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.
Application
Tetrabutylammonium bromide (TBAB) 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).
