What are the fine chemicals?
According to national conditions, China will be fine chemicals into pesticides, dyes, coatings, pigments, reagents and high purity materials, information chemicals, food and feed additives, adhesives, catalysts and various additives, chemicals and daily Chemicals, polymer polymers in the functional polymer materials 11 categories. The catalyst includes oil refining, petrochemical, organic chemical, synthetic ammonia, sulfuric acid, environmental protection catalyst and other catalyst, additives including auxiliaries, plastic additives, rubber chemicals, water treatment chemicals, fiber spinning oil, organic Extractants, high in the polymer additives, surfactants, leather chemicals, pesticide additives, oilfield chemicals, concrete admixtures, mechanical and metallurgical additives, oil additives, carbon black, adsorbent, electronic Chemicals, paper chemicals and glass mildew and latex coagulants and other additives.
Fine chemicals are widely used in all walks of life of the national economy. They have played an important role in improving quality, saving energy, reducing consumption, increasing production, improving and improving people's life. It is the focus and hotspot of the development of the world. And even the beginning of the next century, as China's large and medium-sized enterprises to adjust the product structure of the important measures, as one of the development strategy. Especially as one of the ways to improve the comprehensive utilization of China's petrochemical, coal chemical industry, natural gas chemical industry, salt chemical industry and agricultural and sideline products, and increase the ability of export promotion and improve economic efficiency. At present, fine chemical industry in China has formed a certain strength of the industry, fine chemical industry accounted for the proportion of total chemical output (refined rate) has reached 40% (chemical system for 32%). To 2000, will be further increased to 50% (45% of the chemical system).
Protection of intellectual property rights is a prominent issue in the development of fine chemicals, fine chemicals development, production and sales from the perspective of intellectual property to consider its technical and legal status, improve intellectual property awareness and protection capabilities to prevent infringement incidents. The fundamental solution is to improve the development of fine chemicals and technology investment, research and application of research and funding should be much more than 1.5% of sales; by molecular design and complex theory and scientific development procedures to take the the way.
The production of fine chemicals is not the same as that of general chemicals. It is mainly composed of chemical or biosynthesis, but also from the natural material separation, extraction; preparation processing; commercialization and other three parts. Most of the use of flexible and versatile devices and intermittent production. Synthetic products require a high purity, must be highly efficient synthesis or modification methods, complex refining measures, precision engineering. From the preparation to the commercialization of the need for a complex process, mainly based on market and user needs for complex. Therefore, the fine chemicals and their production methods (fine chemicals) with high technology-intensive, confidentiality and merchandise, the characteristics of fierce market competition. Generally can be in the form of product trees (derivatives) the development of fine chemicals; according to equipment and special technology development of fine chemicals; comprehensive utilization of waste from the development of fine chemicals; from the post-processing to develop fine chemicals. But will do more varieties and serial production, only with the ability to adapt to changes in market needs. Not only to make the product quality and stability, but also in line with various laws and regulations. Do a good job in applied research, technical services, marketing, in order to expand sales, reflecting the less investment, access to higher profit margins and the added value rate of the advantages.
Europe and the United States in some countries to produce small, clear composition, high purity, according to the specifications for small batch production and small packaging sales of chemicals known as fine chemicals; the production of small, modified or complex processing, with multi-functional or Dedicated functions, both according to their specifications, but also according to their use of small batch production and small packaging sales of chemicals known as special chemicals. China and Japan to the above two chemicals collectively referred to as fine chemicals.
