0–100 wt%
MD simulations
Slight changes in hydrogen bond
numbers and radial distribution
functions were observed at a water
content lower than 5 wt%, while the
microscopic structure of both DES is
massively affected between 5 and
40 wt% of water. Above 40 wt%, both
DES lose their intermolecular structure
due to dissolution in water and thus the
studied parameters barely change.
Besides, the structure of DES-water is
not affected by the temperature.

2.5–60 wt%
NMR
The diffusion coefficients of the
mixture’s components revealed two
well-differentiated behaviors, at a
cross-over composition of 72 wt% DES,
as the water content varied. This was
explained by the predominance of the
“water-in-DES” system above 72 wt%
DES and a prevalence of the “DES-inwater” system below that same
composition.
