Description
- General description: Tetrabutylammonium bromide is a quaternary ammonium compound that is widely used as a phase transfer catalyst.[1] Absolute viscosities of its aqueous solutions have been measured at various temperatures (20,25 and 30°C).[2] Various physical properties (activity coefficient up to saturation, conductance, density and solubility in water) of TMABr have been evaluated.[3]
- Application: Tetrabutylammonium bromide may be used in the molten state in the following processes:Synthesis of (2S)-5-(3-phenyl-2-phthalimidylpropanoylamino)isophthalic acid.[5]Synthesis of alkyl-substituted pyrroles in the absence of catalyst and organic solvent.[6]Synthesis of dithioacetals from acetals by transthioacetalisation in a solvent free environment.[7]Synthesis of polyamides (PAs) by the polymerization of terephthalic acid and diisocyanates.[8]Catalyze the addition of thiols to conjugated alkenes.[9]Dehydrochlorination of poly(vinyl chloride).
