Introduction To Intermediates

- Jan 03, 2019-

Intermediates refer to Semi-finished products, which are the products that produce the middle of a certain product, such as the production of a product that can be produced from intermediates and save costs. Intermediates are composed of annular compounds such as benzene, naphthalene, anthracene and so on by sulfonation, alkali melting, nitrification, reduction and other reactions. For example, benzene by nitrification into nitrobenzene, and then reduced to aniline, aniline can be chemically processed into dyes, drugs, vulcanization accelerator and so on. Both Nitrobenzene and aniline are intermediates.
