Investigation of solid–liquid equilibrium of stevioside in different pure and binary mix solvents at various temperatures
Bibliographic record
Abstract
The solubility of stevioside (a natural sweetener) in 12 pure solvents (methanol, 1-propanol, 2-propanol, 1-buthanol, 2-buthanol, 1-pentanol, 2-pentanol, 2-ethoxyethanol, 2-propoxyethanol, 2-buthoxyethanol, water, and acetone) and in binary mixed solvents (2-ethoxyethanol + water) have been determined using high performance liquid chromatography (HPLC) method at temperatures ranging from 288.15 to 328.15 K and atmospheric pressure. From the experimental data, it was found that the solubility increased with the rising temperature in all selected solvents. The experimental data for the solubility of stevioside were correlated with Apelblat and non-random two-liquid (NRTL) models. It was found that the Apelblat model has the better quality in fitting the solubility data. Also, thermodynamic functions of dissolution, mixing and transfer process were calculated by the van’t Hoff equation. Furthermore, the crystal habits of stevioside in selected solvents were studied.

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; a candidate call from one teacher head, not a consensus.
