Table . Hydrogen bond donors that formed liquids at all molar ratios HBD a HBA (liquid in all ratios) HBD a HBA (liquid in all ratios) (S)/(R)-2acetoxypropionic acid this screening cannot be used to distinguish between DES and simple eutectic mixtures, or even understand how environmental water may play a role in liquid formation. In order to better understand the chiral liquids/solvents prepared by the screening process, it is important to measure the water content, thermal and physical properties. Since it is beyond the scope of this manuscript to document the properties of all of the successful liquid mixtures, a subset (< 100) were prepared in larger quantities to characterize their properties, and results from 20 of these mixtures are presented in this manuscript. A table of the measured water content along with the component mole fraction for these mixtures is included in the supporting information. Measured water content of most of the samples varied from 0.2-6.0 % (w/w), which corresponds to water mole fractions between 0.02-0.42. The samples with the highest water content have water as the largest component by moles in the mixture. However, none of these mixtures would be classified as an aqueous solution, and the mole fractions are within a range that has been characterized as "water in DES". It is probably most accurate to characterize the chiral mixtures in this study as ternary eutectic mixtures, composed of HBA, HBD, and water. The only way to classify a mixture as a DES at the eutectic point is to measure a complete solid-liquid equilibrium curve, 1 which is impractical for the number of liquid mixtures in this study. However, a measure of the melting point depression upon mixing can provide a method to classify if the mixture is a simple eutectic or a DES. When the melting point depression is larger than what would be observed in an ideal mixture, the mixture can be classified as a DES.
