Extraction and Separation of Rare Earth Metal Ions with DODGAA in Ionic liquids
In order to apply ionic liquids (ILs) to the separation of rare earth metals, liquid-liquid extraction of a series of rare earth elements into the ILs was investigated mainly using 1-octyl-3-methylimidazolium bis(trifluoromethyl sulfonyl) imide, [C8mim][Tf2N], with N,N-dioctyldiglycol amic acid (DODGAA) as the extractant. A higher selectivity was exhibited for the heavier rare earth elements as...
متن کاملIonic liquids with metal chelate anions.
A series of stable (air, water stable and with good thermal stability) and hydrophobic ionic liquids based upon metal chelate anions were synthesized, which were shown to be effective, mild, and easy to recycle catalysts at the same time stable solvents for the oxidation of cyclohexene.
متن کاملRare-earth metal hydroxylamide complexes.
The rare-earth metal hydroxylamide compound Y[N(SiHMe2)2]2[ONBn2][THF] (1) was prepared by the silylamide elimination pathway from the reaction of N,N-dibenzylhydroxylamine, Bn2NOH (Bn = CH2C6H5), with Y[N(SiHMe2)2]3[THF]2 and was characterised by multinuclear NMR spectroscopy and elemental analysis. The compounds [Cp2Y(ONBn2)]2 (2a) [Cp2Sm(ONBn2)]2 (2b) were obtained by the reactions of MCp3 (...
متن کاملThe acidity/basicity of metal-containing ionic liquids: insights from surface analysis and the Fukui function.
Metal-containing ionic liquids (ILs) have been recognized as potential solvents, catalysts, catalyst precursors and reagents for many organic processes. In this work, several quantum-chemical parameters, including the surface electrostatic potential (Vs,max and Vs,min), the lowest surface average local ionization energy (I̅s,min), and the electrostatic potential at the position of an atom (EPnuc...
