| titleOfInvention | Methods for liquid extraction of rare earth metals using ionic liquids |
| abstract | A method for extracting a rare earth element from a rare earth-containing substance, the method comprising mixing the rare earth-containing substance with a protic ionic liquid, such as: n nwherein R 1 is selected from hydrogen atom and hydrocarbon groups containing 1 to 6 carbon atoms; R 2 and R 3 are independently selected from hydrocarbon groups containing 1 to 12 carbon atoms; and X − is an anionic species; to produce a composition of the formula (RE)(amide) y X z at least partially dissolved in the protic ionic liquid, wherein RE is at least one rare earth element having an atomic number selected from 39, 57-71, and 90-103; y is 2-6; z is a number that charge balances the total positive charge of RE; and the amide is the conjugate base of the cationic portion of the protic ionic liquid of Formula (1) and has the following formula: |
