ON THE ORIGIN OF PREFERRED BICARBONATE PRODUCTION FROM CARBON DIOXIDE (CO_2) CAPTURE IN AQUEOUS 2-AMINO-2-METHYL-1-PROPANOL (AMP)

摘要

Based on our calculation results, we attribute the preferentialrnformation of bicarbonate in CO_2 absorption into an aqueous AMPrnsolution largely to kinetic factors. As discussed above, the strongrninteraction between N (in AMP) and H (in H_2O) suppresses thernreaction with CO_2 and promotes the protonation reaction, while thernbicarbonate and carbamate reaction routes exhibit similarrnthermodynamic favorability. This study highlights that not onlyrnthermodynamic but also kinetic factors should be considered inrndescribing CO_2 capture by aqueous amines.
