“Figure 6 shows the vapor–liquid equilibrium results obtained for solutions containing mixtures of different diluents and 10 wt % of N,N-diethylethanolamine, at both 40 and 80 °C. These data, together with its uncertainties, can also be found in the Supporting Information.”

“This time, it is possible to draw a direct comparison between the water-lean solvents and H2O–DEEA at both 40 and 80 °C, as neither volatility issues nor phase separation was observed in the aqueous solution. Naturally, this lower volatility is a direct consequence of the alcohol group of DEEA, which is why alkanolamines are favored over organic amines for CO2 absorption purposes in the first place. (53)“
