The Main Types Of Intermediates

Intermediates refer to semi-finished products, which are intermediate products in the production of certain products, such as to produce a product, which can be produced from intermediates to save costs.
Intermediates are formed by cyclic compounds such as benzene, naphthalene, anthracene, etc. by sulfonation, alkali melting, nitrification, reduction and other reactions. For example, benzene is nitrified into nitrobenzene, and then reduced to aniline, which can be chemically processed into dyes, drugs, vulcanization accelerators, etc. Nitrobenzene and aniline are intermediates.
It is also formed by the reaction of acyclic compounds such as methane, acetylene, propylene, butane, butene, etc. by dehydrogenation, polymerization, halogenation, hydrolysis, etc. For example, butane or butene is dehydrogenated into butadiene, and butadiene can be chemically processed into synthetic rubber, synthetic fiber, etc. Butadiene is an intermediate.
Originally refers to the intermediate products produced in the process of synthesizing chemical products such as fragrances, dyes, resins, drugs, plasticizers, rubber accelerators and other chemical products using coal tar or petroleum products as raw materials. It now refers to various intermediate products obtained in the process of organic synthesis.
