Abstract
Experimentally found kinetic values (pseudo-first order rate constants) for the reaction of CO2 in different types of aqueous amines using stopped-flow technique were compared at 303.15 K. (Primary amines–1-amino-propanol(1-AP), 3-amino-propanol(3-AP),Ethylaminoethanol(EAE); Secondary amines–Ethylene diamine(EDA), 1, 3-diamino propane(DAP), 2-(amino ethyl)ethanol amine (AEEA); Cyclic amine–Piperazine; Poly amine–N-(2-aminoethyl)-1, 3-propane diamine). It was observed that polyamines and cyclic amines are having higher reaction rate than primary, and secondary amines. Therefore, the kinetics of the reaction of carbon dioxide with six cyclic amines)) in aqueous solutions has been studied at (298.15 to 313.15) K over a concentration range of (20to120) mol⋅m−3 using the stopped-flow technique.(Piperazine (PZ),1-methyl piperazine (1-MPZ),2-methyl piperazine (2-MPZ),1-ethyl piperazine (1-EPZ),N-(2-hydroxyethyl) piperazine (1-HEPZ) and 3-morpholino propyl amine (3-MOPA). PZ has the highest reaction rate and 1-MPZ has the lowest. The trend of reaction rates are given as (PZ>2-MPZ>1-EPZ>3-MOPA>HEPZ>1-MPZ). All the studied cyclic amines were found to have fractional reaction order with respect to amine varying from 0.9 to 2.43.Termolecular mechanism and Zwitterion-mechanism were used for calculating the rate parameters by fitting the experimental data.

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
