Amine-based CO2 phase change absorbents (CPCAs) have received considerable attention for their potential energy efficiency. This study presents an aminoethylethanolamine (AEEA)-based CPCA using n-butanol (n-BuOH) as a separator efficient capture. The experimental results demonstrate that the obtained of AEEA/n-BuOH/H2O exhibited 44.0% higher cyclic capacity and 24.9% lower regeneration consumption compared to AEEA/H2O. In addition, quantitative NMR analysis species distribution in both upper phases revealed effective separation between products. Specifically, n-BuOH was present rich at only 3.2%, with remainder consisting Moreover, mechanism elucidated by studying difference dipole moments substances during Overall, n-BuOH-regulated AEEA-based shows promise candidate practical capture applications.
