An expeditious and highly efficient continuous-flow process was developed for the synthesis of 3-(mesitylthio)-1H-1,2,4-triazole. The starting material 2,4,6-trimethylaniline was diazotized to give diazonium chloride, followed by azo-coupling with 1H-1,2,4-triazole-3-thiol and dediazoniation to provide 3-(mesitylthio)-1H-1,2,4-triazole in 85% yield with a productivity of 344 g/h. The side reactions such as hydrolysis, dimerization, and intramolecular coupling were significantly inhibited by the continuous-flow technology.

The invention discloses a method for preparing 3-(2, 4, 6-trimethylphenylthio)-1, 2, 4-triazole. The method comprises the following steps: mixing 2, 4, 6-trimethylaniline with an aqueous solution inorganic acid to prepare an ammonium salt solution; mixing 3-mercapto-1, 2, 4-triazole, inorganic base and an alkane alcohol to prepare a triazole solution; mixing the ammonium salt solution, a nitrite aqueous solution and an inert solvent and then enabling the mixture to enter a first tubular reactor for carrying out a diazotization reaction, and mixing materials, obtained after the diazotization reaction, with the triazole solution and reaction auxiliary agents, enabling the mixed liquid to enter a second tubular reactor for carrying out denitrification reaction, and enabling the materials, obtained after the denitrification reaction, to stand for layering; taking an aqueous layer and adding acid to adjust the potential of hydrogen (pH), and then carrying out centrifugal separation to obtain a solid crude product; drying to obtain white or pale yellow solid, i.e., the 3-(2, 4, 6-trimethylphenylthio)-1, 2, 4-triazole. The method adopts a tubular reaction continuous operation mode, thus being more convenient in realization of process automation and increasing the production efficiency. Due to the introduction of the inert solvent into the diazotization reaction and the denitrificationreaction, other colored impurities such as tar can be extracted in situ, and the purity of the product is improved.
