Accelerate industrial restructuring
In 2006, the production capacity of ethylene oxide in China reached 1.8 million tons and the volume of goods reached 500,000 tons. Although ethylene oxide is not directly imported without long-distance transport, the import volume of ethylene glycol derivatives ethylene glycol and various fine chemical products has shown rapid growth in recent years. In 2006, it reached 4.06 million tons, and imports were dependent on imports. Up to 72.3%.
China's current ethylene oxide is mainly used for the production of ethylene glycol and common non-ionic surfactants, of which about 70% for the production of ethylene glycol. Compared with developed countries, there are still large gaps in the structure, process technology and application fields of ethylene oxide-derived fine chemical products, especially in application fields and applied technologies. Many high value-added products still rely on imports. To this end, China's ethylene oxide industry should speed up the development of downstream refined chemical products, improve the level of technology and core competitiveness. Making full use of domestic resources and increasing the development and application of downstream fine chemical products can not only meet the development needs of related domestic industries, but also accelerate the adjustment of the consumption structure of ethylene oxide to form fine petrochemicals for downstream processing of ethylene oxide. Product clusters, access to higher economic efficiency, to ensure the healthy and stable development of China's ethylene oxide industry. According to China's development, research, production and application status, and drawing on foreign development models, China's ethylene oxide downstream fine chemical products should be processed in the following directions: ethylene oxide post-processed products ethoxylated compounds, ethanolamines, glycol ethers , Glyoxal, and other devices for the potential development of ethylene amines, piperazine, ethylene carbonate, hydroxyethyl compounds and other products, and the use of ethylene oxide and ethylene glycol as raw materials for 1,3-propanediol and 2 , 6-naphthalenedicarboxylate product research and development.
Form the advantages of industry, academia and research industry
To achieve industrial upgrading and technological innovation, the ethylene oxide industry needs to take enterprises as the center and mobilize the scientific and technological forces of the entire society to form the advantage of industry, university, and research industry. Taking the Aoke Group, a backbone enterprise of ethylene oxide derivative products in China, for example, Aoke has a number of technical applications such as the provincial-level enterprise technology center, the provincial-level ethylene oxide deep processing engineering technology center, and the post-doctoral scientific research base. platform. Over the years, Oak has combined its leading domestic core technologies and ethylene oxide derived products with special competitive advantages such as polyethylene glycol and national energy, environmental protection and health development needs, in polyethylene glycol, oilfield broken A series of important scientific research achievements and innovative applications have been made in the production process, process equipment, and variety development of special fine chemicals derived from ethylene oxide, such as emulsions and emulsifiers. More than a dozen scientific and technological achievements and new products have passed the provincial appraisal. There are 12 new technologies that have won national patents, and many of them have become national key new products and are listed in the National Spark Program, Torch Program, and Key Torch Program. At present, the production capacity of Oxyethylene oxide-derived fine chemical products has reached 80,000 tons/year, and the production capacity and sales volume have ranked the leading position in China, becoming China's highly competitive ethylene oxide deep processing industry base. .
Accelerating the urgent need of product innovation in the market
For domestic ethylene oxide enterprises, it is necessary to exert enthusiasm, improve old products, and upgrade new products. For example, photovoltaic crystalline silicon cutting fluid is a new green energy-related product and is an important material for photovoltaic solar cell utilization and generation of solar cells. According to statistics, by the end of 2003, China had installed a total of about 55MW of photovoltaic silicon cells, and it is expected to reach 30GW by 2020. However, photovoltaic crystalline silicon cutting fluid is one of the difficulties that hinder the development of photovoltaic silicon in China. Aoke Group exerted its advantages in scientific research and made unremitting efforts to develop photovoltaic silicon liquid cutting fluids with independent property rights instead of imports. While seizing the market opportunities, it also reduced the dependence on imports of photovoltaic silicon wafers for cutting and reducing Cost risks have created possibilities. After several years of development, the Group's photovoltaic crystalline silicon cutting fluid has occupied most of the domestic market. In July 2007, the company's "30,000 tons per year crystalline silicon cutting fluid project" was also approved by the National Development and Reform Commission and financial support.
In view of the current status of the ethylene oxide industry, Zhu Jianmin, deputy chairman of the China Fine Chemicals Industry Committee, suggested that relevant state departments and enterprises should attach great importance to and support the development of the ethylene oxide extension processing industry and seek to establish a country-led and enterprise-based organization. , a market-oriented, industry-research-research-combination technology innovation system, establishing strategic partnerships upstream and downstream of ethylene oxide, promoting a rational petrochemical industry structure, establishing a healthy and harmonious ethylene oxide extension industrial chain, and comprehensively advancing ethylene oxide The alkane industry is developing rapidly.
Ethylene oxide: urgent need to extend the industrial chain
China's ethylene oxide and its deep processing industry are currently in a stage of rapid development. The market for ethylene oxide-derived specialty chemicals is extremely broad. It not only facilitates the upgrading and transformation of traditional industrial technologies, but also stimulates the development and application of a series of high-tech achievements; it is not only widely used in civil washing, industrial cleaning, petrochemicals, Traditional fields such as metal processing, pesticides and medicine, textile printing and dyeing, rubber and plastics, and papermaking are increasingly used in cutting-edge fields such as nanotechnology and life sciences.
