General description

The product is 53.5-56.5% solution of tetrabutylammonium hydroxide in H2O. Tetrabutylammonium hydroxide has been synthesized from tetrabutylammonium iodide. TBAOH dissolved in anhydrous isopropyl alcohol is widely employed as titrant for weak acids.

Application

Tetrabutylammonium hydroxide solution (TBAOH) may be used in the following studies:
  • For the dissolution of 10 wt% cellulose under room temperature conditions.
  • As a catalyst during the synthesis of 1,2,4-oxadiazoles.
  • Preparation of TBAOH salts of fatty acids.
