  • Fluorinated crown ethers and methods and systems for extraction of lithium using same
    Patent number: 11266926
    Abstract: The present disclosure provides fluorinated crown ethers. The fluorinated crown ethers have one or more pendant fluorinated groups (e.g., thioether groups with a terminal fluorinated group). The fluorinated crown ethers have desirable solubility in supercritical carbon dioxide. Also provided are methods and systems for removal of lithium (e.g., lithium ions) from aqueous samples using the fluorinated crown ethers coupled with lipophilic cation exchangers.
    Type: Grant
