This investigation demonstrated that bicarbonate ions were selectively formed over carbamate in a CO2 absorption process using piperidine and piperazine derivatives based on 13CNMR. Piperidines with methyl or hydroxymethyl substituent at 2 position (PiP-Me and PiP-MeOH) and 2,5-dimethylpiperazine (DM-PiZ) generated the bicarbonate ions as main adducts in reaction with CO2. The absorptions of CO2 by those aqueous amines (PiP-Me and DM-PiZ) were faster than those of MEA (2-aminoethanol).
