Title (EN) FLUORINATED CROWN ETHERS AND METHODS AND SYSTEMS FOR EXTRACTION OF LITHIUM USING SAME
(FR) ÉTHERS COURONNES FLUORÉS ET PROCÉDÉS ET SYSTÈMES D'EXTRACTION DE LITHIUM LES UTILISANT
Abstract:
(EN) 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.
(FR) La présente invention concerne des éthers couronnes fluorés. Les éthers couronnes fluorés ont un ou plusieurs groupes fluorés pendants (par exemple, des groupes thioéther avec un groupe terminal fluoré). Les éthers couronnes fluorés ont une solubilité souhaitable dans le dioxyde de carbone supercritique. L'invention concerne également des procédés et des systèmes d'élimination de lithium (par exemple, des ions lithium) dans des échantillons aqueux à l'aide des éthers couronnes fluorés couplés à des échangeurs cationiques lipophiles.
