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).
