Intermediates refer to semi-finished products, which are intermediate products in the production of certain products. For example, to produce a product, it can be produced from the intermediate to save costs.

Intermediates are formed from cyclic compounds such as benzene, naphthalene, anthracene through sulfonation, alkali melting, nitration, reduction and other reactions. For example, benzene is nitrated to nitrobenzene and then reduced to aniline, which can be chemically processed into dyes, medicines, vulcanizing agents, etc. Nitrobenzene and aniline are intermediates.
It is also formed by dehydrogenation, polymerization, halogenation, hydrolysis and other reactions of acyclic compounds such as methane, acetylene, propylene, butane, butene, etc. For example, butane or butene is dehydrogenated to butadiene, and butadiene can be chemically processed into synthetic rubber, synthetic fiber, etc. Butadiene is an intermediate.
It refers to the intermediate products produced in the process of synthesizing chemical products such as spices, dyes, resins, chemicals, plasticizers, rubber agents, etc. with coal tar or petroleum products as raw materials. Now it generally refers to various intermediate products obtained in the process of organic synthesis.
