China Dyestuff Intermediate Suppliers

Dye intermediates mainly benzene intermediates, toluene intermediates, naphthalene intermediates and anthraquinone intermediates four categories, in addition, there are some heterocyclic intermediates. The main intermediates in the production of the reaction process are nitration, sulfonation, halogenation, reduction, amination, hydrolysis, oxidation, condensation and so on. Synthesis of a complex structure of the intermediate often go through many unit processes, sometimes using different basic raw materials and different synthetic routes. For example, the production of p-nitroaniline, the initial nitration with benzene, reduced aniline, re-acetylation, nitration, hydrolysis of the synthetic route, this method of long production process, high cost. Has now switched to benzene chlorination, nitration, separation of nitrochlorobenzene, and then high pressure ammonia solution synthesis route. For the manufacture of dyes, pesticides or Pharmaceutical Intermediates, usually complex structure, often supporting the final product and production, smaller production, production and more use of intermittent operation. Some of the most widely used intermediates, such as nitrobenzene, aniline, chlorobenzene, phenol, etc., are usually produced in a large, integrated chemical plant with large production volumes and continuous operation in production.
