Carboxyl-functionalized task-specific ionic liquids for solubilizing metal oxides.
Imidazolium, pyridinium, pyrrolidinium, piperidinium, morpholinium, and quaternary ammonium bis(trifluoromethylsulfonyl)imide salts were functionalized with a carboxyl group. These ionic liquids are useful for the selective dissolution of metal oxides and hydroxides. Although these hydrophobic ionic liquids are immiscible with water at room temperature, several of them form a single phase with ...
متن کاملSulfonic acid functionalized ionic liquids for dissolution of metal oxides and solvent extraction of metal ions.
New sulfonic acid functionalized ionic liquids (SAFILs) with bis(trifluoromethylsulfonyl)imide anions were synthesized. These ionic liquids are strong Brønsted acids and can solubilize metal oxides. Water-immiscible SAFILs were used as organic phases in solvent extraction studies.
متن کاملFast selective homogeneous extraction of UO22+ with carboxyl-functionalised task-specific ionic liquids
The carboxyl-functionalised task-specific ionic liquid of 1-carboxymethyl-3-methylimidazolium bis(trifluoromethyl-sulfonyl)imide ([HOOCmim][NTf2]) was used as solvent and extractant for UO22+ extraction from aqueous solution. A homogeneous phase of [HOOCmim][NTf2]-H2O system could be achieved at 75 °C, and 86.8 ± 4.8% of UO22+ was separated from the aqueous solution after vibrating for only 1 m...

متن کاملSynthesis and Sorption Analysis of Task-specific Fluorous Ionic Liquids
Six 1-alkyl-4-tridecafluorooctyl-1,2,4-triazolium triflimides 2a–f and 4-amino-1-tridecafluorooctyl-1,2,4-triazolium triflimide (4) were prepared from the respective iodides 1a–f (1a, 2a: n-propyl; 1b, 2b: n-butyl; 1c, 2c: n-hexyl; 1d, 2d: n-heptyl; 1e, 2e: n-octyl; 1f, 2f: n-decyl) and iodide 3 by ion metathesis. Compounds 2a and 4 are liquid at room temperature. Two liquid fluorous imidazoliu...
