The opposite effect of water and N-methyl-2-pyrrolidone cosolvents on the nanostructural organization of ethylammoniumbutanoate ionic liquid: a small and wide angle X-ray scattering and molecular dynamics simulations study
Two series of mixtures of ethylammoniumbutanoate (EAB, [N0 0 0 2][C3CO2]) in water and N-methyl-2-pyrrolidone (NMP) have been prepared at different molar fractions to assess the effect of these two polar solvents on the nanostructural order present in [N0 0 0 2][C3CO2]. The small- and wide-angle X-ray scattering (SWAXS) pattern of the liquid in neat state shows a prepeak at Q = 0.513 Å-1, which is associated with the aggregation of nonpolar alkyl chains of both cations and anions.
