Fluorine-containing aromatic fluorinated fine chemicals and reagents technology iscutting-edge field of fine chemicals as well as constraining the development of domestic fine chemical industry bottlenecks. East China University of Science and Technology of fluorine-containing aromatic fluorinated fine chemicals and reagents of key technologies, theory and application and industrialization projects, broke through the bottleneck in organic fluorine chemical technology, fine chemical products for our technology laid the foundation for upgrading. The achievement in 2008 was awarded the second prize of national scientific and technological

progress.

China's resource-rich fluoride, accounting for 54% of the world's reserves, high value-added follow-up of fluorine chemical production has accounted for only 4% of the world. A wealth of resources and the depth behind the use of fluoride to form a great contrast of industrial technology, the impact in this area of our country's international competitiveness.

Fluorine-containing aromatic fine chemicals production difficulties in the production process of its impact factor of many, very sensitive to operating conditions, preparation of complex and difficult to master the technology, quality, yield difficult to ensure. Therefore, the fine tradition of fluorinated organic chemicals technology innovation, development of key generic fluoride and fluorine-containing aromatic fine block, fluorinated reagents technology industry imminent.

Since 1992, East China University of Science and Technology Vice-Chancellor Professor Qian Xuhong such conduct in-depth studies on this, and Shanghai Institute of Organic Chemistry, Chinese Academy of Sciences co-researchers, more than a decade after tireless research and in-depth study, for the

fluorine-containing aromatic Fine chemical production process of the different requirements of the reaction, put forward the innovative industry needed to achieve the response system, response equipment, as well as "three wastes" treatment, in the efficient production, to achieve the energy conservation, energy, emission reduction, environmental protection promoted the preparation of our fine aromatic fluoride technology and industry, scientific and technological progress.

Up to now, the project received a total of 18 invention patents, 47 published papers SCI. Fluorine-containing fine chemicals in the production, the technology was successfully applied to a variety of fluorine-containing aromatic fluorinated fine chemicals and industrial preparation of reagents and process optimization, product yield, improve quality, product technology and quality reached the international

advanced level, "waste" a significant decrease in resources to take full advantage of, economic and environmental benefits significantly.

Xu-Hong Qian told reporters that the project in the development process, the design was prepared by a wider applicability, the combination of higher activity of fluorosis fluoride salt phase transfer catalyst to shorten the reaction time, reduced the amount of potassium fluoride to improve the collection rate and quality; the establishment of a set of applicable to the industrialized production, simple, low-cost raw

material pre-treatment process, to effectively improve the reliability of the fluorination reaction, reproducibility and can be enlarged, and nhibit the occurrence of side effects significantly simplifies the

process of post-treatment increased the yield and quality of the product; design a new type of fluoride reactor in industrial applications in response to raise the efficiency of 1 / 3 or more.

In addition, the Task Force has also implemented so that return to natural fluoride residues of 'deposits' processing, greatly reduced the' waste to deal with the load; will be used in preparation of fluorine-containing block the development of new types of fluorine-containing compounds, developed promising application of fluoride metal reagents and preparation of fluorocarbon alcohol industry technologies; the development of a variety of functional structure of fluorine-containing fine chemicals, the promotion of the domestic scientific and technological progress in the field.

It is reported that fluorine-containing block the project, fluorination reagents and application development has also made an important breakthrough, research and development of high-performance fluorocarbon alcohol for many years to break the monopoly of foreign companies. East China University of Science using the structure of the fluoride-rich aromatic compounds, in the new fluorine-containing medicine, pesticide research and new progress was made. Zhejiang New Century Company, Jiangsu庙桥Chemical Company, Division of Hill Co., Ltd. have been jointly use of the technology, the success of the production of fluorine-containing aromatic fine chemicals. To date, the technology for these companies to create 258 million yuan of profits, the achievementof 11.07 million U.S. dollars export.
