A study towards the kinetics of carbon dioxide (CO2) absorption into a novel aqueous solution of bis(3-aminopropyle)amine (APA) was carried out at 303, 308, 313 and 323 K over a concentration range of 0.1–0.5 kmol m−3 and different CO2 partial pressure. The reaction mechanism of CO2 with primary and secondary amines (zwitterionic mechanism) is described and based on this, experimentally obtained kinetic data are interpreted. A qualitative nuclear magnetic resonance [NMR (1D and 2D)] spectroscopy method has been applied to develop the reaction scheme for novel aqueous APA with CO2. The kinetic rate parameters were investigated according to the pseudo-first-order condition. The values of second-order rate constant, k2-APA and reaction rate with CO2 reported in this study were higher than piperazine (PZ), 2-(1-piperazinl)-ethylamine (PZEA), etc. Furthermore, enhancement factor increases significantly in comparison to aqueous MDEA solutions when the APA concentrations in the blends with MDEA varied from 0 to 0.5 kmol m−3.
