Pesticide intermediate

Pesticide intermediate

Pesticide is an important means of production in agricultural production, which plays an extremely important role in controlling diseases, pests and weeds, stabilizing and improving crop yield.

Although affected by the price of agricultural products, planting area, climate, inventory and other factors, pesticide sales will present certain cyclical fluctuations from year to year, but the demand is still relatively rigid.

According to data from the National Bureau of Statistics, the production of chemical pesticides nationwide has shown a decreasing trend since 2017.
In 2017, the output of chemical pesticides fell to 2.941 million tons, but in 2018 it fell to 2.083 million tons. In 2019, the output of chemical pesticides stopped falling and rose to 2.2539 million tons, up 1.4 percent year on year.

In recent years, China’s pesticide industry sales revenue as a whole maintained an increasing trend.
In 2018, thanks to the development of biological pesticides and the rise in product prices, as well as the expansion of demand for pesticides in cash crops such as cotton and infrastructure, the industry’s sales revenue was about 329 billion yuan.
It is estimated that the potential market size of China’s agriculture is still expected to rise in 2020.

Different pesticides require different intermediates in the production process.
A product produced by processing agricultural raw materials is also an intermediate medium that combines two or more substances together.
In pesticides can be understood as synergist, also known as organic intermediates.
Originally refers to the use of coal tar or petroleum products as raw materials for the synthesis of spices, dyes, resins, drugs, plasticizers, rubber accelerator and other chemical products, produced in the process of intermediate products.

The synthesis of intermediates is generally carried out in the reactor, and the generated intermediates are separated and purified, usually by extraction technology.
Pesticide intermediates and chloroform extraction is chemical enterprise common unit operation, the traditional operation process generally adopts the distillation column, this kind of operation process is complex, low extraction efficiency, power consumption is big, therefore with the deepening of social division of labor and the progress of production technology, most enterprises begin to technological upgrading, and choose a more effective process operation.
