General description

Dimethylammonium dimethylcarbamate (DIMCARB) is the carbamate salt of dimethylamine. It is widely used as solvent and extractant. It has been investigated as ionic liquid. DIMCARB is formed by the reaction of dimethylamine and carbon dioxide.

Application

Dimethylammonium dimethylcarbamate (DIMCARB) may be employed as an equivalent of dimethylamine, which on reaction with carboxylic acids affords N,N-dimethyl amides. It may be employed as ionic liquid for the synthesis of Cup-shaped calix[4]arenes bearing one or two ketocyanine fluorophore fragments at the wide rim of the macrocycle.
Ionic liquid primarily used as a solvent.
  • For synthesis of calixarene-based ketocyanine fluorophores
  • Distillation extraction of tannins from plant materials
  • Electrodeposition of silver or of lead on glassy carbon and mercury film electrodes
  • Synthesis of Ag and Au nanostructures
  • Reusable reaction medium for synthesis of monoarylidene cyclopentanones
