Abstract
[79-10-7] C3H4O2 (MW 72.06) (acylating agent, electrophile in 1,4-addition reactions, dienophile in Diels–Alder reactions) Alternate Name: propenoic Acid. Physical Data: mp −13 °C; bp 139 °C; d 1.051 g cm−3; nD 1.4224. Solubility: miscible with water, alcohol, ether, acetone, and benzene. Form Supplied in: colorless liquid (stabilized with 200 ppm hydroquinone monomethyl ether); widely available. Purification: can be purified by steam distillation, or vacuum distillation through a column packed with copper gauze to inhibit polymerization (this treatment also removes inhibitors such as methylene blue that may be present). Azeotropic removal of the water with benzene converts wet acrylic acid into the anhydrous material. Handling, Storage, and Precautions: polymerization occurs readily in the presence of oxygen. The liquid is toxic, corrosive, has an acrid odor, and fumes. Use in a fume hood.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.
How this classification was reachedexpand
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.
