Vapour–liquid equilibrium of CO2 in aqueous solutions of N-methyl-2-ethanolamine



The equilibrium solubility of CO2 into aqueous solution of sterically hindered N-methyl-2-ethanolamine or methyl amino ethanol (MAE) was investigated in the temperature range of 303.1–323.1 K and total CO2 pressure in the range of 1–350 kPa. The N-methyl-2-ethanolamine aqueous solutions studied were 0.968, 1.574, 2.240 and 3.125 mol kg−1 of solvent. © 2011 Canadian Society for Chemical Engineering
