Fine chemical industry is a technology-intensive industry with strong comprehensiveness. Firstly, in the production process, the process flow is long, the unit reaction is many, the raw material is complex, the intermediate process control is strict, and the application and involves many fields. Fine chemical industry is one of the most vigorous new fields in chemical industry, and it is an important part of new materials. Fine chemical products have many kinds, high added value, wide uses and large industrial linkages, which directly serve many industries of national economy and various fields of high-tech industries. To vigorously develop fine chemicals has become a strategic focus for countries all over the world to adjust the structure of chemical industry, upgrade the energy level of a chemical industry and expand economic benefits. In order to promote the optimization and upgrading of the national fine chemical industry structure and enhance the overall competitiveness of the industry, the state timely promulgates relevant policies and establishes a new type of technological innovation organization - the national strategic alliance for technological innovation of fine chemical industry, which combines industry, education and research. The rate of fine chemical industry (the proportion of fine chemical output value to total chemical output value) has become an important symbol to measure the level of chemical industry development and scientific and technological level of a country or region.
