| titleOfInvention | Method for preparing azoxystrobin |
| abstract | In the present invention, azoxystrobin is obtained by reacting a 2-cyanophenol or 2-cyanophenol salt with a compound represented by the formula (I) under the catalytic conditions of the trimethylamine catalyst to obtain the azoxystrobin represented by the formula (II). By providing a manufacturing method of, the reaction yield of the product azoxystrobin can be increased to 98% or more, and the yield of the product obtained by separation reaches 95% or more, and post-treatment is simplified. The trimethylamine catalyst is recoverable and can be used repeatedly for the synthesis of the target product, azoxystrobin, thereby reducing costs and reducing total nitrogen and COD in wastewater, thus making it cost- and environmentally friendly and remarkable and suitable for industrial production. . |
