Green solvents from ionic liquids and deep eutectic solvents to natural deep eutectic solvents

open access: yesComptes Rendus. Chimie, 2018
Natural deep eutectic solvents (NADESs) are defined as mixtures of certain molar ratios of natural compounds such as sugars, organic acids, amino acids, and organic bases that are abundant in organisms. The melting points of these mixtures are considerably lower than those of their individual ingredients and far below ambient temperature.
