Abstract
Excess molar enthalpies (H E ) of the binary mixtures containing tetraethylene glycol dimethyl ether (TEGDME) or polyethylene glycol 350 monomethyl ether with a 1-alkanol (1-propanol, 1-butanol, or 1-pentanol) at 298.15 K and atmospheric pressure were measured using a Calvet microcalorimeter. All the H E experimental values were positive and increase as the 1-alkanol length increases. The results are discussed qualitatively in terms of molecular interactions. The UNIFAC and DISQUAC group contribution models have been used to compare the predicted and the experimental values.Key words: excess enthalpy, 1-alkanol, polyether, binary system.

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 it
