Pyraclostrobin intermediate nitrobenzene synthesizing system

Abstract

The invention discloses a pyraclostrobin intermediate nitrobenzene synthesizing system. The synthesizing system comprises a condensation system, a first centrifugation system used for crystallization and centrifugation, a refining system, a second centrifugation system used for crystallization and centrifugation, and a drying system which are arranged in sequence. An automatic control system is separately connected with the condensation system, the first centrifugation system used for crystallization and centrifugation, the refining system, the second centrifugation system used for crystallization and centrifugation, and a sensing system, the sensing system is separately connected with the automatic control system, the condensation system, the first centrifugation system used for crystallization and centrifugation, the refining system, the second centrifugation system used for crystallization and centrifugation, and the drying system. By means of the pyraclostrobin intermediate nitrobenzene synthesizing system, the production safety performance is improved, the operation is more flexible, manpower is saved, the production efficiency is improved, and meanwhile, the reaction raw materials and the materials of intermediate products are more precise, so that the quality of the product is improved. Meanwhile, the situation that the bodies of operating workers are harmed by toxic products is avoided, and the automation degree is high.

Description

technical field [0001] The invention relates to the field of pesticide production, in particular to a synthesis system for pyraclostrobin intermediate nitrobenzene. Background technique [0002] Pyraclostrobin is a new broad-spectrum fungicide. Mitochondrial respiration inhibitor. It has protection, treatment, and leaf osmotic conduction effects. Generally, the medicine is sprayed 3 times, and the medicine is sprayed once every 10 days. The frequency of spraying depends on the condition. It is safe for cucumbers and bananas, and no phytotoxicity has been seen. [0003] Nitrobenzene is an intermediate for the production of pyraclostrobin. In actual production, the equipment has a single function and cannot form a production line. This wastes production time in production, and the reaction volume will be inaccurate when using conveying tools. At the same time The raw materials and intermediates or some by-products of product production are easy to volatilize, resulting in ...

Problems solved by technology

[0003] Nitrobenzene is an intermediate for the production of pyraclostrobin. In actual production, the equipment has a single function and cannot form a production line. This wastes production time in production, and the reaction volume will be inaccurate when using conveying tools. At the same time The raw materials and intermediates or some by-products of product production are easy to volatilize, resulting in the generation of poisonous gas in the production workshop, and because the existing production automation is low, and production requires a lot of manpower, it will cause great harm to the human body. And the production rate is not high
