The pseudo-first-order rate constants (kOV) for the reactions between CO2 and diethanolamine have been studied using the stopped-flow technique in an aqueous solution at 293, 298, 303 and 313 K. The amine concentrations ranged from 167 to 500 mol·m-3. The overall reaction rate constant was found to increase with amine concentration and temperature. Both the zwitterion and termolecular mechanisms were applied to correlate the experimentally obtained rate constants. The values of SSE quality index showed a good agreement between the experimental data and the corresponding fit by the use of both mechanisms.

W pracy przedstawiono wyniki badań kinetycznych reakcji CO2 w wodnych roztworach dietanoloaminy. Badania przeprowadzono z zastosowaniem techniki zatrzymanego przepływu w temperaturze 293, 298, 303 i 313 K, w zakresie stężeń aminy od 167 do 500 mol·m-3. Stwierdzono wzrost wartości stałej szybkości reakcji pseudopierwszego rzędu wraz ze wzrostem stężenia aminy oraz temperatury. Dane eksperymentalne zostały opisane za pomocą zależności kinetycznych wynikających z mechanizmu jonu dwubiegunowego oraz reakcji trójmolekularnej. Parametry kinetyczne dla obu mechanizmów wyznaczono w oparciu o minimalizację przyjętego wskaźnika jakości (SSE). Wartości tego wskaźnika wykazały dobrą zgodność pomiędzy danymi doświadczalnymi i odpowiednimi dopasowaniami z użyciem obu modeli kinetycznych.
