Descrizione generale

The product is ~40% 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.

Applicazioni

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

Avvertenza

may crystallize; can be redissolved on heating to 40°C
