Chemical compound
Tetrabutylammonium bromide (TBAB) is a quaternary ammonium salt with a bromide commonly used as a phase transfer catalyst.[2] It is used to prepare many other tetrabutylammonium salts by salt metathesis reactions. The anhydrous form is a white solid.[3]
In addition to being cheap, tetrabutylammonium bromide is also environmentally friendly, has a greater degree of selectivity, is operationally simple, non-corrosive, and can be recycled easily as well.[4]
