CO2 capture amines for which chemistry with bicarbonate (specifically carbamate formation) was investigated. 1 = 2-aminoethanol (ethanolamine, MEA); 2 = 1,2-diaminoethane (ethylenediamine, EN); 3 = piperazine (PZ); 4 = 2-amino-2-methyl-1-propanol (AMP); 5 = 2-amino-2-(hydroxymethyl)propane-1,3-diol (Tris); 6 = 2,2'-iminodiethanol (diethanolamine, DEA)
