Abstract

The synthesis of a small library of nitrogen-based CO 2- switchable cationic surfactants with different head groups is described. These switchable surfactants can be switched on by addition of CO 2 and switched off by the removal of CO 2. The structure of the switchable head group affects the surfactant s basicity, solubility, heat of protonation, rate and extent of switching, and ability to reversibly stabilize and demulsify oil-water emulsions
