Description
Technical Field
[0001] The utility model relates to the technical field of pesticide production, in particular to a feeding device for tebuconazole production. Background Art
[0002] Tebuconazole is a highly effective, broad-spectrum, systemic triazole fungicide with the advantages of protection, treatment, eradication and long lasting effect. It is mainly used as a seed treatment agent and foliar spray to prevent and control various fungal diseases of crops such as wheat, rice, peanuts, vegetables, bananas, and apples. It can effectively prevent and control diseases caused by Puccinia, Powdery Mildew, Pyrococcus, and Septoria, such as powdery mildew, root rot, smut and various rust diseases of cereals.
[0003] At present, the main method for producing tebuconazole is to use pentacyclic oxide and 1,2,4-triazole as raw materials, N-methylpyrrolidone as solvent, adopt a one-pot method, and supplement with catalysts such as KOH, NaOH, triethylamine, etc., keep warm at 105°C for 10 hours to form a solution containing tebuconazole, and finally separate and purify to obtain tebuconazole. The one-pot method can maximize the content and yield of tebuconazole and increase the yield of tebuconazole. At the same time, different types of catalysts need to be added at different reaction stages. However, when the catalyst is added to the existing tebuconazole production feeding device, it is necessary to open the injection port to feed the catalyst into the device. When the injection port is opened, it is easy to cause the temperature in the device to fluctuate and cannot maintain the stability of the reaction temperature in the device. The temperature fluctuation will affect the reaction, thereby affecting the final yield of tebuconazole. At the same time, the harmful gases and high-temperature airflow in the device will escape from the injection port to the outside of the device, which will cause harm to the personal safety of the staff. Therefore, it is urgent to develop a feeding device for tebuconazole production to improve the above technical problems. Utility Model Content
