Protic ionic liquid ethanolamine thiocyanate with multiple sites for highly efficient NH3 uptake and NH3/CO2 separation

Development of high-efficient absorbents for ammonia (NH3) to improve the quality of atmosphere and ecological environment has gained interest among scholars. Ionic liquids (ILs) with unique properties have been reported as potential solvents for NH3 uptake to avoid many problems troubling the traditional NH3 capture technology. In this study, six protic ethanolamine-based ILs (PILs) were synthesized for efficient and reversible NH3 uptake, with...
