Pyridine and its derivatives as a high value-added fine chemical products, are widely used in pesticides, pharmaceuticals, dyes, spices, rubber, feed and daily-use chemicals and other fields, as an important pesticide raw material, pyridine prices in recent years can be said to be Pesticide market vane. With the development of economy, the demand for pyridine compounds in China has also increased year by year. Although the current domestic production capacity has exceeded 50,000 t/a, the products of American Rayleigh Co. (Nantong) are mainly used for export, and the Red Sun Group Pyridine products are also used for internal production and digestion. There is still a gap in the demand for domestic pyridine products. Therefore, many companies currently want to invest in pyridine projects, but they are rejected by the high threshold of pyridine production technology. The pyridine production process, the development of new products of substituted pyridines such as alkylpyridines, chloropyridines, and cyanopyridines, and the application of pyridine compounds in new fields such as pesticides and pharmaceuticals, can be said that the development of the entire pyridine industrial chain has become a matter of great concern to everyone. Focus issue. Demand for pyridine and its series of products has been very strong in China's market. In recent years, with the development of the industrial sector, the demand for pyridine and its products has increased. However, domestic production cannot meet the growth in demand and it is expected that market demand will continue to be very strong in the future.
The production of pyridine is mainly composed of synthetic methods and separation methods, in which the production of synthetic methods accounts for more than 95% of the total output. For a long time, our country's pyridine production has been using the traditional coal tar separation method, and its production capacity is small. The annual production capacity is only 100-200 tons, and the product has many impurities, which can not meet the production needs. It is imported from foreign countries every year. The amount is more than 10,000 tons.
Since the beginning of the 21st century, China has begun to use synthetic methods for the production of pyridine. In 2001, the 16,000-ton synthetic pyridine and its series of products from Sino-U.S. joint-venture Nantong Rayleigh Co., Ltd. were successfully put into production, filling the gap in the domestic synthesis of pyridine production. At present, the The production capacity of the company's pyridine series products has been expanded to 25,000 tons, but its products are mainly used for export and directional supply of supporting companies, and are rarely supplied to other domestic manufacturers. In 2007, Nanjing Hongsun Group's proprietary pyridine and its series of products were successfully put into production. At present, the company has an annual output of 11,000 tons of pyridine and its products in Nanjing Chemical Industry Park and Anhui Dangtu Chemical Park. The production of the device includes five products such as pyridine and 3-methylpyridine, but most of the pyridine series produced by the company is used for the production of pesticides and intermediates supporting devices of the company, and is rarely supplied to the market. Therefore, many domestic users have to rely on imports to maintain production.
At present, the major users of the pyridine series are pesticides and pharmaceuticals. In recent years, pesticides containing pyridyl groups have developed rapidly. Not only are there efficient insecticides and herbicides, but also highly effective fungicides have been developed, and a series of unique pesticides have gradually emerged. It is estimated that the global consumption of pyridine pesticides will increase by more than 15% in the next few years, which will greatly exceed the average level of the pesticide industry, and the demand for pyridine series products will increase by more than 20%. China is the world’s largest producer and exporter of pesticides. At present, there are more than 400 pesticide production enterprises in the country. Many companies now regard pesticides containing pyridine groups as the direction of innovation and development. It is expected that with the rapid development of domestic pyridine pesticides, the Market demand for pyridine products will continue to grow.
In the pharmaceutical field, nicotinic acid/nicotinamide has the greatest demand for the pyridine series of products. About 35% of the world's pyridine series products are used to meet the demand for niacin/nicotinamide production. China is the world’s largest producer of niacin/nicotinamide. In the exporting countries, the annual output of nicotinic acid/nicotinamide has reached around 10,000 tons, with an annual export volume of more than 5,000 tons. The annual demand for 3-methylpyridine is only 3,000 to 4,000 tons. Nicotinic acid/nicotinamide is an important B vitamin product and is used in large amounts in pharmaceuticals and feed additives, particularly feed additives. About 75% of the world's nicotinic acid/nicotinamide is used in feed additives. In recent years, the production and export of nicotinic acid/nicotinamide in China have increased significantly year by year, and the demand for pyridine series products will increase in the future.
Over the years, the output of domestic pyridine series products can not meet the market demand, and it must be imported from foreign countries every year. In recent years, the amount of imports has increased continuously. In 2009, the import volume of pyridine series products in China reached 19,371 tons and the import amount was 73.52 million US dollars. Now the production of pyridine series products in the world is basically controlled by several large companies such as Rayleigh, Switzerland and Longsha. Due to their monopolistic nature, the prices of pyridine series products have been high and fluctuating for many years. It is expected that in the next few years, the output of pyridine series products in the Chinese market will be difficult to increase substantially, and demand will continue to rise. Therefore, a large number of imports will be made and prices will remain firm.
