Chemical dual-site capture of NH3 by unprecedentedly low-viscosity deep eutectic solvents

It is unprecedentedly found that ethylamine hydrochloride (EaCl) and phenol (PhOH) can form a new type of deep eutectic solvent (DES) with quite low viscosity. The strong hydrogen-bond donating abilities of EaCl and PhOH provide two active sites for robust interaction with NH3. Thus, the capacities...

Summary:It is unprecedentedly found that ethylamine hydrochloride (EaCl) and phenol (PhOH) can form a new type of deep eutectic solvent (DES) with quite low viscosity. The strong hydrogen-bond donating abilities of EaCl and PhOH provide two active sites for robust interaction with NH3. Thus, the capacities of EaCl + PhOH DESs for NH3 absorption are notably high even at low pressures.
