Equilibrium Conditions for TBAB and TBAC Semiclathrates of Xenon and Argon
Bibliographic record
Abstract
A constant-volume reactor was used for measuring the solid–vapor–liquid equilibrium conditions of semiclathrates formed in aqueous solutions of tetra- n -butyl ammonium bromide (TBAB) and tetra- n -butyl ammonium chloride (TBAC). The TBAB and TBAC semiclathrates were formed from pure Ar and pure Xe. The experimental temperatures ranged from (284 to 303) K, the experimental pressures ranged from (266 to 6114) kPa, the concentration of TBAB ranged from w TBAB = (0.05 to 0.20), and the concentration of TBAC ranged from w TBAC = (0.05 to 0.20). As expected, at a given temperature, the pressure required to form TBAB and TBAC semiclathrates with argon and with xenon was much lower than the pressure that was required to form pure gas hydrates. From the equilibrium data, the enthalpy of formation was estimated to be between (133 and 188) kJ·mol –1 for semiclathrates formed from argon and (55 and 127) kJ·mol –1 for semiclathrates formed from xenon.

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.
