CO2 与位阻胺 2-氨基-2-甲基-1-丙醇 (AMP) 之间反应的反应速率常数是通过测量水性和非水性（1-丙醇）AMP 溶液吸收 CO2 的速率来确定的。具有水平液-气界面的搅拌池反应器用于吸收研究。发现两性离子机制适合模拟 AMP 水溶液和 1-丙醇-AMP 溶剂中 CO2 的吸收。对于这两种情况，胺的偏序都大于 1。 AMP 水溶液的动力学参数是在 15 至 45 摄氏度的温度和 0.25-3.5 kmol m(-3) 的 AMP 浓度范围内获得的。
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.
