China is a major producer of fine chemicals and also a major exporter. After half a century of development, there are nearly 25 categories, more than 30,000 kinds of products, annual output of about 1,500 billion yuan, and including technology development, intermediate production, synthesis, preparation, compounding and technical services, processing more complete industrial system. But technological level is not high, is still the restricting bottlenecks of China's fine chemical development.
Although the Chinese self-developed a number of internationally advanced level of fine chemicals, such as citric acid, xanthan gum, sorbic acid, long chain dicarboxylic acid, itaconic acid, hyaluronic acid, biological polyacrylamide, polypropylene catalyst has been among the international market. However, the level of backward technology and equipment result in the development of China's fine chemical is far lower than developed countries. Many domestic enterprises device or workshops, in the process route, unit operations, product handling and other aspects still remain in the level of the 1970s, the level of automation, application development and technical services to keep up. In some new areas of development, such as hydrogenation, Copper Chromite(CC), continuous nitration, adiabatic nitration, the liquid sulfur trioxide sulfonation, functional polymer materials, fine ceramics, LCD, information products, such as nano-materials is still very weak, or just getting started.
The rate of fine chemicals has become a measure of a country or region chemical development of the main signs. As the petrochemical and basic chemical profit margins shrink, more and more developed countries, and the core of a large petrochemical industry will shift to the direction of fine chemicals, and intended to biotechnology, new materials, new energy technologies as a leader to seize the high ground of the future primary means. Although China from 'sixty-five' start, after 20 years of development, the construction of a large number of fine chemicals plant, built a number of fine chemical industry base, or park, fine chemical rate has reached 48%, but there is still great compared with other countries the gap. According to statistics, the U.S. DuPont fine chemicals business has accounted for 60% of sales; the Swiss company Ciba fine production of fine chemicals and other professional companies, fine chemical sales total sales 80% -90%; Germany BASF, Hoechst and Bayer chemical company and three British chemical company ICI will be fine as a key development, the rise significantly. Some developing countries are to accelerate the development of basic petrochemical industry, Musk R-1 while speeding up the introduction of advanced Western technology to transform the traditional chemical production, and construction of large-scale multi attract foreign investment, advanced chemical production plant.
International trends show that the development of fine chemicals, scientific and technological competition will be intensified, a worldwide restructuring will be inevitable. This trend must be accelerated to promote China's fine chemical technology catch-up, efforts to narrow the gap with developed countries.
In traditional areas, to strengthen the existing products deep processing, the development of surface-treated, high-purity, single crystal, and micro and nano-scale products. Such as high-grade coatings industry to solve the key raw material used in paint at the same time, vigorously develop energy-saving, environmentally friendly and durable paint, water paint, powder coatings, radiation curable coatings, organic silicon, organic fluorine modified acrylic paint, heavy-duty coatings and special coatings and other special features. Dye industry focus on developing environmental regulatory requirements in line with international textile disperse dyes, Triphenyl Bismuth, reactive dyes, acid dyes, direct dyes and pigments harmful alternative products.
In the new field of promising to do a good job, have an important role in supporting the national economy, the shortage of large wide product development. Focus on feed additives in methionine, lysine, calcium pantothenate, vitamins (E, A, D), propionic acid and defluorinated phosphate; food additives in the L-lactic acid, sorbic acid, nucleic acids, fat and security sugar substitutes; paper chemicals in the emulsion rosin, AKD, EDTA; high molecular weight polyacrylamide flocculant and other natural or semi-natural; bio-chemical products in the new enzymes, new biodegradable polymer materials, long chain dicarboxylic acids, the new bio-pesticide.
