate reactor module (Plate, Coil, or CSTR) for continuous operation. Then, three case studies using these three fundamental reactors are presented but require special considerations. For the reaction of dimethyl-oxalate with ethylmagnesium chloride, a plug-flow multi-injection technology must be used to decrease the local heat generation and improve yield. For the nitration of salicylic acid, a Plate reactor with mixing elements favoring some back-mixing followed by a plug-flow system at elevated temperatures is used instead of a tandem mixed-flow CSTR and plug-flow Coil reactor in order to minimize the risk of thermal decomposition of intermediates with a reduced volume penalty. Finally, a ring-closing metathesis reaction is discussed for which the utilization of a CSTR allows the removal of catalyst-poisoning ethylene formed during the reaction and keeps the substrate concentration low to increase the yield above that of a batch or plug-flow system.

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
