My country is the main producer and supplier of pesticide fine chemical intermediates in the world, and the development prospect is very broad. Among them, 1,2,4-trichlorobenzene, o-cresol, catechol, and nonylphenol are the most important pesticide intermediates. 1,2,4-Trichlorobenzene is mainly used in the synthesis of pesticides dicamba, acaricidal sulfone, sodium pentachlorophenate, pentachlorophenol, etc.; o-cresol is mainly used in the synthesis of high-efficiency herbicides; catechol is an important The intermediates of low toxicity and high efficiency new carbamate pesticides carbamate, propoxur and ethoxycarb; nonylphenol is a multi-purpose nonionic surfactant, widely used in pesticide emulsifiers; m-cresol is mainly used in for the synthesis of pesticides and insecticides.

In recent years, due to the gradual strengthening of the development and application of its downstream products at home and abroad, there is a strong demand for high-purity 1,2,4-trichlorobenzene in the international market. In addition, due to the prohibition and restricted use of lindane, traditional trichlorobenzene raw materials and the production of organochlorine products are gradually decreasing in developed countries and regions abroad, which has also led to the current global trichlorobenzene, especially high-purity 1 , 2,4-trichlorobenzene supply is tight. These factors have provided a good opportunity for the production and development of 1,2,4-trichlorobenzene in my country.

The new carbamate insecticides produced by catechol, such as carbofuran, propoxur, acetaminophen, etc., are recommended by the World Health Organization as one of the household pests and storage pest control agents due to their low toxicity and good effect. The high-quality varieties, the market demand will also gradually increase.

Nonylphenol is a bulk product among alkylphenols. It has good functions such as decontamination, wetting and penetration, dispersion, solubilization and emulsification. It is widely used in pesticide emulsifiers and is the most important in petrochemical industry and organic synthesis industry. the intermediate. As for the market demand for m-cresol, the growth rate is basically maintained at an average annual level of 8% to 10%, and the development speed is stable.

In addition, because fine chemical industry has the advantages of functionalization, high performance, special flowers, and high added value, it is a low-carbon and environment-friendly process, and it is a way to achieve the energy saving and emission reduction goals proposed by the state and develop a low-carbon economy. There is always a path, and the country's attention to it has greatly increased. It is also very beneficial to the development of the fine chemical pesticide intermediate industry.

Therefore, my country's fine chemical pesticide intermediate industry has a very good development prospect under the double favorable influence of the increase in market demand and the government's encouragement of development.
