General description

Tetrabutylammonium hydroxide (TBAH) solution it is a strong organic base. It enables the dispersion of fatty acids in water at room temperature which allows the formation of emulsions and foams. TBAH is used as a titrant in the potentiometric titration of weak acids in non-aqueous media.

Application

Phase-transfer catalyst.
Tetrabutylammonium hydroxide solution may be used in the following processes:
  • Synthesis of carbon doped TiO2 (titanium dioxide).
  • Synthesis of C60 derivative-hydroxylated fullerene epoxide.
  • As a hydrolysis controlling agent in the prearation of TiO2 sol.
