Synthesis, Characterization and Application of O, O-diethyl Acrylamide Phosphate
Bibliographic record
Abstract
Taking acrylamide and diethyl chlorophosphate as the reactants, we synthesized a sort of new intumescent flame retardant(IFR) containing phosphorus and nitrogen, O,O-diethyl acrylamide phosphonate. The structure of the title compoundcould be characterized by FTIR, 1H NMR and MS. The results show that the structure of the synthesized compound isconsistent with the expected structure. The yield of the title compound is 75% under the conditions that the molar ratiobetween acid-binding agents of triethylamine and acrylamide is 1:1 and the mass fraction of the catalys CuCl is 1% ofacrylamide. The optimal reaction temperature range is from 20 centi degree to 30 centi degree. The limiting oxygen index (LOI) value canreach 26.7% when the mass fraction of the title compound in the copolymer is 20%. The scanning electron microscopy(SEM) photos of the fired residue of the flame retarded copolymer show that the surface of the fired residue presentsfoam-like structure, and the cross section presents cellular structure, which indicate that the title compound is theintumescent flame retardant.

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.
