Abstract

fetched live from OpenAlex

A new method for the preparation of peroxymonophosphoric acid (H 3 PO 5 ) has been developed. It utilizes a biphasic solution to moderate the vigorous reaction between phosphorous pentoxide (P 2 O 5 ) and hydrogen peroxide (H 2 O 2 ). P 2 O 5 is suspended in carbon tetrachloride (CCl 4 ), and concentrated H 2 O 2 is slowly added while being vigorously stirred at low temperature. Careful control of the reaction temperature through the slow addition of H 2 O 2 is critical. Using typical preparation conditions (P 2 O 5 :H 2 O 2 = 0.5:1, H 2 O 2 70 wt %, 2°C, 120–180 min), ~70% of the H 2 O 2 is effectively converted to H 3 PO 5 . Increasing the concentration of H 2 O 2 , as well as the mole ratio of P 2 O 5 :H 2 O 2 , leads to an even higher % conversion of H 2 O 2 to H 3 PO 5 . The addition of glacial acetic acid to the P 2 O 5 :H 2 O 2 suspension at the end of the 120–180 min reaction (P 2 O 5 :H 2 O 2 :CH 3 COOH = 0.5:1:0.3) leads to the formation of peracetic acid in addition to H 3 PO 5 , and to an overall increase in the conversion ratio of total peroxy acids based on H 2 O 2 (>95%).Key words: peroxymonophosphoric acid, synthesis, stability, conversion ratio.

Teacher imitation

Not 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.
