A solvent that reversibly converts from a hydrophobic liquid form to hydrophilic liquid form upon contact with water and a selected trigger, e.g., contact with CO2, is described. The hydrophilic liquid form is readily converted back to the hydrophobic liquid form and water. The hydrophobic liquid is an amidine or amine. The hydrophilic liquid form comprises an amidinium salt or an ammonium salt. Le solvant ci-décrit peut être converti de manière réversible pour passer d'une forme liquide hydrophobe à une forme liquide hydrophile par contact avec de l'eau et un déclencheur choisi, par exemple, par contact avec du CO2. La forme liquide hydrophile est facilement reconvertie en forme liquide hydrophobe et eau. Le liquide hydrophobe est une amidine ou une amine. La forme liquide hydrophile comprend un sel d'amidinium ou un sel d'ammonium.
