摘要：
The enthalpies of absorption and solubility at T=298.15 K of carbon dioxide in aqueous solutions of bis-(3-dimethylaminopropyl)amine (CAS RN: [6711-48-4]) are reported in this paper. It was observed that the saturation loading of the CO2 is alpha =2.9 mol CO2/mol TMBPA, which is close to the theoretical value, alpha (0)=3 mol CO2/mol TMBPA. The molar heat of absorption of CO2 is independent of the polyamine concentration of the solutions and the amount of CO2 absorbed and was calculated to be Delta H-abs(m)=-44 (+/-2) kJ mol(-1) CO2.
