Abstract

fetched live from OpenAlex

New experimental data regarding the solubility of 5-chloro-4-hydroxy-3-methoxybenzaldehyde and 4-chloro-2-methoxyphenol in water were obtained in the temperature range 280 to 363 K. The solubilities were measured by means of two techniques, namely high-performance liquid chromatography (HPLC) and total organic carbon (TOC). Considering the sparingly soluble 5-chloro-4-hydroxy-3-methoxybenzaldehyde, the aqueous infinite dilution activity coefficients were also obtained over the same temperature range by measuring the aqueous solubilities and the organics' enthalpies of fusion. The values of the infinite dilution activity coefficients ranged from 120 to 350 with an average relative deviation of 11%. The solubility−temperature dependence for both organics was well represented by conventional Van't Hoff relationships.

Full frame distilled prediction

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.
