Chinese has rich fluoride resources, accounting for 54 percent of world reserves. But the subsequent high value-added fluorine chemicals only account 4% of world production.

There is a huge contrast between rich fluorine resource and backward depth fluorine industrial technology. It affects China’s international competitiveness in the field.

Fluorinated aromatic fine chemicals production,Fluorine fine chemicals accelerates upgrade in China  Articles the impact factor of many difficulties in its production process, operating conditions is very sensitive to preparation techniques are complex and difficult to grasp, quality, yield is difficult to guarantee. Therefore, the traditional fine organic chemicals, fluoride technology innovation, development of generic key fine aromatic fluoride and fluorine-containing block, the industrial technology of fluorinated reagents imminent.

Since 1992, China began in-depth study on this conducts. After ten years of in-depth research and tireless research, different requirements on the reaction of fluorine- containing aromatic fine chemicals musk R-1 production process and put forward innovative necessary to realize the industrialization of the reaction system, reaction equipment as well as the three wastes treatment program in the efficient production at the same time, to achieve energy saving, emission reduction, environmental protection, promote the fine aromatic fluoride preparation technology and industry scientific and technological progress.

Up to now, the project won 18 Chinese invention patents and published 47 SCI papers. Fluorine-containing fine chemicals production, the technical achievements have been successfully applied to a variety of fluorinated aromatic fine chemicals and industrial preparation of fluorinated reagents and process optimization, so that the yield of the product quality can be significantly improved, product technology and quality reached the international advanced level, the three wastes significantly reduced the resources to take full advantage of significant economic and environmental benefits.

In the development process, the project design was prepared by a broader applicability and activity of a higher combination of fluoride phase transfer catalyst, shorter reaction time, reducing the amount of potassium fluoride to improve the yield and quality; established sets for industrial fine chemicals suppliers. There are simple, feasible and low-cost raw material pretreatment process to effectively improve the reliability of the fluorination reaction, reproducibility, and to zoom in, inhibit the occurrence of side reactions, significantly simplifies the handling process improve the yield and quality of the product; design and application of new fluoride reactor, more than 1/3 to improve the reaction efficiency in industrial applications.

In addition, the implementation of the residual fluoride ions to return to natural mineral processing, greatly reduces the processing load of the "three wastes"; used in preparation of the fluorine-containing block to the development of a wide range of new fluorinated compounds, development of the developed application prospect industrial preparation of metallized fluorinated reagents and fluorocarbon alcohol technology; to develop the structure of a variety of functions of fluorine-containing fine chemicals, and promote scientific and technological progress in the field.

At the same time, the development and application of the project in fluorinated building blocks and reagents fluoride has also made an important breakthrough. The efficient fluorocarbon alcohol breaks the monopoly of foreign companies for many years. Using these fluorine aromatic compounds with many structures China has made new progress in the field of new fluorine-containing pharmaceuticals and pesticides. Many Chinese companies have been used the technology. It brings the successful production of fluorine-containing aromatic fine chemicals. So far, the technology creates a profit of RMB 258 million for these companies. The export value is $ 11,070,000.Source:http://www.mhcfm.com
