| 제목 | Structural study of CO2 Absorption and Desorption in an Aqueous Solution of Heavily Hindered Alkanolamine. |
| 초록 | In the early stage of the CO2 absorption in an aqueous solution of a heavily hindered alkanolamine, 2-(t-butylamino)ethanol (TBAE), the formation of carbonate species ([TBAEH]2CO3) was predominant, along with the generation of small amounts of zwitterionic species. As the absorption progresses, 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]2CO3, where CO32− strongly interacts with two [TBAEH]+ via hydrogen bondings. X-ray crystallographic and 13C NMR spectroscopic analysis were used for this study. |
