| Hazard Information | Back Directory | [Chemical Properties]
white powder | [Uses]
A compound that displays antibacterial properties | [Uses]
Displays antibacterial properties due to the presence of the quaternary amine and the counter ion. | [Preparation]
Tetrabutylammonium hydrogen sulfate can be prepared from tetrabutylammonium azide by treating it with potassium hydrogen sulfate and 10% aqueous sulfuric acid in aqueous medium or from tetrabutylammonium thiocyanate by treating it with relatively concentrated sulfuric acid (70%) at 75 °C.
 | [General Description]
Tetrabutylammonium bisulfate, a quaternary ammonium salt, is a phase-transfer reagent. | [Purification Methods]
The sulfate crystallises from acetone. It has been used as a phase transfer catalyst. | [References]
