Steady Growth in Consumption The consumption structure has been quietly changing In recent years, with the rapid development of industries such as nylon and polyurethane in China, the consumption of adipic acid has steadily increased, and consumption has increased by an average of 20% from 2003 to 2008.
With the rapid development of polyurethane (PU) industrial sole materials and PU pulp market, the consumption structure of adipic acid in China has undergone great changes, from the production of nylon 66 salt to polyester used in the production of polyurethane materials. Mainly polyols, in addition there is a part for the production of adipic ester products, such as dioctyl adipate, unsaturated polyester resins.
In 2008, the demand for adipic acid in the polyurethane industry in China accounted for about 58.0% of the total consumption, nylon 66 salt accounted for 20.7%, and other areas accounted for 21.3%. The development of nylon plastics industry in our country is relatively slow, and the polyurethane industry is developing rapidly. Therefore, the consumption structure of adipic acid in China has a large gap with foreign countries. At present, the consumption of nylon salt in the United States, Western Europe, and Japan accounts for 90.7%, 33.4%, and 50.5% of adipic acid consumption, respectively, far higher than the 21.0% share of China.
In recent years, the rapid development of China's shoe sole material and polyurethane slurry market has prompted the rapid expansion of polyurethane raw material devices, and will continue to grow rapidly in the future, which will greatly stimulate the growth of adipic acid consumption. China's nylon production equipment is limited, and the scale of nylon equipment is relatively large. It is impossible to completely rely on imported products to meet the production demand of the equipment. Therefore, few domestic companies use imported adipic acid to produce nylon, and the main nylon production equipment is self-supporting. Acid devices are mostly imported in the form of imported nylon fibers and resins to meet the rapidly growing market demand.
The oversupply of production capacity will change the supply pattern With the steady development of China’s national economic construction, the demand for adipic acid will continue to grow rapidly in the next few years. The specific performance is as follows: The demand for production of polyurethane raw material polyester polyols is increasing and is expected to increase at a rate of 10% to 15% per year; the demand for adipic acid for the production of nylon 66 salt will also increase, but for adipic acid Pulling is limited; adipic acid ester plasticizers are important additives for plastics processing, such as dioctyl adipate. Such plasticizers have the characteristics of cold resistance, oil resistance, water resistance and durability, and have permanent plasticizers. It is said that the application prospect is good; a small amount of adipic acid is also needed in the production of unsaturated polyester resin. In addition, adipic acid can also produce ammonium adipate, adipic acid monoesters and other products for the electronics industry (capacitor production).
In 2012, China's demand for adipic acid is about 650,000 tons, and the production capacity will reach 915 thousand tons per year. According to the operating rate of 70%, the output will reach 640,000 tons. Therefore, the self-sufficiency rate of adipic acid in China will be greatly increased, and there will be excess supply, and market competition will further intensify.
In the coming years, the pattern of suppliers of adipic acid in China will undergo major changes. Liaoyang Petrochemical Company's adipic acid production capacity currently accounts for approximately 40% of the domestic market. With the launch of the new 160,000-ton/year plant, its production capacity will reach 300,000 tons/year, making it Asia's largest adipic acid producer. Liaohe will gradually expand its sales to end customers and gradually eliminate distributors.
At the same time, Liaohua has been improving the quality of its own adipic acid products and is actively seeking export channels to pave the way for new capacity. In the next few years, Liaohua is still one of the largest suppliers of adipic acid in China. Its proportion of direct sales of products will increase. At the same time, it will open up the export road and open up the export channels of Japan, South Korea and Southeast Asia, and even possibly to the Middle East. And European exports.
In addition, PetroChina Dushanzi Petrochemical Company, Shandong Hongye Chemical Industry and Ningbo Bohui Petrochemical Company will become new suppliers of adipic acid. From the perspective of market sales, the adipic acid products of these three companies will firstly target the polyurethane market. In 2012, the supply of adipic acid in the Chinese market will be dominated by domestically produced goods, and the self-sufficiency rate of the products can reach more than 90%, basically ending the history that China's adipic acid needs a lot of imports.
Accelerating the development of new technologies Promoting the integrated development of upstream and downstream As China's new production capacity of adipic acid continues to increase, the situation of oversupply is being formed, and competition in the future will become more intense.
At present, the production of adipic acid in China mainly adopts the oxidation method, which has a greater impact on the environment. With the further implementation of energy-saving and emission-reduction measures and people's further improvement of environmental protection requirements, China's adipic acid production enterprises will also face energy-saving and reduction. Rows of challenges. Under this background, technological research and development efforts should be intensified to reduce the discharge of acid-containing wastewater and greenhouse gas in the production of adipic acid, so as to reduce the adverse impact on the environment and increase the economic efficiency of enterprises.
In order to upgrade the quality of adipic acid products, reduce production costs, and reduce environmental pollution through technological transformation, it is necessary to accelerate the development of new synthetic technologies, especially green synthesis of adipic acid with cyclohexene and hydrogen peroxide. The use of biotechnology in the synthesis of adipic acid technology development, in order to promote technological progress, as soon as possible to shorten the gap between China's adipic acid and international standards, enhance international competitiveness.
At present, China's relevant manufacturing enterprises only produce adipic acid or only produce a single downstream product. It is difficult to obtain greater profits in the fierce market competition and the living space is limited. It is necessary to accelerate the development and production of downstream products, form a scale of upstream products, diversify, serialize, and refine downstream products, increase overall device competitiveness, and actively expand exports to promote rapid and healthy development of the entire industry.
Adipic acid, also known as Adipic Acid (abbreviated as AA), is one of the most useful dicarboxylic acids in aliphatic dicarboxylic acids. It is mainly used in the production of nylon 66 and nylon 66 engineering plastics, polyurethane foams and Plasticizers can also be used for the production of advanced lubricants, food additives, pharmaceutical intermediates, perfume flavor control agents, new single crystal materials, plastic foaming agents, paints, insecticides, adhesives, and dyes.
