چکیده

The utilization of pure ionic liquids (ILs), as environmentally green and soft chemical solvents, is restricted in the CO2 capture industry due to their high viscosity and fair conductivity. In this paper, the novel comprehensive models were developed for accurate estimation of density, dynamic viscosity, surface tension, and electrical conductivity of a novel protic amino acid-functionalized IL, namely monoethanolamine glycinate, [MEA][GLY], in the temperature range of 303.15–323.15 K at two different intervals of water content (5–20 wt%, and 25–100 wt%). The results of the suggested models revealed that the density, viscosity, and surface tension of [MEA][GLY] decline substantially with rising temperature, while the electrical conductivity presents an adverse trend. Additionally, the impact of varying the concentration on the density and viscosity of the IL solution is more significant than the solution temperature, particularly at high concentrations of the IL. Moreover, a second-order polynomial equation was suggested to depict the equilibrium pressure dependence of CO2 loading capacity of aqueous [MEA][GLY] in IL, at various equilibrium pressures of 1–7 bar.
