| titleOfInvention | The technique that a kind of oxidizing process prepares ethiprole |
| abstract | The invention discloses a kind of oxidizing process prepares the technique of high-purity ethiprole, by 5 amino of appropriate raw material, 3 cyano group 1（2,6 dichloro-4,4 trifluoromethyls）4 ethylsulfinyl-1 base pyrazoles（I）In organic solvent, there is oxidation reaction in the case where fatty acid, hydrogen peroxide are participated in, after the completion of oxidation reaction, reducing agent is added while control system temperature, then system acid-base value is adjusted with NaOH solution, then crystallisation by cooling sucking filtration obtains crude product ethiprole, crude product ethiprole after temperature rising reflux（Ⅱ）It is purified that certified products are obtained；Wherein, organic solvent is from least one in chloroform, dichloromethane, dichloroethanes.Simple production process of the present invention, efficiency high, by-product are few, be obtained for larger breakthrough, and material toxicity is relatively low on product yield and product purity, and environmental pollution is less, and production controllability is good. |
