Type Of Intermediate

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