“…For the glucose-, fructose-, and sucrose-based NADES, the ChCl C-O vibration near 1005 cm −1 disappears in the NADES or has moved to a slightly higher wavenumber. For the xylosebased NADES, the C-C vibration at 1135 cm −1 for both ChCl and xylose appears to be shifted to a slightly higher wavenumber [46,47].…”

Phase behavior, density, viscosity, conductivity, pH, and surface tension were measured, and FTIR was performed for a series of mixtures of sugar (glucose, fructose, xylose, and sucrose), water, and choline chloride (ChCl) at specific molar ratios. These mixtures, called sugar-based natural deep eutectic solvents (NADESs), were investigated as a function of temperature. Contact angle measurements indicated that NADES exhibited slightly lower wettability but higher surface tension than water. Temperature was found to greatly impact density, viscosity, and conductivity. The optimum water molar ratio for lower viscosity was found at ratios higher than those reported in the literature, indicating that the NADES investigated may have industrial process applications.
