Chemical intermediates is an important basis for the production of fine chemical products. The rapid development of the global fine chemical industry drives the growth of the demand of the global chemical intermediates industry and the progress of production technology. Fine chemicals are divided into 11 categories: pesticides, dyes, coatings, pigments, reagents and high purity substances, information chemicals, food and feed additives, adhesives, catalysts and famous additives, chemicals and daily chemicals, and functional polymers in polymer polymers. China collectively 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. They are also important raw materials for the production of fine chemical products. They play a very important role in the production and development of chemical industry.
In terms of market structure, it is estimated that at present, the market scale of chemical intermediates, traditional Chinese medicine intermediates, pesticide intermediates, dye / pigment intermediates and other types of chemical intermediates in China account for 45%, 28%, 3% and 24%, respectively.
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 many kinds of products and a wide range of applications
There are 40-50 categories and more than 100000 varieties of fine chemicals in the world. Fine chemicals are used in all aspects of daily life, such as medicine, dyes, pesticides, coatings, daily chemical products, electronic materials, papermaking chemicals, inks, food additives, feed additives, water treatment, etc. they are also widely used in aerospace, biotechnology, information technology, new materials, new energy technology, environmental protection and other high and new technologies.
(2) Complex production technology
There are many kinds of fine chemicals. The same intermediate product can extend several or even dozens of derivatives for different purposes through different process flows. The production process is complex and changeable, and the technology is complex. All kinds of fine chemical products need to go through laboratory development, small-scale test, pilot test and then large-scale production. They also need to be updated or improved in time according to the needs of downstream customers. They have high requirements for product quality stability. Enterprises need to constantly improve their processes and accumulate experience in the production process. Therefore, the core competitiveness of a fine chemical enterprise is the derivative development of fine chemical products in subdivided fields, the experience accumulation and innovation ability of production process.
(3) High added value of products
The production process of fine chemical products is long, which needs multiple and multi unit operations, and the manufacturing process is complex. In the production process, mild reaction conditions, safe operating environment, specific chemical reaction and other conditions are met to realize easy separation of chemicals and high product yield, which requires high-level process technology and reaction equipment. Therefore, fine chemical products generally have high added value.
(4) There are many types of compound products
In practical application, fine chemicals appear as the comprehensive function of products, which requires screening different chemical structures in chemical synthesis, giving full play to the function of fine chemicals and the cooperation with other cooperating substances in dosage form production. 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 where the company is located as an example, the special chemicals used in this field include bactericide and algaecide, scale inhibitor, corrosion inhibitor, flocculant, 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 industrial production process or to realize specific functions of downstream products. Therefore, users have high requirements for product quality and stability, and are strict with the supplier selection process and standards. Once they enter the supplier list, they will not be easily replaced.
With the continuous development and development of fine chemicals, the market demand for chemical intermediates is also growing, which will continue to bring new opportunities and challenges to chemical intermediates enterprises. Chemical intermediates enterprises also need to follow the trend of the market, actively explore, explore and innovate.
