Physical Solubility of Carbon Dioxide in Aqueous Alkanolamines via Nitrous Oxide Analogy

Van Krevelen coefficients for protonated monoethanolamine (MEA), diethanolamine (DEA), and methyldiethanolamine (MDEA), the carbamates of MEA and DEA, and the bicarbonate ion have been determined experimentally from measurements of the solubility of N sub(2)O at 25 degree C and atmospheric pressure...

Beschreibung
Zusammenfassung:	Van Krevelen coefficients for protonated monoethanolamine (MEA), diethanolamine (DEA), and methyldiethanolamine (MDEA), the carbamates of MEA and DEA, and the bicarbonate ion have been determined experimentally from measurements of the solubility of N sub(2)O at 25 degree C and atmospheric pressure in aqueous solutions of these ions. Measured values differ significantly from values recommended by others in the absence of experimental data. By analogy with N sub(2)O, the solubility of carbon dioxide in the same solutions can be estimated.
