| titleOfInvention | A kind of synthetic method of novel insecticide fluorazine |
| abstract | The invention discloses a method for synthesizing a novel insecticide fluoxazuron, which is characterized by comprising the following synthesis steps: 1) using 2,6-dichloro-4-aminophenol as raw material, and potassium hydroxide as acid binding agent agent, DMF is a solvent, reacts with 2,3 dichloro-5-trifluoromethylpyridine, after the reaction is completed, DMF is evaporated under reduced pressure to 140 ° C to finish, filtered to remove inorganic salts, and then concentrated under reduced pressure to recover DMF, the residue Add toluene and tap water, stir, stand for layering, and the toluene solution of the upper layer is refluxed to separate water to obtain toluene of 3,5-dichloro-4-(3-chloro-5-trifluoromethyl-2-pyridyloxy) aniline solution; the invention has high yield and short reaction time, adopts toluene as a solvent, utilizes the azeotrope property of toluene and water to ensure anhydrous reaction conditions, and has high product yield and good quality. |
