  • ANIONIC SWITCHABLE HYDROPHILICITY SOLVENTS
    Publication number: 20230356114
    Abstract: Anionic switchable hydrophilicity solvents (ASHS) that can be reversibly converted between hydrophobic and hydrophilic forms are described. The ASHS comprise a carboxylic acid, a water-soluble base, water, and addition and removal of an acidic gas (CO2) effects the conversion between the hydrophobic and hydrophilic forms. A system and method for forming the ASHS are described, as well as applications utilizing the ASHS, including a method for separating a selected substance from a mixture, a method of removing gas from polymeric foam, and a method of extracting a hydrophobic material from a solid that is at least partially coated by the hydrophobic material.
