What is a pesticide intermediate? What are the common types?
The intermediates are divided into various types, including pharmaceutical intermediates, pesticide intermediates, and so on. Today, Xiao Bian gave you a briefing on what pesticide intermediates are, and what are the common types? Please follow up with the pace of this Xiao Bian!
The product produced by the processing of agricultural raw materials is an intermediate medium that combines two or more substances. In pesticides can be understood as a synergist, is the intermediate material for the production of pesticides.
Also known as organic intermediates. Coal tar or petroleum products are used as raw materials to produce intermediates such as dyes, pesticides, medicines, resins, auxiliaries, and plasticizers. Because it was originally used to make dyes, it is also called dye intermediates.
There are cyclic compounds such as benzene, naphthalene, anthraquinone and other sulfonation, alkali melting, nitration, reduction and other reactions.
For example, benzene is nitrated to nitrobenzene and then reduced to aniline. Aniline can be chemically processed into dyes, drugs, vulcanization accelerators, and the like. Both nitrobenzene and aniline are intermediates.
There are acyclic compounds such as methane, acetylene, propylene, butane, butene, etc. which are dehydrogenated, polymerized, halogenated, and hydrolyzed.
For example, butane or butene can be dehydrogenated to butadiene, and butadiene can be chemically processed into synthetic rubber, synthetic fibers, and the like. Butadiene is an intermediate.
Initially, it refers to the intermediate products produced during the process of synthesizing chemical products such as perfumes, dyes, resins, drugs, plasticizers, and rubber accelerators using coal tar or petroleum products as raw materials. Now refers to the various intermediate products obtained during organic synthesis.
Intermediates refer to semi-finished products, which are intermediate products for the production of certain products, such as the production of a product that can be produced from intermediates and save costs. Pharmaceutical production requires a large amount of special chemicals. Most of these chemicals were originally produced by the pharmaceutical industry. However, with the deepening of social division of labor and advances in production technology, the pharmaceutical industry has transferred some pharmaceutical intermediates to chemical companies for production. The pharmaceutical intermediates are fine chemical products, and the production of pharmaceutical intermediates has now become a major industry in the international chemical industry.
