Second, the Synthetic Route we will recommend is the most important for your reference?

First, synthesis line ofTetrabutylammonium bromide CAS NO.1643-19-2  as follows

Synthetic method

The synthesis method of tetrabutylammonium bromide usually involves the reaction of tetrabutylammonium hydroxide and hydrogen bromide. The specific steps are to dissolve an appropriate amount of tetrabutylammonium hydroxide in a suitable solvent, then slowly add hydrogen bromide dropwise while heating the reaction mixture. After the reaction is completed, pure tetrabutylammonium bromide product is obtained through process steps such as distillation and crystallization. In industrial production outside the laboratory, other larger scale synthesis methods can also be used.
