Aqueous solution. | [Uses]
TBAOH may be used as an ion-pairing reagent in mobile phase preparation for reverse phase ion-pair high performance liquid chromatography during chromium (III) and chromium (VI) determination. | [Uses]
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. | [Preparation]
Tetrabutylammonium hydroxide was prepared by the ion exchange between gel type strong basic anion exchange resin(OH-) and aqueous solution of tetrabutylammonium bromide. | [General Description]
The product is 54.0-56.0% 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. | [Flammability and Explosibility]
Flammable |
