Bibliographic record
Abstract
Solid–liquid equilibrium (SLE) and solution density data for the (Na 2 SO 4 + H 2 NCH 2 CH 2 SO 3 H + H 2 O) system from (288.15 to 328.15) K were measured by use of the method of isothermal dissolution. From the experimental data, a set of polynomial equations were derived to calculate the solubility of taurine as a function of sodium sulfate mass fraction in the equilibrium solution, and two phase diagrams at (293.15 and 318.15) K were constructed. In general, the density of the equilibrium solution regularly increases with the sodium sulfate concentration. Furthermore, at low temperatures the equilibrium solid phase is Na 2 SO 4 ·10H 2 O, whereas at high temperatures the equilibrium solid phase is Na 2 SO 4 . All of these data will provide a better understanding of the separation of taurine from Na 2 SO 4 aqueous solutions through crystallization.

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; both teacher heads agree on what is shown here.
