Interpretation of fine chemical industry

Characteristics of fine chemicals

(1) A wide range of products and a wide range of applications

There are 40-50 categories of fine chemicals in the world, with more than 100,000 varieties. Fine chemicals are used in all aspects of daily life, such as medicines, dyes, pesticides, paints, daily necessities, electronic materials, paper chemicals, inks, food additives, feed additives, water treatment, etc., also in aerospace, biotechnology, Information technology, new materials, new energy technology, environmental protection and other high-tech aspects are widely used.

(2) Complex production technology

There are many varieties of fine chemicals, and the same intermediate product can be extended to several or even dozens of derivatives with different uses through different technological processes. The production process is complex and changeable, and the technology is complex. All kinds of fine chemical products need to be developed in the laboratory, small test, pilot test and then to large-scale production. They also need to be updated or improved in time according to the changes in the needs of downstream customers. They have high requirements for product quality stability and require enterprises to produce Continuously improve the process during the process and accumulate experience. Therefore, the enterprise's derivative development of fine chemical products in subdivided fields, accumulation of experience in production processes and innovative capabilities are the core competitiveness of a fine chemical enterprise.

(3) High value-added products

The production process involved in fine chemical products is long, and it requires multiple multi-unit operations. The manufacturing process is relatively complicated. During the production process, mild reaction conditions, a safe operating environment, and specific chemical reactions are required to achieve chemicals. It is easy to separate and the product yield is high, which requires a high level of process technology and reaction equipment. Therefore, fine chemical products generally have higher added value.

(4) There are many types of compound products

In practical applications, fine chemicals appear as comprehensive functions of products. This requires screening different chemical structures in chemical synthesis, and fully exerting the functions of fine chemicals in the production of dosage forms in collaboration with other complex substances. The demand for fine chemical products in industrial production is diverse, and it is difficult for a single product to meet the needs of production or use. Taking the company's water treatment industry as an example, the special chemicals used in this field include sterilization and algaecide Scale agent, corrosion inhibitor, flocculant, etc., and the chemical preparation for each purpose can be compounded by several chemical agents.

1. Divided by application field

According to the national economic classification standards, fine chemicals are divided into four sub-sectors: pesticide manufacturing, paint, ink, pigment and similar product manufacturing, special chemical product manufacturing and daily chemical product manufacturing.

2. By product category

With the rapid development of my country's economy and technology after the reform and opening up, my country's fine chemical industry has developed rapidly. According to product categories, it can be divided into two parts: traditional fields and emerging fields.

(1) Traditional fields of fine chemical industry

The traditional fields of the fine chemical industry mainly include pesticides, fertilizers, and coatings. After a long period of accumulation, my country's fine chemical industry has basically met the needs of national economic development in the traditional field. Some products have achieved certain international competitiveness. The output of dyes and pesticides has ranked first in the world, and the output of coatings has reached fourth in the world.

(2) Emerging fields of fine chemical industry

Fine chemical products in emerging fields are characterized by strong specificity and high technical content. The main types include food additives, feed additives, adhesives, surfactants, papermaking chemicals, water treatment chemicals, electronic chemicals, etc. At present, the overall technical level of my country's fine chemical industry is still relatively low. Some emerging fields of fine chemical products still need to be imported in large quantities. The entire industry is in the development stage of optimization and upgrading. There is still much room for improvement in the emerging field of fine chemical industries.
