Rubber chemicals domestic production of raw materials Nitrochlorobenzene

Nitrochlorobenzene the past 10 years our country's rapid increase in production capacity, by the end of 2002 Nitrochlorobenzene domestic capacity by 1990 to 80,000 Ca increased to 380,000 t / a, the world's total production capacity of the device Nitrochlorobenzene in 650,000 t / a, China's total global production capacity of nearly 60 percent, to be a truly world Nitrochlorobenzene major producers and suppliers. Due to environmental pressures and the rapid development of Chinese products, foreign enterprises were forced to shut down its main requirements to buy from China, currently South Korea, Japan and India, each year China's imports from the considerable number of nitrochlorobenzene.
Nitrochlorobenzene not only our country's total production capacity increased rapidly, the highest in the world, but also in the size of the device, the synthesis technology and product quality has reached internationally advanced levels, currently the world's largest 100,000 t / a single Sets of equipment, computer companies to adopt automatic control system, the quality of products to meet the world's advanced level. In recent years, domestic Nitrochlorobenzene highly competitive, especially in the petrochemical plant in Nanjing, Yangzhou group of pesticides, Anhui Bayi Chemical Co., Ltd., three of the fastest growing, the three companies currently existing production capacity to reach 250,000 Ca, the total gross domestic 65% of capacity, more than the total domestic market demand, it can be said that the three companies will dominate the future of the domestic and even global nitrochlorobenzene production and trade. At present, the three have formed strong separation of the situation, many small and medium-sized enterprises Nitrochlorobenzene, no matter which side were unable to compete with the above-mentioned three companies to compete, be doomed. In order to have a head start in the next competition, the three have Nitrochlorobenzene extension of the existing devices, but also claims that after the expansion of its production capacity will reach 100,000 t / a.
Nitrochlorobenzene in the future development strategy should be the key to increasing the connotation of the device, relying on scientific and technological progress and constantly improve and upgrade the existing large-scale installations, and more importantly, rely on large-scale Nitrochlorobenzene devices, the development of downstream production well -, To form a Nitrochlorobenzene-based fine chemical products tree to the device's excellent quality, and reasonable package of high value-added downstream products to be effective, is the only way to the next competition to gain market advantage, the Leading.
Despite the current domestic nitrochlorobenzene production technology and product quality has reached world-class level, but there is still a certain space development. With a high level of foreign production facilities compared with our existing Nitrochlorobenzene devices are still not sufficiently sophisticated quality of goods and stability, nitration technology advanced enough, the level of automation, control of environmental pollution and lack of comprehensive utilization of by-products and many other aspects of existence Gap. At present, the main Nitrochlorobenzene large-scale installations are already using DCS automatic control, but in the automatic matching system update, the operative level of proficiency, there is still a big gap, but also in other domestic mold and a number of key Tower's selection of an issue, and so on.
In the previous domestic Nitrochlorobenzene device the size of a small domestic market demand, continue to rely solely on the sale of Nitrochlorobenzene can survive, but the face of such huge scale of a world-class device, simply hopes on the production and sale of a small number of products involved in downstream Competition, let alone win the competition. Even survival impossible. And the development of downstream products not previously recognized, in order to Nitrochlorobenzene a raw material for further processing to produce a number of organic intermediates, such as nitro-phenol, o-phenol, o-aniline, p-nitroaniline, Aminodiphenylamine, and so on, but to Nitrochlorobenzene based on the formation of fine chemical products chain, in the face of large-scale Nitrochlorobenzene device, simply by building a Nitrochlorobenzene down to the fine chemicals derived from the Chain products are not too many competitive, but should form a lush branches of the tree products, so that the upper reaches of product quality and content of large-scale, mid-stream high-quality products and clean production technology, the lower reaches of fine products, serialization, and equipment GM And of high value-added. This scale of the whole device can Nitrochlorobenzene vitality. Therefore, a reasonable choice of the product chain and the building of the new century has become the new situation Nitrochlorobenzene development.
