Pesticide intermediates are products produced by processing agricultural raw materials. They are intermediate media that combine two or more substances. In pesticides, it can be understood as a synergist and an intermediate material for the production of pesticides.
Common types: plant growth regulators: prochloraz (DA-6), clopidourea (KT-30), sodium dinitrophenol, 6-BA, cytokinin α- Sodium naphthyl acetate, 5-nitroguaiacol sodium, indole butyric acid, etc.
China is a major producer and supplier of pesticide fine chemical intermediates in the world, and its 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, acaricide sulfone, sodium pentachlorophenol, pentachlorophenol, etc; O-cresol is mainly used in the synthesis of high-efficiency herbicides; Catechol is an important intermediate of carbofuran, propoxur, and ethicarb, which are new carbamate pesticides with low toxicity and high efficiency; Nonylphenol is a multi-purpose non-ionic surfactant, which is widely used as pesticide emulsifier; M-cresol is mainly used to synthesize pesticides and pesticides.
In recent years, as China has gradually strengthened 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 restriction of the use of lindane, the traditional raw materials of Trichlorobenzene are increasingly reduced in foreign developed countries and regions, and the production of organochlorine products is also gradually reduced, which also leads to the current global supply of Trichlorobenzene, especially high-purity 1,2,4-trichlorobenzene. All these factors provide a good opportunity for the production and development of 1,2,4-trichlorobenzene in China.
The new carbamate insecticides produced by catechol, such as carbofuran, propoxur, acetochlor, etc., are recommended by the World Health Organization as excellent varieties of household pest and storage pest control agents due to their low toxicity and good effect, and the market demand will gradually increase.
Nonylphenol is the largest product among alkyl phenols. It has good functions of decontamination, wetting, penetration, dispersion, solubilization and emulsification. It is widely used as pesticide emulsifier and the most important intermediate in petrochemical industry and organic synthesis industry. The market demand for m-cresol has basically maintained an average annual growth rate of 8% to 10%, and the development rate 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 general path to achieve the national goal of energy conservation and emission reduction and develop a low-carbon economy, the state attaches great importance to it. It is also very beneficial to the development of fine chemical pesticide intermediate industry.
Therefore, China's fine chemical pesticide intermediates industry has a very good development prospect under the dual beneficial impact of increased market demand and the development encouraged by the government.
