Task-specific Ionic liquids for the solvent extraction of Molybdenum (VI) from aqueous solutions
(2017)
Molybdenum, Mo(VI), is recovered from leach liquors of molybdenite concentrates
by mean of solvent extraction (SX) using bis(2-ethylhexyl)phosphoric acid
(D2EHPA) as the extractant and kerosene as the diluent. However, ...
Task-specific ionic liquids: Applications in sample preparation and the chemistry behind their selectivity
(Elsevier, 2022-02)
Task-specific ionic liquids (TSILs) represent a sub-family of ionic liquids characterized by their high specificity towards a target analyte or group of analytes. This characteristic has made them valuable tools for sample ...
Significant effects of the anion on the catalytic behaviour of sulfonic acid-functionalized ionic liquids in transesterification reactions – A combined electrochemical/catalytic study
(Elsevier, 2021-08)
This work studies the strong influence of the counterion on the performance of ionic liquids (ILs) with sulfonic acid-functionalized butyl-imidazolic bases as homogeneous acid catalysts. Through a voltammetric analysis, ...
Insights on the catalytic behaviour of sulfonic acid-functionalized ionic liquids (ILs) in transesterification reactions - voltammetric characterization of sulfonic task-specific ILs with bisulfate anions
(Royal Society of Chemistry, 2021-01)
This work shows for the first time the link between the amount of free sulfuric acid (as detected by cyclic voltammetry) and the activity of sulfonic-acid-functionalized ionic liquids (ILs) as acid catalysts for a ...
Piperidine-appended imidazolium ionic liquids as task-specific catalysts: computational study, synthesis, and multinuclear NMR
(John Wiley & Sons Ltd, 2016-07-23)
Imidazolium ionic liquids (IMILs) with a piperidine moiety appended via variable length methylene spacers (with n = 1–4) were studied computationally to assess their potential to act as internal base for N-heterocyclic ...
Task-specific ionic liquid incorporating anionic heteropolyacid-catalyzed Hantzsch and Mannich multicomponent reactions. Ionic liquid effect probed by ESI-MS(/MS)
