Novel Approaches for Synthesis of Polyols from Soy Oils
Bibliographic record
Abstract
A method for synthesis of polyol from soybean oils has been developed using a two-step continuous route. The method involved epoxidation of soy oils and subsequent hydroxylation to produce polyols. The epoxidation was carried out using biphasic catalytic system (Na2WO4 / H2WO4) with 50 % hydrogen peroxide. The major advantages of this approach are that; the use of biphasic system allows easy separation of the products, does not require any chlorinated solvent (more environment-friendly), can be conducted at room temperature and requires relatively lower catalyst load. The functional groups of soy-polyol were identified using FTIR and NMR spectroscopy. This confirmed complete disappearance of the signature of the C=C double bonds, formation of the epoxy linkage following the epoxidation process, its further disappearance and incorporation of hydroxyl groups after the hydroxylation process. The hydroxyl number, hydroxyl functionality, acid value, iodine value and viscosity of the synthesized polyols were also determined.

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.
