Development trend and future of fine chemicals

It is the floorboard of fine chemicals industry, referred to as "fine chemicals". It can be summarized as: medicine, pesticides, synthetic dyes, organic pigments, paints, perfumes and essences, cosmetics and toiletries, soaps and synthetic detergents, surfactants, printing inks and their auxiliaries, adhesives, photosensitive materials, magnetic materials, catalysts, reagents, water treatment agents and polymer flocculants, papermaking auxiliaries, leather auxiliaries, synthetic material auxiliaries, textile printing and dyeing agents and finishing agents, food additives and feed additives. Petroleum additives and refining AIDS, cement additives, mineral flotation agents, casting chemicals, metal surface treatment agents, synthetic lubricating oil and lubricating oil additives, automotive chemicals, aromatic deodorants, industrial fungicides, electronic chemicals and materials, functional polymer materials, biochemical products and other more than 40 industries and categories. With the development of national economy, the development and application fields of fine chemicals will be continuously explored and new categories will be continuously increased.

With the development of high and new technologies in the world and China, nanotechnology, information technology, modern biotechnology, modern separation technology, green chemistry and many other high and new technologies will be combined with fine chemical industry to serve high and new technologies. High and new technologies will further transform fine chemical industry, further broaden the application fields of fine chemical products, further upgrade, refine, compound and functionalize products, and develop in the direction of high and new fine chemical industry. Therefore, the benign interaction of various high technologies is the fourth good opportunity for fine chemical industry.

Faced with these four good opportunities, it is no wonder that domestic experts, scholars and people of insight agree that fine chemical industry is definitely a sunrise industry in China with a bright future.

The progress of the industry and the development of enterprises need the support of outstanding professionals. This provides a place for our students to display their talents. In fact, the annual employment rate of our fine chemical graduates is as high as 95%. Many fine chemical enterprises inside and outside the province came to our school to ask for the introduction or recruitment of fine chemical graduates. Because there are many fine chemical enterprises in society, the economic benefits of fine chemical enterprises are generally good, the export and domestic market potential of fine chemical products are huge, and the development prospects of fine chemical products are broad, so the social capacity of fine chemical graduates is very large. In the foreseeable future, there will be basically no employment problem.

[Edit this paragraph] Development direction of fine chemical industry

According to the regulations of the Organization for Economic Development and Cooperation (OECD), automobile, machinery, nonferrous metallurgy and chemical industry belong to medium-tech industries in terms of technology intensity. High-tech and its industries are specific fields determined by their high R&D content, such as aerospace, information industry and pharmacy. As a branch of chemical industry, fine chemical industry generally belongs to the category of medium technology, but as fine chemical industry, high-performance chemical new materials, medicine, biochemistry and so on have been identified as high-tech categories. 2 1 century is the era of knowledge economy, and a new technological revolution of three frontier sciences with bioengineering, information science and new material science as the main body is bound to have a great impact on the chemical industry. The development trend of traditional industries such as fine chemicals is bound to increase the intensity of technical knowledge and complement each other with high and new technologies.

1. the combination of nanotechnology and fine chemical industry

The so-called nanotechnology refers to the science and technology that studies the motion law and interaction of the system composed of substances with the size between 0. 1 ~ 100nm, as well as the possible technical problems in practical application. Nanotechnology is one of the important contents of the revolution of science and technology industry in 2 1 century. It is a comprehensive discipline that highly intersects with physics, chemistry, biology, materials science and electronics, including basic science with observation, analysis and research as the main line and technical science with nano-engineering and processing as the main line. Undeniably, nanotechnology is a complete system integrating scientific frontier and high technology. Nanotechnology mainly includes nano-electronics, nano-machinery and nano-materials. Just like microelectronics and computer technology in the 20th century, nanotechnology will be one of the brand-new technologies in the 20th century. Its research and application will surely bring a new technological revolution.

Nano-materials have many characteristics, such as quantum size effect, small size effect, surface effect and macroscopic quantum tunneling effect, which make nano-particles obviously superior to ordinary particles in thermomagnetism, light, sensitivity, surface stability, diffusion and sintering properties, mechanical properties, etc. Therefore, nano-materials are widely used in fine chemicals. Specific performance in the following aspects:

(1) Nano-polymers are used to make foams with high strength/weight ratio, transparent insulating materials, laser-doped transparent foams, high-strength fibers, high-surface adsorbents, ion exchange resins, filters, gels and porous electrodes.

(2) Nano-daily chemical nano-daily chemical and cosmetics, nano-pigments, nano-photographic films and nano-fine chemical materials will bring us to a colorful world. Recently, the research department of Kodak Company in the United States has successfully developed a new nano-powder with both pigment and molecular dye functions, which is expected to bring revolutionary changes to color images.

(3) Adhesive and sealant nano-SiO2 _ 2 has been added to adhesive and sealant as an additive abroad, which greatly improves the bonding effect of adhesive and the sealing performance of sealant. Its mechanism is that the surface of nano-silica is coated with a layer of organic material, which makes it hydrophilic. When it is added into sealant, the structure of silicon dioxide is rapidly formed, that is, nano-SiO _ 2 forms a network structure, which limits the flow of colloid, accelerates the curing speed, improves the bonding effect, and improves the sealing performance of adhesive due to its small particle size.

(4) Coatings Adding nano-SiO2 _ 2 into various coatings can improve its aging resistance, smoothness and strength, and the quality and grade of coatings will naturally upgrade. Nano-SiO2 _ 2 is a kind of anti-ultraviolet radiation (that is, anti-aging) material, and its tiny particles have a large specific surface area, which can quickly form a network structure when the coating is dried, and at the same time increase the strength and smoothness of the coating.
