Development status of fine chemicals at home and abroad

according to statistics, there are 17 chemical enterprises in the global top 500, among which the first few are DuPont, BASF, Hearst and Bayer, Dow in the United States and Ciba carkey in Switzerland. Both of them have a history of more than 100 years. Before the 1970s, they vigorously developed petrochemical industry, and then gradually turned to fine chemical industry. Germany is the first country to develop fine chemicals. They started from coal chemical industry. Before the 1950s, coal chemical industry accounted for about 80% of the raw materials. However, due to the poor process route and efficiency of coal chemical industry, the proportion of chemical products with petroleum as raw materials has soared to more than 80% since 1970

DuPont is the world's largest chemical company, founded in 1802. It changed from petrochemical industry to fine chemical industry by a large margin around 1980, which started later than Germany and Japan, but developed rapidly. Since the 1980s, the company has expanded the production of special chemicals, mainly fine chemical products such as pesticides, pharmaceuticals, special polymers, composite materials and so on. The long-term goal of the company is to develop life science products, such as health products, anti-cancer, anti-aging and other drugs and bionic medical products. In 1995, the profit of the company was $3.3 billion

Dow Chemical Company was founded in 1897. In the late 1970s, through the structural adjustment of products, the production of polymers for medicine and various engineering purposes was strengthened, especially in automotive coatings and adhesives. In 1973, the output value of fine chemicals of the company was only 540million US dollars, and the rate of fine chemicals was 18%, which soared to 50% in 1996. In the early 1990s, the total output value was 20billion US dollars, while the output value of fine chemicals accounted for 11billion US dollars

BASF, Hearst and Bayer are the three pillars of German chemical enterprises. Most of them use mergers, transfers and sales as means to increase investment, implement core businesses based on the strength of technical strength, and try to improve the proportion of core businesses and the market share of leading products. The development of high-tech fields such as health care and pharmaceutical products, agricultural chemicals, electronic chemicals, medical diagnostic products, information and imaging products, aerospace chemicals and new materials has greatly improved the scientific and technological content and economic benefits of fine chemical products. For example, the sales of several distinctive products such as BASF's coatings and photosensitive resins increased from 11% in 1980 to 30% in 1995. The company's turnover in 1994 was 46.2 billion marks, Hearst's turnover in 1996 was 52.1 billion marks, and Bayer's turnover in 1994 was 26.7 billion dollars. They all attach great importance to the development of high and new technology. By the end of 1995, Bayer company had obtained 155000 patents and 24000 products. Its leading product aspirin in medicine has a history of 100 years

Ciba Jiaji company in Switzerland is a world-famous manufacturer of pesticides, pharmaceuticals, dyes, additives, cosmetics, detergents, aerospace adhesives, etc. it is the only large enterprise in the world that develops fine chemicals by outsourcing all raw materials. In 1994, its turnover was 16.1 billion US dollars, and its fine chemical industry rate ranked first in the world, reaching more than 80%

developed countries continue to adjust the product structure of chemical industry according to the needs of economic benefits and development, as well as the guidance of market, environment and resources. The focus of their transition is on fine chemicals, and the development of fine chemicals has become a worldwide trend. In 1991, the worldwide sales of fine chemicals, such as the ferry construction industry, amounted to more than $40 billion, mainly in Western Europe, the United States and Japan. In the early 1990s, the rate of fine chemicals in developed countries was about 55%, while in the late 1990s, it rose to 60%. The development speed of fine chemicals has been higher than that of other industries. Taking the United States as an example, carbon fiber reinforced thermoplastic composites (CFRTP), which are prepared by combining the advantages of engineering plastics such as corrosion resistance, low specific gravity, impact resistance, easy molding, and can be used twice, had an industrial growth rate of 2.9% in the late 1980s, while fine chemicals were as high as 5%. The main goal of their development is to expand the production of College supplies, such as medical and health products, electronic chemicals, special polymers and composite materials, and vigorously develop related life science products, such as anti-cancer drugs, color changing coatings in the bionic medical automobile industry. The utilization income will reach 595million US dollars, pollution-free high-efficiency herbicides, fungicides and so on

since our country set fine chemical industry as the key development goal in the 1980s, it has been tilted in policy and developed rapidly

during the Eighth Five Year Plan period, 10 fine chemical technology development centers have been built, with an annual production capacity of more than 8million tons, about million product varieties, and an annual output value of 90billion yuan, which has laid a certain foundation. At the end of the 20th century, the rate of fine chemicals reached 35%. Compared with foreign developed countries, there is a big gap. They only need 16000 kinds of fine chemicals for the electronic industry, more than 7000 kinds of color TV sets, and the matching rate of domestic products is less than 20%, and the rest are imported. Other textile finishing agents, leather finishing agents and other aspects are more in short supply. In addition, the quality, variety, technical level, equipment and experience of China's fine chemical products can not meet the needs of many industries
