Binary systems of 1:2 ChCl:G
DES/water or glycerol/water
0–100% mole fraction (in
5% intervals) or 0.9 mole
fraction for MD
simulations
FTIR and Raman
spectroscopies and MD
simulations
Results analysis by a multivariate
method detected five species in the
DES-water mixture: pure water, DES,
DES-water association, glycerol, and
glycerol-water association. The
DES-water interactions dominate over
DES-DES interactions at 0.9 mole
fraction of water. Yet, DES was
identified as a highly stable distinct
solvent from its constituents. MD
simulations pictured the mixture of
DES-water at 0.9 mole fraction of water
as three different regions: a similar
structure to that of pure DES, ChCl
solvated by water, and self-assembled
glycerol molecules (Fig. 1.8).
