چکیده	Recently, the application of functionalized ionic liquids in carbon dioxide (CO2) capture has received significant attention. In this research, the absorption kinetics of CO2 into the aqueous amino-acid-functionalized monoethanolamine glycinate ionic liquid in a stirred cell reactor was investigated. Amino acids are less volatile and have good resistance against oxidative degradation. Experiments were accomplished over a temperature range of 298–308 K and solution concentrations ranging from 0.5 to 2.5 M in the pseudo-first-order regime. The dimensionless Hatta number and infinite enhancement factor were calculated to check the fast pseudo-first-order reaction assumption. The reaction rate constant has been evaluated by recording the system pressure reduction rate over time. Increasing the IL concentration and temperature results in a significant increase in the reaction rate. The obtained kinetic constants have the same order of magnitude as those existing for primary amines.
