A solvent is described which reversibly converts a hydrophobic liquid form to a hydrophilic liquid form in contact with water and a selected actuator, v. gr., in contact with CO2. The hydrophilic liquid form easily converts 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. |
