| titleOfInvention | Production process of difenoconazole |
| abstract | The invention discloses a production process of difenoconazole. The production process comprises steps as follows: etherification: parachlorophenol and solid potassium hydroxide which are well weighed and metered m-dichlorobenzene are put into an etherification reaction kettle, and etherate is obtained and transferred to a next procedure; acylation: etherate obtained in the etherification step, a small amount of aluminum trichloride and metered methylene dichloride are added to an acylation kettle to be stirred and mixed at the room temperature, acetyl chloride is dropwise added for a reaction, and acylate is obtained and transferred to a next procedure; cyclization: acylate obtained in the acylation step as well as propylene glycol and cyclohexane which are metered is put into a cyclization kettle at the room temperature, and materials are transferred to a next procedure after the materials are cooled to the room temperature by cooling water; bromination: a cyclization material is introduced into a bromination kettle at the room temperature, is bromized by dropwise adding bromine and is added with water for washing, waste water obtained through washing is sent for waste water treatment, and bromide is obtained and transferred to a next procedure; condensation: the bromide obtained in the bromination step, triazole, caustic soda flakes and dimethyl sulfoxide are put into a condensation reaction kettle. According to the production process of the difenoconazole, the reaction time of the process is shortened, the yield is increased, three wastes are fewer, and clean and environment-friendly production is realized. |
