-
Paragraph 0025-0028, (2020/06/02)
The invention discloses a method for continuously synthesizing a benzothiadiazole compound, comprising the following step: by using an o-mercaptoaniline compound, sodium nitrite and water as reactionsubstrates in a continuous flow reactor, a diazotization-coupling reaction is carried out at certain temperature under certain pressure to obtain the benzothiadiazole compound. By adopting the technology, no protonic acid participates, and water is used as a reactant and a solvent, so that the method is green and environment-friendly. The continuous flow reactor is used, online materials are small, the process is intrinsically safe, and the method is suitable for large-scale production.
