Yongnong plans to invest ¥150 million in technical transformation of the production line with 2,500 t/a Chlorfenapyr

On April 7, Yongnong's efficient plant protection product technology enhancement project was publicized before filing. 

Among the existing approved products of Yongnong, Chlorfenapyr has been approved in the "New 8,000 t/a of efficient pesticide technical project (project code 2020-330604-26-03-155072)", but the current situation has not been built. In the subsequent process design process of the unit, due to safety, yield, purity and other reasons, the process technology and equipment of the original approved cyclization, Tralopyril synthesis, bromination reaction, Chloromethoxyethane synthesis, Chlorfenapyr synthesis process were optimized and improved. The total investment of the project is 150 million yuan, and the planned completion time is December 2025.

The project code has been obtained (project code 2401-330604-99-02-571463). The main construction contents of the project are as follows: The project will use the existing plant area of No. 3 Weiqi East Road for construction, project transformation, use the existing standard workshop 8, as well as the existing warehouse, tank farm and environmental protection public facilities, purchase reactor, automatic closed centrifuge, dryer and other equipment, optimize the product process, and form an annual output of 2,500 tons of Chlorfenapyr technical (unchanged) production capacity. Annual by-product 5761.8 tons of hydrochloric acid; This project mainly carried out technical transformation and optimization of some process steps of Chlorfenapyr products. After the implementation of the project, the production capacity of the original drug will remain at the original approved production capacity, and no new pesticide production capacity will be added.
