Introduction to fine chemicals

The term fine chemicals, which has been used for a long time, originally refers to chemical products with small output, high purity and high price, such as medicine, dyes, coatings and so on. However, this implication does not fully reveal the nature of fine chemicals. In recent years, experts from various countries have some new ideas on the definition of fine chemicals. Some countries in Europe and the United States have called chemical substances with small production and sales according to different chemical structures fine chemicals. Products that are small in volume, processed and formulated, and have specialized functions or end-use properties are called specialty chemicals. China, Japan, etc., these two types of products are collectively referred to as fine chemicals.
