Promoted isomerization of aldoses to ketoses in subcritical aqueous acetonitrile
Bibliographic record
Abstract
Isomerizations of d‐glucose, d‐mannose, d‐fructose, d‐galactose, d‐xylose, d‐ribose, cellobiose, maltose, lactose, and melibiose were investigated in subcritical aqueous acetonitrile. d‐Glucose and d‐mannose were preferred to be isomerized to d‐fructose, while d‐fructose mainly underwent decomposition rather than isomerization. Effects of acetonitrile concentration and temperature on saccharide isomerization were investigated using glucose as a substrate. The conversion of d‐glucose and yield of d‐fructose were improved with increasing acetonitrile concentration at 180 to 200 °C. In attempts to produce rare ketoses simply, d‐tagatose, d‐xylulose, d‐ribulose, cellobiulose, maltulose, lactulose, and melibiulose were successfully produced in high yields and selectivities by treating their corresponding aldoses with subcritical aqueous acetonitrile.

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.
