Continuous Production of an API Suspension (ZS-9) under Oscillatory Flow at Intensified Temperature and Pressure
Bibliographic record
Abstract
A baffleless oscillatory flow coil reactor is implemented for the continuous production of a sodium zirconium cyclosilicate (SZC) species (ZS-9) suspension at elevated temperature and pressure. Development of the process and the resulting effects on product quality are outlined, including both mechanical changes to the reaction system itself and parametric tests of the operating conditions. The reaction apparatus proceeded through several iterations, where physical changes upstream of the crystallization coil from a simple T-junction mixing point to the final system containing a prefilled seeding loop led to significant improvements in product quality. The effects of system temperatures, fluid space times, and oscillation intensity are then outlined, leading to final operating conditions consisting of a 1 h crystallization fluid space time at 245 °C and up to 75 bar, a 173 °C seeding temperature, and a velocity ratio ( Re o / Re n ) ratio of 175 and a ZS-9 production rate of 40 g/h.

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.
