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).
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.
