Introduction of chemical intermediates
2023-05-06 14:44
Chemical intermediates are an important basis for the production of fine chemical products. The rapid development of the global fine chemical industry has driven the growth of demand for the global chemical intermediate industry and the advancement of production technology. Fine chemicals are divided into pesticides, dyes, coatings, pigments, reagents and high-purity substances, information chemicals, food and feed additives, adhesives, catalysts and famous seed additives, chemicals and daily chemicals, polymers There are 11 major categories such as functional polymers in polymers. China refers to the raw materials and intermediates for the production of the above 11 categories of fine chemicals as chemical intermediates.
Organic chemical intermediates are the downstream products of basic raw materials (triene, triphenyl, acetylene, naphthalene, etc.) and important organic raw materials, and are also important raw materials for the production of fine chemical products. effect.
In terms of market structure, according to calculations, the market size of my country's chemical intermediates and traditional Chinese medicine intermediates currently accounts for a large proportion, reaching 45%, the market size of pesticide intermediates accounts for 28%, and the market size of dye/pigment intermediates accounts for 3%. , other types of chemical intermediates accounted for 24%.
With the development of science and technology, the development and application fields of fine chemicals will continue to expand, and new categories will continue to increase.
Fine chemicals have the following characteristics:
(1) There are a wide variety 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 medicine, dyes, pesticides, coatings, daily chemicals, electronic materials, paper chemicals, inks, food additives, feed additives, water treatment, etc., also in aerospace, biotechnology, It is widely used in high-tech fields such as information technology, new materials, new energy technology, and environmental protection.
(2) Complex production technology
There are many kinds 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 complicated. All kinds of fine chemical products need to go through laboratory development, small test, pilot test and then large-scale production. They also need to be updated or improved in time according to the changes in the needs of downstream customers. The requirements for product quality and stability are relatively high. Continuously improve the process and accumulate experience in the process. Therefore, the derivative development of fine chemical products in subdivided fields, the accumulation of experience in production technology 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 it needs to go through multiple multi-unit operations. Easy separation and high product yield require high-level process technology and reaction equipment. Therefore, fine chemical products generally have higher added value.
(4) There are many types of compound products
In practical application, fine chemicals appear with the comprehensive functions of products, which requires screening of different chemical structures in chemical synthesis, and giving full play to the synergistic cooperation between the functions of fine chemicals and other complex substances in the production of dosage forms. The demand for fine chemical products in industrial production is diverse, and a single product is difficult to meet the needs of production or use. Taking the water treatment industry in which the company is located as an example, the special chemicals used in this field include bactericides and algaecides, inhibitors Scaling agents, corrosion inhibitors, flocculants, etc., and the chemical preparations for each purpose can be compounded by several chemical agents.
(5) The product has a high viscosity to downstream customers
Fine chemical products are generally used in specific areas of industrial production processes or to achieve specific functions of downstream products. Therefore, users have higher requirements for product quality and stability, and stricter supplier selection processes and standards. Once entered into the supplier list, they will Will not be replaced easily.
With the continuous development and development of fine chemicals, the market demand for chemical intermediates is also increasing, which will continue to bring new opportunities and challenges to chemical intermediate companies. Chemical intermediate companies also need to continue to follow the trend of the market. Actively explore, develop and innovate.
