제목 Selective Bicarbonate Formation in CO2 Absorption Process Based Secondary Cyclic Amines
초록 We demonstrate that secondary cyclic amine(PiP; piperidine and PiZ; piperazine) derivatives with substituents at 2- or 5-position afforded carbamate ions as main adduct in the CO2 absorption process. From the results of 13C-NMR, the piperidines with methyl or hydorxylmethyl substitutent at2 position(PiP-Me, PiP-MeOH) and 2,5-dimethylpiperazine(DM-PiZ) represented that the bicarbonate ions were selectively generated with carbamate ions as minor. The initial absorption rates of amines for CO2 capturing were shown a tendency of PiP>PiP-Me>DM-PiZ>MEA>PiP-MeOH.
