Application Of The Kind Of Intermediate
Intermediate refers to semi-finished products, is the production of some product, such as the production of a product, can be produced from intermediates, cost savings.
Intermediates have a ring of compounds such as benzene, naphthalene, anthracene, such as sulfonated, alkali melting, nitrification, reduction and other reactions. For example, benzene through nitrification into nitrobenzene, and then restored to aniline, aniline can be chemically processed into dyes, pharmaceuticals, curing agents, etc. Nitrobenzene and aniline are intermediates.
There are also non-ring compounds such as methane, acetylene, propylene, butane, butene, such as dehydrogenation, polymerization, halogenated, hydrolysis and other reactions. For example, butane or butene by dehydrogenation of Cheng Ding butadiene, butadiene can be chemically processed into synthetic rubber, synthetic fibers, etc. Butadiene is an intermediate.
Originally refers to the production of the intermediate product of the chemical products such as spices, dyes, resins, pharmaceuticals, plasticizer, rubber promoter, etc., with coal tar or petroleum products as raw materials. Now refers to the organic synthesis process of the various intermediate products.
