In recent years, various countries around the world, especially industrialized developed countries, have regarded the development of fine chemical products as one of the key development strategies for the structural upgrading and adjustment of traditional chemical industries, and their chemical industries have developed in the direction of “diversification” and “refinement”. With the further development of the social economy, people’s demand for electronics, automobiles, machinery industry, new construction materials, new energy and new environmental protection materials will further increase. Electronics and information chemicals, surface engineering chemicals, pharmaceutical chemicals, etc. With further development, the global fine chemicals market will maintain a faster growth rate than the traditional chemical industry.
*Fine chemicals
Fine chemicals refer to chemicals with high technical density, high added value and high purity that can enhance or endow a product (type) with specific functions or have specific functions in small batch manufacturing and application, and are further basic chemicals. The product of deep processing.
In 1986, the former Ministry of Chemical Industry divided fine chemical products into 11 categories: (1) pesticides; (2) dyes; (3) coatings (including paints and inks); (4) pigments; (5) reagents and high-purity substances (6) Information chemicals (including photosensitive materials, magnetic materials and other chemicals that can receive electromagnetic 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 polymer materials in polymer polymers (including functional films, polarizing materials, etc.). With the development of the national economy, the development and application of fine chemicals will continue to expand, and new categories will continue to increase.
Fine chemicals have the following characteristics:
(1) A wide variety of products and a wide range of applications
There are 40-50 categories of fine chemicals internationally, with more than 100,000 varieties. Fine chemicals are used in all aspects of daily life, such as medicine, dyes, pesticides, coatings, daily chemical supplies, electronic materials, paper chemicals, inks, food additives, feed additives, water treatment, etc., as well as in aerospace, biotechnology, Information technology, new materials, new energy technology, environmental protection and other high-tech applications 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 for different purposes through different processes. The production process is complex and changeable, and the technology is complicated. All kinds of fine chemical products need to undergo laboratory development, 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. The product quality stability requirements are high, and the company needs to produce Continuously improve the process and accumulate experience in the process. Therefore, the derivative development of fine chemical products in subdivisions, the accumulation of experience in production processes and the ability to innovate are the core competitiveness of a fine chemical enterprise.
(3) High added value of products
The production process involved in fine chemical products is relatively long and requires multiple multi-unit operations. The manufacturing process is relatively complicated. The production process meets mild reaction conditions, safe operating environment, and specific chemical reactions to achieve chemical Easy separation and high product yield require high-level process technology and reaction equipment. Therefore, fine chemical products generally have higher added value.
(4) Variety of compound products
In practical applications, fine chemicals appear as the comprehensive functions of products. This requires screening of different chemical structures in chemical synthesis, and fully exerting the synergistic cooperation of fine chemicals with other compounds in the production of dosage forms. There are various demands for fine chemical products in industrial production, and it is difficult for a single product to meet the needs of production or use. Take the water treatment industry where the company is located as an example. Special chemicals used in this field include fungicides and algaecides, Scale agents, corrosion inhibitors, flocculants, etc., and the chemical agents for each purpose can be compounded by several chemical agents.
(5) The product has high viscosity to downstream customers
Fine chemical products are generally used in specific areas of the industrial production process or to achieve specific functions of downstream products. Therefore, users have higher requirements for product quality and stability, and the supplier selection process and standards are more stringent. Once entered the supplier list, Will not be easily replaced.
