Detailed introduction of the Intermediate API

Vitamins, disperse dyes, bleaches, emulsifiers,Intermediate API etc. These are collectively referred to as intermediates and additives. Today, Asia Pacific will focus on introducing what is called an intermediate and how it differs from APIs. Intermediates are also called organic intermediates. Use coal tar or petroleum products as raw materials to manufacture intermediate products such as dyes,Intermediate API pesticides, medicines,Intermediate API resins, additives,Intermediate API and plasticizers. Because it was originally used in the manufacture of dyes, it is also called dye intermediates,Intermediate API which are formed from cyclic compounds such as benzene,Intermediate API naphthalene, anthracene, etc. through sulfonation, alkali fusion, nitration, and reduction. For example,Intermediate API benzene is nitrated to nitrobenzene, and then reduced to aniline, which can be chemically processed into dyes, drugs,Intermediate API vulcanization accelerators, etc. Both nitrobenzene and aniline are intermediates.

There are acyclic compounds such as methane,Intermediate API acetylene, propylene, butane, butene, etc. through dehydrogenation, polymerization,Intermediate API halogenation, hydrolysis and other reactions. For example, butane or butene can be dehydrogenated into butadiene,Intermediate API and butadiene can be chemically processed into synthetic rubber and synthetic fibers. Butadiene is an intermediate. Initially,Intermediate API it refers to the intermediate products produced in the process of using coal tar or petroleum products as raw materials to synthesize chemical products such as spices, dyes, resins, drugs, plasticizers,Intermediate API and rubber accelerators. Now generally refers to various intermediate products obtained in the process of organic synthesis.

Intermediates refer to semi-finished products,Intermediate API which are intermediate products in the production of certain products. For example,Intermediate API to produce a product, it can be produced from intermediates to save costs. Pharmaceutical production requires a large number of special chemicals. Most of these chemicals were originally produced by the pharmaceutical industry. However,Intermediate API with the deepening of social division of labor and the advancement of production technology, the pharmaceutical industry has transferred some pharmaceutical intermediates to chemical companies for production. Pharmaceutical intermediates are fine chemical products,Intermediate API and the production of pharmaceutical intermediates has now become a major industry in the international chemical industry.
