Uses of Chemical Intermediates

 As one of the best pharmaceutical intermediates and active pharma ingredients manufacturers from China, Aolisenchem has continuously improved the core competitiveness of chemical intermediates production technology, which is specifically reflected in the choice of chemical reaction process, process control, the choice of core catalysts and so on, strive to improve the production efficiency and product quality of the enterprise, continue to innovate independently, and expand various unit reaction processes.

 

Uses of Chemical Intermediates

1. The development of chemical intermediates

The research and production of chemical intermediates tend to be appropriately centralized to realize series production.A set of production equipment can product several to a dozen kinds of intermediates. Through overall development, such research and production is relatively easy to implement with new technology, and will yield twice the result with half the effort.

 

2. Uses of chemical intermediates

The uses and development of chemical intermediate are multifaceted. A certain kind of intermediate used in dyes is called dye intermediates,while it is also called pesticide intermediate and pharmaceutical intermediate when used in pesticides and medicine. Intermediates should be considered as a whole branch of fine chemical intermediates industry.

 

The research of fine chemical intermediates is characterized by a wide varieties.Except that a few varieties have a particularly large production scale,the tonnage of most varieties is not very large. However, its preparation process is often complex, many unit reactions and separation processes, and a considerable amount of "three wastes" are generated in production, which need to be properly treated. Therefore, we should study the process of serial products, and reasonably organize the production of intermediates in order to obtain good economies of scale.

 

The raw materials required for chemical intermediates are mainly obtained from the products of petroleum and coking chemical industry. Most of them are benzene compounds, naphthalene  compounds and anthraquinone compounds, as well as some heterocyclic compounds. In recent years, the organic pigments prepared from heterocyclic compounds are on the rise.

 

In addition, phenanthrene, pyridine, dibenzofuran, quinoline, indole, carbazole, and biphenyl series compounds, these complex raw materials are applied to the manufacture of dyes, which  makes the use of chemical intermediates more extensive and universal.
