Introduction to chemical reagents and fine chemicals

Fine chemical products refer to chemical products with high processing precision, high technology production, high purity and small batch production, such as reagents, medicine, spices, synthetic dyes and so on. But this is a general statement. With the development of fine chemical industry, people need a more specific and clear definition. To sum up all opinions, we can say that fine chemicals are chemical products with the following characteristics:

(1) Many varieties, fast replacement.

(2) The output is small, mostly in batch production.

(3) It has certain functionality. The so-called function refers to the chemical molecules through physical, chemical and biological effects to produce certain functions or effects. For example, ultraviolet absorbers, photosensitive materials, plasticizers and various other additives are fine chemicals that are physically functional; Antioxidants, fuel additives, etc., are fine chemicals that belong to chemical action or performance.

(4) Mostly hybrid products, formulations and other technologies determine product performance, and are sold under trade names.

(5) High technology intensity, requiring continuous technological development of new products and application technology research.

(6) The equipment investment scale is small and the additional output value is high.

Chemical reagents are referred to as reagents. It is a class of fine chemicals with various standard purities, used in teaching, scientific research, analytical testing, and can be used as alcohol and ultra-pure functional materials and raw materials required by some new industries.

The industry that produces fine chemicals is generally referred to as the fine chemical industry. The fine chemical industry was developed on the basis of the chemical reagent industry.
