Abstract

fetched live from OpenAlex

Abstract The sustainable step‐growth polymerization of glycerol is monitored in‐line and off‐line using an ATR‐FTIR spectroscopic probe. The concentration of hydroxyl groups is monitored to provide real‐time conversion data using a univariate method. Traditional off‐line techniques, i.e., hydroxyl value calculation and water production monitoring, are compared to in‐line and off‐line ATR‐FTIR spectroscopy. Fouling of the probe is observed beyond 42 mol% conversion of hydroxyl groups. No statistically significant differences are found between the conversion data from off‐line/in‐line ATR‐FTIR and two other methods at a 95% confidence level prior to fouling, and this confirms that ATR‐FTIR is a reliable tool for monitoring conversion for production of oligoglycerols from a renewable feedstock. magnified image

Full frame distilled prediction

Teacher imitation

Not 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.
