Out of phase : Ionic liquids (ILs) derived from amino acids exhibit phase separation with a lower critical solution temperature after mixing with water (see picture; upper phase water; lower phase IL). The phase‐separation temperature of these mixtures depends on the ion structure and water content, and is lowered by an increase in the hydrophobicity of the ionic liquid.
