摘要：
Qualitative and quantitative C-13 NMR studies were performed on 30 wt % aqueous solution of 2-amino-2-methyl-1-propanol (AMP) with different amount of CO2 at 25 degrees C. The results suggested that the main species in this system are: AMP/AMPH(+), AMPCO(2)(-) and HCO3-/CO32-. The carbamate was observed at low loading and the carbamate stability constant was calculated based only on the experimental species concentration from NMR analysis. Based on the liquid phase speciation from NMR, the carbamate stability constant on mol fraction basis was found to be about 0.47 at 25 degrees C. (C) 2011 Published by Elsevier Ltd.
