摘要：

Reaction rate constants for the reaction between CO2 and the sterically hindered amine, 2-amino-2-methyl-1-propanol (AMP), were determined from measurements of the rate of absorption of CO2 into both aqueous and nonaqueous (1-propanol) AMP solutions. A stirred-cell reactor having a horizontal liquid-gas interface was used for the absorption studies. The zwitterion mechanism was found to be suitable for modelling the absorption of CO2 into the aqueous AMP solutions and into the 1-propanol-AMP solvent. The partial order in amine is greater than one for both cases. The kinetic parameters for aqueous AMP solutions were obtained for temperatures from 15 to 45 degrees C and over the concentration range of 0.25-3.5 kmol m(-3) of AMP.
