Abstract:

This work is focused on the possible capture of nitrous oxide and more precisely protoxide using ionic liquids (ILs). ILs are gaining special attention since the efficiency of many processes can be enhanced by the judicious manipulation of their properties. The absorption of greenhouse gases can be enhanced by the basic character of the IL. In this work, these characteristics are evaluated through the study of the gas-liquid equilibrium of five imidazolium-based ILs: 1-butyl-3-methylimidazolium tetrafluoroborate ([BMIM][BF(4)]), 1-butyl-3-methylimidazolium thiocyanate ([BMIM][SCN]), 1,3-dimethylimidazolium methylphosphonate ([DMIM][MP]), 1,3-diethoxyimidazolium bis(trifluoromethylsulfonyl)imide ([(ETO)(2)IM][Tf(2)N]), and 1,3-dihydroxyimidazolium bis(trifluoromethylsulfonyl)imide ([(OH)(2)IM][Tf(2)N]) with N(2)O at temperatures up to 373 K and pressures up to 300 bar. Experimental data indicate that 44-105 g of N(2)O can be absorbed per kilograms of IL.
