Development status and trend analysis of pesticide intermediates industry in the 2018
Nov 30, 2018

From the point of view of industrial chain segmentation, pesticide products can be roughly divided into pesticide intermediates, pesticide raw drugs and pesticide preparations. Pesticide intermediates are used in the production of pesticide raw drugs, and pesticide raw drugs can not be directly applied to crops, must be based on the characteristics of its active ingredients and different control objects to make a suitable preparation form for application.

At the same time, people can also be used to compound different types of pesticides, to obtain a wider range of prevention and treatment of pesticide products. China's pesticide industry has established from the original drug production, intermediates supporting to the preparation processing, including a more complete industrial industry. With the development of new pesticides in the country, the development of some special intermediates has developed rapidly, such as fluorinated, cyanide-containing, heterocyclic intermediates, of which more prominent are chrysanthemum pesticide intermediates, such as chrysanthemum acid, two chloroacetic acid, butyric acid, ether aldehyde, propylene alcohol ketone. These intermediates can now be produced in China, the production sites are currently mainly concentrated in Shanghai, Zhejiang, Jiangsu regions. In addition, some pesticide intermediates process technical reform is also more active, the main results obtained are: isoprene synthesis of frequency ketone, methanol carbonyl synthesis of formic acid, acetic anhydride catalytic synthesis of chloroacetic acid, diethyl parathion methyl chloride new process, directional crystallization extraction of fine naphthalene, directional chlorination production of two chlorobenzene, phase transfer catalytic reaction, The synthesis of chlorine acetyl chloride by double ethylene ketone and the production of aromatic amine compounds by catalytic hydrogenation were produced.
