A novel type of dual-functionalized pyridinium-based ionic liquids (ILs) with acidic protons and hydroxyl groups, were designed and synthesized for ammonia (NH3) absorption. The NH3 absorption isotherms in dualfunctionalized pyridinium-based ILs at temperatures from 303.15 to 343.15 K and pressures up to 600 kPa were computed using gas-liquid equilibrium method. It revealed that 4-pyridinemethanol bis (trifluoromethane)sulfonamide [4-MeOHPy][NTf2] showed the maximum NH3 solubility of 3.43 mol NH3/mol IL at 313.15 K and atm. pressure, surpassing any nonmetallic ILs previously reported. Furthermore, the characteristics of isotherms under low pressures behaved an obvious chem. reaction between ILs and NH3, and all exptl. solubilities were regulated by a reaction equilibrium thermodn. model (RETM). The thermodn. properties were further obtained to better understand the NH3 absorption process. The results indicated that this model endorses the 1:1 (NH3-IL) mole ratio of chem. reaction mechanism and the reaction enthalpy is main driving force of NH3 absorption in ILs.
