2,4-Dichlorophenoxyacetic acid (2,4-D) is widely used as a herbicide and my country is the world’s leading producer.
2,4-Dichlorophenoxyacetic acid, referred to as 2,4-D, is an organic compound with the chemical formula C8H6Cl2O3. It appears as a white to yellow crystalline powder, slightly soluble in water and oil, and soluble in ethanol. 2,4-Dichlorophenoxyacetic acid is a common chemical product, mainly used in the agricultural field as a herbicide, plant growth promoter, etc.
At present, the mainstream production technology route of 2,4-dichlorophenoxyacetic acid is chemical synthesis, including two major synthesis routes: first chlorination and post-chlorination. The first chlorination synthesis route refers to the process of using phenol as raw material, first undergoing a chlorination reaction to obtain 2,4-dichlorophenol, and then performing a condensation reaction with chloroacetic acid under alkaline conditions to generate 2,4-D; post-chlorination The chemical synthesis route refers to the process of using phenol as raw material, first performing a condensation reaction with chloroacetic acid, and then undergoing a chlorination reaction to generate 2,4-D.
2,4-Dichlorophenoxyacetic acid has dual-purpose characteristics. It can be used as a herbicide and a plant growth regulator. It can be absorbed into the plant through the roots, stems and leaves, interfering with the balance of active hormones in the plant and inhibiting it. Or promote the growth of plant organs, and is widely used to prevent and remove broadleaf weeds and germinating grass weeds in the growth of rice, corn, wheat and other crops. At the same time, 2,4-dichlorophenoxyacetic acid also has the advantage of good compatibility and can be mixed with herbicides such as atrazine and prometryn, or with acidic fertilizers such as ammonium sulfate to increase the weeding effect.
2,4-Dichlorophenoxyacetic acid was the first organic synthetic herbicide synthesized in the 1940s. After more than 80 years of development, it has become a low-cost and widely used phenoxyacetic acid organic herbicide on the market. . Many companies in my country have entered the 2,4-dichlorophenoxyacetic acid market, including Jiangxi Tianyu Chemical, Tangshan Shenghong Chemical, Gansu Xinhengmao Technology, Jilin Lvsheng Pesticide Chemical, Nantong Tahoe Chemical, Zhejiang Dayou Chemical, Shandong Weifang Runfeng Chemical, Ningxia Gray Fine Chemical, Shandong Runbo Biotechnology, etc.
According to my country’s 2,4-dichlorophenoxyacetic acid (2,4-D) market from 2023 to 2027 released by the Industrial Research Center Market Monitoring and Future Development Prospects Research Report” shows that there are currently a large number of enterprises in China with an annual output of 2,4-dichlorophenoxyacetic acid of more than 10,000 tons, such as Gansu Xinhengmao Technology, Nantong Tahoe Chemical, Jiangxi Tianyu Chemical, etc., with the gradual release of production capacity of local enterprises, my country has become a major producer of 2,4-D in the world. On the basis of meeting domestic demand, the production capacity can also be exported abroad in large quantities, and the market development space is wide. .
Industry analysts said that 2,4-dichlorophenoxyacetic acid is a type of dual-purpose pesticide The product can be used as both a herbicide and a plant growth regulator. After more than 80 years of development, it has now become a highly cost-effective and widely used herbicide in the domestic and foreign pesticide markets, with a broad market development space. At present, my country has a relatively high supply capacity of 2,4-dichlorophenoxyacetic acid and is one of the major producing countries in the world. The development trend of the industry is good.
