| titleOfInvention | Preparation method of difenoconazole nitrate |
| abstract | A preparation method of difenoconazole nitrate comprises the following steps: carrying out microwave reaction on 2- (bromomethyl) -2- (2-chloro-4- (4-chlorophenoxy) phenyl) -4-methyl-1, 3-dioxolane and 1H-1,2, 4-triazole in the presence of an acid-binding agent, a catalyst and a solvent; dissolving a difenoconazole crude product obtained after distillation; dissolving a difenoconazole crude product, and adding nitric acid to form salt; filtering and drying to obtain a finished product of difenoconazole nitrate. The reaction condition for preparing the difenoconazole nitrate is milder, the reaction time is short, the solvent dosage is less, the steps are simple, the environment is protected, the method is suitable for industrial production, and the yield and the content of the final product are higher. |
