Is ethaline a deep eutectic solvent?
Vira Agieienko, Richard Buchner
Abstract
= 0.171) which is characterized by a melting point of 244 K. This temperature is only 16 K below the melting point of neat EG. Thus, neither from its particular composition nor from the observed melting-point depression of {ChCl + EG} mixtures can ethaline be considered a "deep eutectic solvent". Surprisingly, despite ChCl being an electrolyte dissolved in EG, the phase diagram is that of an ideal binary mixture.
