Company information
The company's main import and export products include:
（1）Organic Raw Materials：It has a wide range of uses, which can be divided into three aspects: first, it is used as a raw material for the production of polymer chemical products, i.e., monomers for polymerisation reactions; second, it is used as a raw material for other organic chemical industries, including fine chemical products; and third, it is used as a solvent, refrigerant, antifreeze, and gas adsorbent. Basic organic chemical industry is the basis for the development of the production of various organic chemical products, is the main component of the modern industrial structure.
（2）Intermediates：Intermediates are semi-finished products, which are products in the middle of the production of certain products, for example, to produce a product, which can be produced from intermediates to save costs.Intermediates are available from cyclic compounds such as benzene, naphthalene, anthracene, etc. by sulfonation, alkali fusion, nitration, reduction and other reactions.Our Intermediates products include pharmaceutical intermediates, pesticide intermediates and dye intermediates.
