  • bromide
  • 16. A polymeric, ionic imidazolium compound which can be obtained by a process according to claim 1, wherein less than 50 mol % of the amino compounds are compounds having a hydroxyl group in the β position relative to the primary amino group and the anionic counterion to the cationic polymer is not bromide.

  • The presence of ionic liquids with the chemical structure of 1-alkyl-3-methyl imidazolium bromide in wastewater did not deteriorate biological wastewater treatment processes if their concentration was not higher than 5 mg l −1 . (environmental-expert.com)
  • An imidazolium salt was grafted to cellulose nanocrystals (also called nanowhiskers) using copper(I) catalysed azide-alkyne cycloaddition and the bromide anion was successfully exchanged for bistriflimide and an anionic dye, providing the opportunity to synthesize a wide variety of ion exchange systems or catalysts using cellulose nanocrystals as a support medium.

  • ligand
  • Dans ce mémoire nous présentons la synthèse, la caractérisation et l'étude des propriétés catalytiques en milieu aqueux d'un ligand composé d'une unité -cyclodextrine native, d'une unité imidazolium et d'une chaine alkyle à 12 carbones. (umontreal.ca)
  • La fonctionnalisation de la face primaire de la -cyclodextrine par un noyau alkyl-imidazolium, précurseur de ligand de type carbène N-hétérocyclique, a permis le développement d'un système catalytique vert et hautement recyclable. (umontreal.ca)
  • Synthesis
  • An imidazolium-based ionic liquid (IL) functionalized zinc porphyrin catalyst was successfully synthesized for the first time, and was employed as an efficient catalyst for CO 2 transformation including both the chemoselective synthesis of cyclic carbonates from various epoxides and the regioselective synthesis of 5-aryl-2-oxazolidinones from N-substituted aziridines.

  • Structure
  • The occupied and unoccupied electronic structure of imidazole (C 3 N 2 H 4 ) and imidazolium (C 3 N 2 H 5 + ) in aqueous solutions is studied by X-ray emission spectroscopy (XES) and resonant inelastic soft X-ray scattering (RIXS). (rsc.org)
  • effect
  • An electrostatic attraction strategy based on main-chain imidazolium-based ionic polymer (ImIP) has been presented to suppress the shuttle effect of polysulfides in lithium-sulfur batteries. (rsc.org)
