抄録

In order to clarify the characteristic behavior of dissolved state of CO<SUB>2</SUB> in alkanolamine-H<SUB>2</SUB>O system five different kinds of alkanolamines were examined spectroscopically under the following conditions: 40 °C for 30 min to 120 min. NMR analysis indicated the presence of five chemical species such as carbamate ion, free amine, bicarbonate, carbonate, and protonated amine. Based on proton NMR, distribution of the respective species against molar loading of CO<SUB>2</SUB> was successfully evaluated.
