Fine chemical industry is a highly comprehensive technology-intensive industry. First of all, in the production process, the process flow is long, the unit reactions are many, the raw materials are complex, the intermediate process control requirements are strict, and the application involves multi-field, multi-disciplinary theoretical knowledge and professional skills, including multi-step synthesis, separation technology, analysis and testing, and performance. Screening, compounding technology, formulation development, commercial processing, application development and technical services, etc. Fine chemical industry is one of the most dynamic emerging fields in the chemical industry today and an important part of new materials. There are many types of fine chemical products, high added value, wide use, and large industrial relevance, which directly serve many industries in the national economy and various fields of high-tech industries.

Fine chemical products include the following 11 product categories: 1. Pesticides; 2. Dyes; 3. Coatings (including paints and inks); 4. Pigment; 5. Reagents and high purity materials; 6. Information chemicals (including photosensitive materials, magnetic materials and other chemicals that can receive electric waves); 7. Food and feed additives; 8, adhesives; 9. Catalysts and various additives; 10. Chemicals (raw materials) and daily chemicals produced by the chemical system. 11. Functional high molecular materials in high molecular polymers (including functional films, polarizing materials, etc.).

There are many types of fine chemicals, including inorganic compounds, organic compounds, polymers and their complexes. The common characteristics of production technology are: 1. There are many varieties and rapid updates, and the need for continuous product technology development and application development, so research and development costs are very high, such as medical research funds, which often account for 8% of drug sales. ~10%. This leads to strong technological monopoly and high sales profit margins. 2. The product quality is stable, and the original product requires high purity. After the compounding, not only the physical and chemical indicators must be guaranteed, but also the use performance must be paid more attention to. It is often necessary to equip a variety of testing methods for various use tests. These tests have long periods and complex equipment. Many test items involve human safety and environmental impact. Therefore, there are many regulations and standards for the management of fine chemical products. 3. The production process of fine chemical industry is different from general chemical production. The whole production process includes not only chemical synthesis (or separation and extraction from natural substances), but also formulation processing and commercialization. 4. Most of them are produced in batches in small batches. 5. The product has strong commercial nature and fierce competition among users. Research and production units must have comprehensive application technologies to provide users with technical services.

The development of fine chemicals is of great significance: it has promoted the improvement of the clothing, food, transportation and use levels of other industries such as agriculture, medicine, textile printing and dyeing, leather, papermaking, etc., and at the same time has brought about the improvement of economic benefits for these industries; for biotechnology , Information technology, new materials, new energy technology, environmental protection and other high-tech developments provide a guarantee; ensure and promote the development of the petroleum and chemical industry; increase the processing depth of the chemical industry, and increase the The economic benefits of the company; it has improved the overall economic benefits of the country’s chemical industry and strengthened the country’s economic strength.
