In the fine chemical industry, the production of pesticides is regarded as a process highly dependent on safety, purity and stability. In the entire pesticide manufacturing chain, nitrogen, this invisible role, plays a crucial one. From synthesis reactions to product packaging, from tank protection to equipment purging, nitrogen almost runs through the entire production process.

A large number of organic synthesis reactions are involved in pesticide manufacturing, and these reactions often need to be carried out in an anaerobic environment. Many raw materials, intermediates and finished products of pesticides have characteristics such as being prone to oxidation, explosion and flammability. Once they come into contact with oxygen or water vapor in the air, it will not only cause the reaction to get out of control and the product to deteriorate, but may even lead to safety accidents. Therefore, using high-purity nitrogen as a protective gas has become a standard operation in the industry.

Typical application scenarios of nitrogen in pesticide manufacturing are as follows：

 1. Tank & Packaging Protection

Some pesticide products and raw materials are extremely sensitive to air. During the storage and packaging process, nitrogen filling and nitrogen sealing can effectively prevent oxidation, extend the shelf life and ensure the stability of the product.

2. Purging of the Conveying System

There are often residual solvents or reactive gases between pipes and valves. Using nitrogen for purging can thoroughly clean the interior of the equipment, prevent cross-contamination, and reduce safety hazards at the same time.

3. Auxiliary Gas During the Drying Process

Some pesticide components are sensitive to temperature and need to be dried in an inert atmosphere. At this time, nitrogen serves as the drying carrier, which can accelerate the drying speed and prevent oxidation and degradation.
