At present, China has become a major producer and supplier of organic intermediates throughout the world. The scale of equipment has been continuously expanded, synthetic technology has been continuously improved, and international competitiveness has been strengthened. Product varieties basically meet domestic demand for fine chemicals. Looking ahead to 2007, China's organic intermediates industry will continue to maintain a rapid growth momentum, but at the same time there are also hidden concerns such as overcapacity, environmental pollution, and serious security issues. The entire industry is facing greater structural adjustments and many small and medium-sized backward devices. Will be eliminated. In 2007, the organic intermediate industry will exhibit the following features.
After nearly 10 years of rapid development of production facilities, China’s organic intermediate industry has taken a close look at large-scale production. At present, there are many domestic organic intermediate-scale devices that rank first in the world, such as nitrochlorobenzene and dichlorine. Benzene, chlorofluoroaniline, 2-naphthol, amino acid, turpentine, p-toluene sulfonic acid, etc.; Many organic intermediate devices are ranked first in Asia, such as morpholine, diphenylamine, sorbic acid, and p-methyl Phenol, o-chloroaniline, nitrotoluene, trimethylolpropane, m-phenylenediamine, 2,4-dichlorofluorobenzene, para-ester, H-acid, tert-butylamine, p-aminodiphenylamine, o-phenylenediamine, melamine , isopropylamine, chloroacetic acid, benzyl chloride, cyclohexylamine, chlorophenol and the like. In 2007, several sets of organic intermediate production facilities in the world or Asia will be built, such as 150,000 tons/year nitrochlorobenzene, 10,000 tons/year DSD acid, and 30,000 tons/year resorcinol. , 40,000 tons / year methyl isobutyl ketone, 25,000 tons / year chloroacetic acid, 12,000 tons / year dihydroxybenzene and other dozens of sets of large-scale organic intermediate devices. These devices will be put into operation and will further increase the international competitiveness of organic intermediates in China. The total production capacity of intermediates of many dyes, traditional medicines and pesticides and rubber and plastics additives in China accounts for more than 50% of the world's total production capacity. These products are mainly naphthalene-based organic intermediates, chlorinated aromatic intermediates, aromatic amines, and aromatics. Carboxylic acid products.
Advances in synthetic technologies have accelerated the increase in production capacity of organic intermediates in China, while also accelerating the pace of progress in synthetic technologies. In 2007, the development trend will continue in the past, mainly reflected in the following aspects: First, the development and application of cleaning unit operations is accelerated, such as Catalytic hydrogenation reduction, sulfur trioxide sulphidation, direct oxidation of air or oxygen, direct catalytic amination, adiabatic nitration, reactive distillation and other technologies; second, change raw material route according to market supply and demand and raw material price changes, expect to reduce production costs Reducing pollution, such as nitrobenzene synthesis of p-aminodiphenylamine, m-phenylenediamine catalytic hydrolysis of resorcinol, o-chlorotoluene to prepare o-toluidine, etc.; Third, the isomer adjustment technology will be highly valued The fourth is to optimize the design and selection of key equipment, more companies will choose to introduce advanced foreign equipment or manufacturing technology; Fifth, the promotion and application of solvent method; Sixth, the rapid development of large-scale petrochemical by-product separation and processing technology.
Strong demand in the downstream market Along with the rapid development of the domestic organic intermediates industry, China has now become a global production base for fine chemicals in dyes, traditional medicine, pesticides, rubber and plastics additives, and food and feed additives. In 2006, the output in these areas maintained a relatively high growth rate. For example, the output of dyes in 2006 was 1,285,300 tons, an increase of 21.11% over the previous year; the production of chemical raw materials was 1,705,300 tons, an increase of 37.70%; the output of chemical pesticides was 129.55 (100%). , an increase of 24.46%; rubber auxiliaries production is about 290,000 tons, an increase of 25.5%. In 2007 these areas will continue to maintain rapid growth in 2006. In addition, China's organic intermediates are still exported in large quantities. Exports of most varieties have continued to increase in recent years. At the same time, the structure of organic intermediates for export is also changing. Not only are there conventional generic intermediates, but some of the special fine chemical intermediates are also exported. With the steady and rapid economic development of our country, many domestic markets for medium and high-grade fine chemicals are gradually starting to start, and there is great potential in the domestic market. The strong demand in the downstream market has stimulated and stimulated the rapid development of the organic intermediate industry in China, ensuring that the organic intermediate industry in China continued to grow rapidly in 2007.
Accelerate Adjustment of Industrial Structure Due to the demand and prospect of domestic organic intermediates, many domestic organic intermediate products have been used in low-level and small-scale repetitive construction in the past decade. At present, the development of domestic organic intermediates is very uneven. Many world-scale and small workshops coexist. Many varieties have serious excess production capacity. With the increasingly fierce competition in the market, the domestic organic intermediate industrial structure will be strengthened in 2007. Through fierce market competition, some small and medium-sized production plants with serious environmental problems will face elimination.
Environmental protection and safety are highly valued. In 2006, there were serious problems in the production safety and environmental protection of organic intermediates in China. There have been a number of vicious accidents. It is no exaggeration to say that environmental pollution and safety production have become the major constraints on the development of organic intermediates in China. bottleneck. Therefore, in 2007, the state will pay more attention to the safety and environmental protection of organic intermediates, shut down some small and medium-sized enterprises with serious pollution, backward processing equipment, and poor safety, and will take effective measures to curb the transfer of organic intermediate pollution to the west and the mainland. . In this case, domestic organic intermediate production enterprises will further increase production end treatment, and new wastewater treatment technologies such as complexation extraction, liquid membrane separation, catalytic oxidation, new biological treatment, and resin adsorption will be further promoted. application. In 2007, more organic intermediate cleaning processes will be used in production. Safety management will also be strengthened and implemented.
