Pyridine, also known as azabenzene, has a chemical formula of C5H5N and refers to a six-membered heterocyclic compound containing one nitrogen heteroatom. Pyridine appears as a colorless or slightly yellow liquid with a foul odor and is miscible in petroleum ether, water, ether, benzene and alcohol. Pyridine has the characteristics of irritation, flammability, and low toxicity, and is widely used in chemical industry, medicine, pesticides, rubber and other fields.

There are many methods for preparing pyridine, including coal coking by-product recovery method, separation method, chemical synthesis method, etc. The chemical synthesis method is the mainstream preparation method of pyridine. It uses α-methylpyridine as the main raw material and obtains the finished product through processes such as heating, cooling, distillation, and filtration. This method has the advantages of low operating cost, simple operation, and easy parameter control. Suitable for large-scale production. After years of development, the maturity of my country’s pyridine production technology has not improved, providing favorable conditions for industry development.

Pyridine compounds are the downstream products of pyridine and are the heterocyclic compounds with the widest range of applications, including bromopyridine, halogenated pyridine, hydroxypyridine, alkylpyridine, chloropyridine, etc. Pyridine compounds are rich in types and have strong demand in the field of pesticides. Fluroxyfop, fluroxypyr, acetamiprid, flufenopop, etc. are commonly used pyridine pesticides in my country. As the market share of pyridine compounds increases, the prosperity of my country’s pyridine industry continues to increase.

Pyridine is widely used in chemical industry, medicine, pesticides, rubber and other fields. In the chemical industry, pyridine can be used as an important fine chemical raw material for the production of pyridine compounds; in the pharmaceutical field, pyridine can be used to produce pharmaceutical intermediates, including isonicotinic acid, β-picolinic acid and nicotine; in the pesticide field, pyridine It can be used to produce the pesticides chlorpyrifos-methyl and chlorpyrifos; in the rubber field, pyridine can be used to produce polyurethane rubber and rubber vulcanization accelerators and other products. According to the “2023-2028 China Pyridine (Azabenzene) Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center ” shows that driven by downstream demand, my country’s pyridine production capacity continues to expand, with a year-on-year growth of nearly 10% in 2022, and has become one of the world’s major producing countries.

At present, Asia-Pacific countries and regions dominate the global pyridine market, accounting for nearly 60%. There are many pyridine manufacturers in my country, mainly including Xinxiang Hengji Chemical Co., Ltd., Tesco Chemical (Hubei) Co., Ltd., Nanjing Red Sun Co., Ltd., Lier Chemical Co., Ltd., Nantong Acetic Acid Chemical Co., Ltd., and Weifang Xiangvis Chemical Products Co., Ltd., etc.

Industry analysts said that as an organic compound, pyridine has broad application prospects in many fields. my country is a major producer and consumer of pyridine, and its production capacity continues to expand driven by market demand. Pyridine compounds are pyridine end products with strong demand in the field of pesticides. With the increase in the market share of end products, the development speed of the pyridine industry has further accelerated.
