There are environmental problems in the production of difluorosulfen and green process research and development should be increased.

The chemical name of difluorosulfentrazone is 2′,6′-difluoro-5-ethoxy-8-fluoro[1,2,4]triazole[1,5-C]pyrimidine-2-sulfonanilide, It was developed by Dow Agricultural Science Company of the United States in the mid-1990s. It is the fifth triazolepyrimidine sulfonamide after sulfentrazone, saflufenacil, closufentriol and diclosufen. Herbicide-like varieties.

                                                                                                                                      Difsufensutrazone is mainly used to control broadleaf weeds in winter wheat, and its downstream is mainly in the wheat field herbicide industry. Wheat is one of the main food crops in my country. At the same time, my country is also the largest wheat producer and consumer in the world. Wheat field herbicides are indispensable in the wheat planting industry. In recent years, the demand for herbicides with low toxicity, high efficiency, environmental friendliness, and good persistence in wheat field herbicides has continued to increase, which in turn has promoted the increase in the market demand for difluorosulfen.

The United States is the country with the earliest development of the flusufen industry. In 1998, Dow AgroSciences (now Corteva Agricultural Sciences) of the United States took the lead in developing flusufen and successively developed it in Belgium, the United Kingdom, France, and the Netherlands. , Spain, the United States and other countries have been launched one after another. After that, more and more people became aware of the advantages of flusulam, a herbicide with low toxicity, high efficiency, environmental friendliness, and good long-lasting effect. The demand in the downstream market continued to increase, and many chemical companies saw its good applications. Prospects have also entered the market one after another and built a production line for fomesafen technical material. The market competition in the fomesafen industry has become increasingly fierce.

However, in recent years, global environmental awareness has gradually increased, and strict controls have been imposed on pesticides, a highly polluting industry, which has had a greater impact on the development of the flusulam industry. In addition, the rising prices of raw materials have also greatly reduced the price of flusulam. As for the profit margins of fenfossil companies, some flusufen manufacturers have withdrawn from the market, and the concentration of flusufen’s market has gradually increased. At present, the world’s largest flusulam manufacturers mainly include Corteva of the United States and Syngenta of Switzerland. In addition, Jiangsu Ruibang Agrichemical Co., Ltd., Shandong Zhongnong United Biotechnology Co., Ltd., Jiangsu Province Agricultural Hormone Engineering Technology Research Center Co., Ltd. and others have also occupied a position in the international market with their increasing international competitiveness. According to the“2022-2027 China’s flusulam + saflufenacil industry market in-depth research and development prospect forecast report” released by the Industrial Research Center span>Shows that in 2022, China’s flusulam production will be 450.2 tons.

Industrial analysts believe that flusulam is an important wheat field herbicide product. In the context of ensuring food security, its The importance is self-evident. However, it belongs to the chemical pesticide manufacturing industry and will produce waste gas, waste water, solid waste and noise during the production process. At present, most of the companies engaged in the production of raw materials in my country follow the unified national plan and enter chemical industry parks or industrial parks for production and operation. With the full implementation of the national sustainable development strategy, environmental pollution control standards are gradually improving. If relevant companies fail to continuously invest in environmental protection improvements and continue to comply with the requirements of various environmental protection regulations, they will face suspension, production restriction or administrative penalties. risk. Therefore, in the future, flusufen companies should continue to improve their production processes, adopt circular economy and clean production methods, continuously increase investment in environmental protection, and formulate and implement various preventive and safeguard measures to ensure their safe and stable production.
