| titleOfInvention | Synthesizing process of Janus green B |
| abstract | The invention relates to a synthesis method of Janus green B, which comprises the following steps: adding methylene violet 3RAX to acid water, slowly dropwise adding sodium nitrite aqueous solution, reacting for 1-5h while controlling the temperature at minus 5 to 25 DEG C, and then adding N,N-dimethylaniline, wherein the molar ratio of methylene violet 3RAX to N,N-dimethylaniline is 1:1-2; and keeping reaction for 1-10h, after reaction is finished, carrying out reduced-pressure treatment to be dry, dispersing residue in saturated brine, filtering, and drying the filter cake to obtain the target compound Janus green B. The synthesis method has the benefits that a method, which takes p-phenylene diamine and N,N-diethylaniline as starting raw materials to prepare Janus green B by complete synthesis, is designed and implemented, the raw materials are easily available, the process is simple and the method has certain industrialization value. |
