Experimental and modelling liquid–liquid equilibrium for the system 2-ethyl-1-hexanol + glycerol
Bibliographic record
Abstract
This work presents experimental data on liquid–liquid equilibrium (LLE) for the system 2-ethyl-1-hexanol + glycerin. Equilibrium data were obtained through “cloud point” method, at temperatures of 298.15 K, 313.15 K, 333.15 K, 368.15 K, 383.15 K, 403.15 K, and 433.1 K. For the experimental data, a UNIQUAC model was used to describe the phase’s equilibrium performance. Posteriorly, a phase split stability test was done to validate the parameters found in this model. The system presented “upper critical solution temperature” (UCST), and the parameters of the UNIQUAC model were satisfactorily adjusted (1.27% standard deviation). The stability phase test (phase split) proved the validation of the tested model.
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.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
