Comparative study of various amines for the reversible absorption capacity of carbon dioxide

Aqueous solution of α-amino amides has been found to exhibit good reversible absorption capacity of carbon dioxide compared to amino alcohols when carbon dioxide is absorbed under 1 atm. However, the absorption capacity of α-amino amides is highly dependent on the partial pressure of carbon dioxide, the absorption capacity being considerably decreasing when carbon dioxide is absorbed under 0.1 atm.
