^aw_i denotes mass fraction of component i in the stock solution prior to absorption of CO₂, b_i denotes the corresponding molality with water as the solvent, m₀ = 1 mol kg^–1, T_min and T_max are the minimum and maximum experimental temperatures, and α/α_sat is the approximate degree of CO₂ saturation at the solution preparation temperature of (294 ± 1) K. Component 2 is MEA while component 3 is identified in the table.
