Synthesis and Characterization of Acrylated Epoxidized Flaxseed Oil for Biopolymeric Applications
Bibliographic record
Abstract
Abstract In this study acrylated epoxidized flaxseed oil was synthesized and then characterized by spectroscopic techniques. Triglycerides are the main constituents of flaxseed oil and the carbon-carbon double bond is the reaction site for epoxidation. Flaxseed oil was epoxidized by adding formic acid and hydrogen peroxide. Acrylic acid was then added to produce acrylated epoxidized flaxseed oil (AEFO). The change in the structure of the fatty acids chain after the epoxidation and acrylation reactions was measured and characterized by Hydrogen nuclear magnetic resonance spectroscopy ( 1 H NMR) and Fourier transform infrared spectroscopy (FTIR). The FTIR spectra of epoxidized flaxseed oil and flaxseed oil shows the disappearance of the =C–H (3012 cm −1 ) and C=C (1654 cm −1 ) peaks. The FTIR spectra confirmed the formation of AEFO since the presence of hydroxyl group (–OH) was shown by the peak at 3455 cm −1 and the acrylate group (–CH=CH 2 ), which was indicated by the peaks at 1406, 984 and 812 cm −1 . The changes in peaks of the 1 H NMR spectra also confirmed the formation of AEFO. The number of acrylate groups/molecule of triglyceride was found to be 2.6 from 1 H NMR spectra.

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.
