Method for preparing tetrachlorohydrazine by adopting microchannel reactor

The invention belongs to the technical field of chemical synthesis, and particularly relates to a method for preparing tetrachlorohydrazine by adopting a microchannel reactor. O-chlorobenzaldehyde and hydrazine hydrate are subjected to a condensation reaction to generate dichlorohydrazine, and then dichlorohydrazine and chlorine are subjected to a chlorination reaction in the microchannel reactor to generate tetrachlorohydrazine. According to the method, o-chlorobenzaldehyde and hydrazine hydrate are taken as raw materials, dichlorohydrazine is generated through condensation, chlorine is taken as a chlorine source after condensation products are dissolved with a dry organic solvent, tetrachlorohydrazine is generated through the microchannel reactor, and the method has the advantages of being high in production efficiency and purity, easy and convenient to operate, safe, capable of achieving continuous production and the like and is suitable for industrial production. 本发明属于化学合成技术领域，具体而言，涉及一种采用微通道反应器制备四氯联肼的方法。邻
