چکیده انگلیسی
The solubility of CO2 was measured in aqueous solutions of 2-(isopropylamino)ethanol (IPAE) and 2-(propylamino)ethanol (PAE) at 313Â K, 373Â K and 393Â K and CO2 partial pressures ranging from 5Â kPa to 0.2Â MPa. With different CO2 loadings, speciation analyses were conducted by accurate quantitative 13C nuclear magnetic resonance spectroscopy using inverse-gated decoupling. IPAE had a larger capacity for CO2 than PAE because of the dominant formation of bicarbonate rather than carbamate. However, a significant amount of carbamate was also observed with low CO2 loadings in the IPAE solutions. The results for these secondary amine solutions were compared with those of the primary amines monoethanolamine and 5-aminopentanol.
