dc.description.abstract | The pathways for the CO2 absorption and desorption in an aqueous solution of a heavily hindered alkanolamine, 2-(t-butylamino)ethanol (TBAE) were elucidated by X-ray crystallographic and C-13 NMR spectroscopic analysis. In the early stage of the CO2 absorption, the formation of carbonate species ([TBAEH](2)CO3) was predominant, along with the generation of small amounts of zwitterionic species. With the progress of the absorption, the carbonate species was rapidly transformed into bicarbonate species ([TBAEH]HCO3), and the amounts of the zwitterionic species increased gradually. During desorption at elevated temperature in the absence of CO2, [TBAEH]HCO3 was found to transform into [TBAEH](2)CO3, where CO32- strongly interacts with two [TBAEH](+) via hydrogen bondings. | - |
