Solid-liquid-vapour equilibrium conditions of tetra-iso-amyl ammonium bromide (TiAAB) semiclathrates formed from H2
Bibliographic record
Abstract
The tetra-iso-amyl ammonium bromide (TiAAB) is synthesized according to Menschutkin's reaction and the fundamental characterization of TiAAB is conducted using ESI mass spectrum and 13 C NMR spectra, respectively. Using an isochoric equilibrium cell the H 2 semi-clathrates were formed in the presence of three different TiAAB solutions; a 15 wt% solution, a 30 wt% solution, and a 45 wt% solution. Using TiAAB allows for the formation of H 2 semi-clathrates at much milder P-T conditions as compared to other quaternary ammonium salts such as TBAB, TBAN, TBPB, and TBAF. The mixed H 2 /TiAAB semi-clathrates were found to form over a narrow range of temperatures from 303 K to 304 K, and the pressure ranged from atmospheric pressure to above 4 MPa. The experimental results obtained in the current work contribute to developing a method to store hydrogen gas with mixed H 2 /TiAAB semi-clathrate.

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.
