Nitrobenzene is mainly used to synthesize aniline, an important organic chemical raw material. At present, except for 1 or 2 companies that separately build nitrobenzene plants, all of them are matched with aniline plants, and most of the capabilities are basically matched, except for a small amount of solvents and reagents. In the field of fine chemical applications, the amount of nitrobenzene products is very small. In recent years, with the expansion of domestic aniline production capacity, the production capacity of nitrobenzene has shown a rapid growth trend. Industry insiders expect that the aniline production capacity in China will have a more serious surplus in the next few years. Therefore, it is of great significance for nitrobenzene to seek non-aniline use.
Rapid expansion of domestic production capacity Due to the favourable domestic market for aniline in recent years, there has been an upsurge in the construction of nitrobenzene and aniline in China. Major projects include: Jilin Petrochemical expanded its existing nitrobenzene and aniline plants to 280,000 tons and 200,000 tons respectively. It is expected to put into production in 2005; Lanzhou Petrochemical expands 100,000 tons of nitrobenzene and 70,000 tons of aniline has been completed and put into production; Shanxi Tianjiu Group has introduced construction of 180,000 tons of nitrobenzene and 130,000 tons of aniline from US DuPont Technology and construction has started. It is estimated that it will be completed and put into operation from the end of 2005 to the beginning of 2006; Jiangsu Melan is expanding 110,000 tons of nitrobenzene and 80,000 tons of aniline plant; Taixing Xinpu will expand the production capacity of nitrobenzene and aniline by 130,000 tons and 90,000 in 2005 respectively. T; Jiangsu Shuangliang Group plans to build 70,000 tons of nitrobenzene and 50,000 tons of aniline plant in 2005; the expansion of 140,000 tons of nitrobenzene and 100,000 tons of aniline project by Nanhua Company is under intense construction and is expected to run in September this year. Put into production. In addition, with the addition of nitrobenzene and aniline plants built for MDI, it is expected that the total production capacity of nitrobenzene and aniline in China will reach 1.5 million tons and 1.1 million tons respectively by 2007, and the production capacity of nitrobenzene will The 600,000 tons in 2004 will increase by 2.5 times, and oversupply may occur.
Market fatigue has appeared As aniline and nitrobenzene are supporting production, the price trend of aniline is to some extent represent the price trend of nitrobenzene. With the gradual increase of the price of raw material benzene in 2004, coupled with the domestic demand for aniline is in short supply, nitrobenzene has been operating at high prices. At the beginning of 2005, domestic prices of aniline remained strong. As many sets of domestic nitrobenzene and aniline plants were completed and put into operation one after another, downstream products such as traditional medicine, pesticides and dyes were affected by many factors. In the first half of 2005, exports decreased by a certain extent. , entered the international market blocked, the domestic market increased little, so in July 2005 the domestic aniline market has begun to show signs of weakness, the current price of aniline has dropped from the beginning of 15,000 yuan to 12,500 yuan. With the introduction of multiple sets of aniline units in the country in the second half of 2005, the excess situation of domestic aniline will become more pronounced, and the price of aniline will further decline. The price of raw materials benzene will be affected by crude oil, and there will not be much room for decline, so aniline and nitrate The profit margin of the benzene device will be further compressed.
Wide prospects for the development of new applications With the aniline market becoming weak, it is very important to develop the use and consumption of nitrobenzene and non-aniline. It is very important for the stable operation of nitrobenzene devices. In the future, domestic nitrobenzene will accelerate the development of downstream non-aniline products while increasing its export intensity.
With the rapid growth of China's nitrobenzene production capacity, China’s exports of nitrobenzene showed a rapid increase in 2005. From January to June, China’s exports of nitrobenzene were 4,672 tons, a year-on-year increase of approximately 95 times. It is expected that China’s nitro The export of benzene will exceed 10,000 tons. Due to the tight supply of aniline and nitrobenzene in neighboring countries, and the continuous use of foreign nitrobenzene downstream, nitrobenzene export prospects are very promising. In the future, China's nitrobenzene and aniline should increase export efforts. Participate in international competition.
Traditional applications of nitrobenzene include synthesis of dinitrobenzene, metanitrochlorobenzene, nitrobenzene sulfonic acid, azobenzene, etc. These products currently consume relatively stable nitrobenzene. About 20,000 tons of benzylbenzene, the future growth will not be too large, is expected to reach 25,000 tons in 2006. It is worth noting that in recent years, two very important intermediates have been developed using nitrobenzene as raw materials in China: First, p-aminodiphenylamine, an intermediate of the world's leading anti-aging agents, p-phenylenediamines, 4010NA and 4020. It is expected that the production capacity of aniline diphenylamine in China will reach 80,000 to 100,000 tons in 2006. If all of them are produced by nitrobenzene, about 50,000 to 60,000 tons of nitrobenzene will be consumed. The second is expected to be aminophenols. In 2006, the production capacity of p-aminophenol in China will reach 60,000 tons. At present, the domestic use of p-Nitrophenol iron powder reduction or hydrogenation reduction, but developed countries and regions mainly adopt clean and environmentally friendly nitrobenzene catalytic hydrogenation preparation, if domestic Switching to nitrobenzene production requires about 60,000 tons of nitrobenzene. Domestic as long as we continue to pay attention to the future trend of domestic nitrobenzene overstatement, increase the export of nitrobenzene and the downstream development of important downstream non-aniline intermediates, domestic nitrobenzene overcapacity situation will be eased.
