Description

Application

Tetrabutylammonium bromide may be used in the molten state in the following processes:
  • Synthesis of (2S)-5-(3-phenyl-2-phthalimidylpropanoylamino)isophthalic acid.
  • Synthesis of alkyl-substituted pyrroles in the absence of catalyst and organic solvent.
  • Synthesis of dithioacetals from acetals by transthioacetalisation in a solvent free environment.
  • Synthesis of polyamides (PAs) by the polymerization of terephthalic acid and diisocyanates.
  • Catalyze the addition of thiols to conjugated alkenes.
  • Dehydrochlorination of poly(vinyl chloride).

General description

Tetrabutylammonium bromide is a quaternary ammonium compound that is widely used as a phase transfer catalyst. Absolute viscosities of its aqueous solutions have been measured at various temperatures (20,25 and 30°C). Various physical properties (activity coefficient up to saturation, conductance, density and solubility in water) of TMABr have been evaluated.
