Tetrabutylammonium bromide is a chemical compound from the group of quaternary ammonium compounds and bromides .
use
TBAB is used in phase transfer catalysis and as a synthesis base. In addition, TBAB can be used as an electrolyte and as a solvent. TBAB is often used analogously to an ionic liquid , although it is not counted as such due to its melting point of over 100 ° C. It can also be used as a microwave absorber in syntheses. Furthermore, TBAB can be used for the electrochemical bromination of aromatics .
