  New ionic liquids (ILs) are continuously introduced involving an increasing
number of organic and inorganic ions. Amino acid based ILs (AAILs) represent a
specific interest due to their natural origin and, allegedly, low cost. We
apply our recently developed force field for imidazolium-based AAILs to
investigate structure properties in their aqueous solutions via molecular
dynamics (MD) simulations. By reporting cluster analysis, radial distribution
functions and spatial distribution functions, we argue that AAIL ions are well
dispersed in the aqueous media, irrespective of the AAIL content. Aqueous
solutions of AAILs exhibit desirable properties as solvents for chemical
engineering. The AAILs in relatively dilute aqueous solutions (10 mol% AAIL)
exist as ion pairs, while more concentrated solutions feature certain amount of
larger ionic aggregates.
