Ternary hydrophobic deep eutectic solvents for carbon dioxide absorption
Highlights The synthesized H-DESs were characterized by FTIR and HNMR spectra. The physical properties of H-DESs were experimentally investigated at different temperatures. The hydrophobic nature of H-DESs was confirmed by a dye removal study. The synthesized H-DESs have shown high potential for CO2 absorption.
Abstract Ternary hydrophobic deep eutectic solvents (H-DESs) were synthesized using the binary mixture of fatty acids and tetrabutyl ammonium bromide. The formation of H-DES was confirmed by the phase diagram, FTIR and H NMR analyses. The critical properties of H-DESs were then determined using the modified “Lydersen-Joback-Reid” method. The viscosity and conductivity of H-DESs were experimentally calculated and modeled using the Arrhenius equation. Further, the hydrophobic nature of H-DESs was confirmed by the extractive dye removal from an aqueous solution. Finally, CO2 uptake of H-DESs was experimentally investigated using pressure drop method and the obtained results were correlated with the Peng-Robinson equation of state.
