Consulate Temperature
Channel: Physical Chemistry
Date: 2021-02-02

The consulate temperature, or critical solution temperature, is the first temperature at which a pair of partially miscible solvents can show phase separation into immiscible liquids.

Depending on whether the solubility of one solvent in the other increases or decreases with rising temperature, the solution exhibits an upper or a lower consulate temperature. In some cases, there is both an upper and a lower consulate temperature.
