What are the types of fine chemicals

Author:


Fine chemical products include the following 11 categories: pesticides, dyes, coatings (including paints and inks. Although paints and printing inks have some commonalities, their technical requirements differ greatly and can be divided into two categories), pigments, reagents, and high-purity products Chemicals used for information (including photosensitive materials, magnetic materials and other chemicals that can accept electromagnetic waves, food and feed additives (which can be subdivided into two categories: "food additives" and "veterinary drugs and feed additives"), adhesives, catalysts and various additives, chemical synthetic drugs (raw materials) and daily chemicals, functional polymer materials in polymer polymers (including functional films, photosensitive materials, etc.). Among them, catalysts and various additives also include the following varieties:
1) Catalysts. Catalysts for refining, petrochemical, chemical industry, environmental protection (such as tail gas treatment), and other purposes.
2) Printing and dyeing auxiliaries. Detergent, dispersant, leveling agent, fixing agent, softener, antistatic agent, various pigment printing auxiliaries, fluorescent whitening agent, penetrant, cosolvent, defoamer, flame retardant for fiber, waterproof agent, etc.
3) Plastic additives. Plasticizers, stabilizers, lubricants, UV absorbers, foaming agents, coupling agents, flame retardants for plastics, etc.
4) Rubber additives. Vulcanizing agents, sulfur accelerators, anti-aging agents, plasticizers, re life agents, etc.
5) Water treatment agent. Flocculants, corrosion inhibitors, scale inhibitors and dispersants, bactericidal and algal killing agents, etc.
6) Oil used for fiber drawing. Polyester filament oiling agent, polyester staple oiling agent, nylon oiling agent, acrylic oiling agent, polypropylene oiling agent, vinylon oiling agent, and glass fiber oiling agent.

7) Organic extractant. Pyridone series, fatty hydrocarbon series, acetonitrile series, sugar aldehyde series, etc.
8) Polymer polymer additives. Initiating agent, polymerization inhibitor, terminator, regulator, activator.
9) Surfactants. Cationic, anionic, non ionic, and amphoteric surfactants other than household detergents.
10) Leather additives. Synthetic tanning agents, esterifying agents, finishing agents, brighteners, soft leather oils, etc.
11) Additives for pesticides. Emulsifiers, synergists, stabilizers, etc.
12) Chemicals used in oil fields. Chemicals used in mud, chemicals used in water treatment, demulsifiers used in oil fields, pour point depressants, etc.
13) Concrete additives. Water reducer, waterproof agent, accelerator, retarder, air entraining agent, foam agent, etc.
14) Additives for machinery and metallurgy. Rust inhibitors, cleaning agents, electroplating aids, welding aids, carburizing agents, nitriding agents, automotive and other vehicle antifreeze agents.
15) Oil additives. Disperse detergent additives, anti-wear additives, anti-oxidation additives, anti-corrosion additives, anti-static additives, viscosity regulating additives, pour point depressants, anti shock additives, hydraulic transmission additives, transformer oil additives, etc.
16) Carbon black. High wear resistance, semi reinforcing, pigment and other functional carbon black.
17) Absorbent protective agent. Rare earth molecular sieve series, alumina series, natural zeolite series, activated clay series
18) Special chemicals for electronic industry (excluding photoresist, dopant, MOS reagent and other high-purity substances and special gases) Potassium carbonate, fluoride, flux, graphite emulsion, etc. for kinescope.

19) Additives for paper. Sizing agents, reinforcing agents, retention aids, waterproofing agents, fabric additives, etc.
20) Other additives.
The above are the categories of fine chemical products of enterprises under the jurisdiction of the former Ministry of Chemical Industry. In addition, light industry, pharmaceutical and other systems also produce some other fine chemicals, such as pharmaceuticals, civil detergents, cosmetics, single and mixed fragrances, fine ceramics, life science materials, explosives and military chemicals, a wider range of electronic industry chemicals and functional polymer materials. In the future, with the development of science and technology, there will also be emerging categories of fine chemicals.
