Tetrabutylammonium bromide (TBAB) is a quaternary ammonium salt, specifically a white, crystalline solid, that is widely used as a phase transfer catalyst in organic chemistry. It's known for its ability to facilitate reactions between substances that are otherwise immiscible, like those in water and organic solvents, by transporting reactants across the phase boundary. TBAB is also studied for its use in electrochemistry and as an ionic liquid.

Industrial Uses

1. Performance Chemicals

  • Phase Transfer Catalyst (PTC): TBAB is a common PTC, enabling reactions between compounds that are not readily soluble in the same solvent. It enhances reaction rates by facilitating the transfer of reactants across phase boundaries
  • Organic Synthesis: TBAB is used in various organic reactions, including substitution and elimination reactions.  It helps dissolve ionic reactants in organic solvents, improving reaction efficiency and yields.
  • Activator: It also acts as an activator or additive in non-PTC conditions for substitution and cross-coupling reactions.

2. Pharmaceuticals

  • Pharmaceutical Intermediate: TBAB is also used as an intermediate in the production of certain pharmaceutical compounds. It acts as a building block in the synthesis of various APIs.

3. Polymers & Resins

  • Polyureas: TBAB, in its molten state, has been used as a green reaction medium for the synthesis of polyureas, offering higher yields and viscosities compared to traditional methods. 
  • Polymer Solar Cells: TBAB is utilized in the synthesis of polymer solar cells. 
  • Polyamides: TBAB is involved in the polymerization of terephthalic acid and diisocyanates to form polyamides.
