Application

1-Butyl-2,3-dimethylimidazolium chloride can be used:
  • As a solvent in the chemical modification of polysaccharide cellulose.
  • As a model ionic liquid in the conversion of a monosaccharide like fructose into 5-hydroxymethylfurfural using H2SO4.
  • To prepare 1-butyl-2,3-dimethylimidazolium dicarba-7,8-nidoundecaborate by reacting with caesium dicarba-7,8-nido-undecaborate.
  • To prepare mesoporous ZnAl2O4 nanomaterials, which are used as catalysts or catalyst supports.

Although supertetrahedral Tn sulfide clusters (n=2-6) have been extensively explored, the synthesis of Tn selenide clusters with n>4 has not been achieved thus far. Reported here are ionic-liquid (IL)-assisted precursor route syntheses, characterizations, and the photocatalytic properties of six new

Multinary chalcogenido (semi)metalate salts exhibit finely tunable optical properties based on the combination of metal and chalcogenide ions in their polyanionic substructure. Here, we present the structural expansion of chalcogenido germanate(IV) or stannate(IV) architectures with SbIII , which clearly affects

Task-Specific Ionic Liquids

Functionalized imidazolium cations with thioether, urea, or thiourea derivatized side chains act as metal-ligating moieties, whereas the PF6– anions provide the desired water immiscibility.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
