It has no boiling point.


The melting point of the deep eutectic solvent of choline chloride and urea is 12 °C.

Thus, the DES is an ionic liquid at room temperature.

One of its most remarkable properties is that its vapour pressure is almost zero.

When you heat the liquid, the compounds start to decompose at about 200 °C, which is long before you would reach the boiling point of an ionic liquid.
