Pesticide intermediates have great potential
With the approaching of the spring plowing season, demand for pesticides and fertilizers began to increase, prices have risen to varying degrees, increased the operating rate of fertilizer and pesticide companies, and brought opportunities for the development of China's fine chemical and pesticide intermediates industry. .
Zhong Jianzhi, a researcher in the chemical industry of China Investment Advisors, pointed out that China is the world’s major producer and supplier of intermediates for the production of pesticides and fine chemicals, and its development prospects are 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 such as dicamba, mitoxantrone, sodium pentachlorophenol, pentachlorophenol, etc.; o-cresol is mainly used for the synthesis of highly efficient herbicides; catechol is important The low toxic and highly effective novel carbamate pesticides carbofuran, protoporphyrin, ethamevidene intermediates; nonylphenol is a multi-purpose non-ionic surfactant, widely used in pesticide emulsifiers; m-cresol mainly used Synthetic pesticide pesticides.
In recent years, due to the gradual strengthening of the development and application of its downstream products at home and abroad, the demand for high-purity 1,2,4-trichlorobenzene has been strong in the international market. In addition, due to the banned and restricted use of lindane, in the developed countries and regions abroad, the traditional trichlorobenzene raw materials are increasingly reduced, and the production of organochlorine products is also gradually reduced, which also leads to the current global trichlorobenzene, especially high-purity 1 , 2,4-Trichlorobenzene is in tight supply. These factors have provided a good opportunity for the development of the production of 1,2,4-trichlorobenzene in China.
New carbamate insecticides produced from catechol, such as carbofuran, propoxcarb, ethamacetic, etc., have low toxicity and good efficacy, and are recommended by the World Health Organization for household pests and storage pest control agents. The fine varieties, the market demand will also gradually increase.
Nonylphenol is the largest product in alkyl phenols. It has good functions of decontamination, wetting and penetration, dispersion, and solubilization. It is widely used in pesticide emulsifiers and is the most widely used in petrochemical and organic synthesis industries. Important intermediates. As for the market demand for m-cresol, the growth rate is basically maintained at an average annual rate 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 environmentally friendly process, and it is a national energy-saving emission reduction target and a low-carbon economy. The general approach, the state's emphasis on its greatly increased. The development of fine chemical pesticide intermediates is also very beneficial.
Therefore, China's fine chemicals and pesticide intermediates industry has very good prospects for development under the dual favorable influence of increasing market demand and government encouragement.
The "2010-2015 China Pesticide Market Investment Analysis and Prospect Forecast Report" released by China Investment Advisor shows that the market demand for 1,2,4-trichlorobenzene in the world is more than 35,000 t/a, and will be in the next few years. It is increasing at an average annual rate of 10%. The pesticide produced by catechol is currently the mainstream insecticide species in China. In 2008, the pesticide industry consumed about 8,000 tons of catechol, and it is expected that in 2010, the domestic market demand for catechol will reach around 12,000 tons per year. In the next few years, the annual growth rate of nonylphenol in the Chinese domestic market will be 8%, and it is expected that by 2010, the domestic market demand will be around 70,000 t/a. The demand for m-cresol in the pesticide field has steadily increased and it is expected that by 2010, the domestic market demand will reach around 18,200 t/a.
