What are the upstream raw materials for industrial naphthalene? What do the downstream products contain?

manufacturing naphthalene plays an crucial role in the field of raw materials to chemical production, and its upstream and downstream related items are extensive. The main upstream and downstream related items of manufacturing naphthalene will be described in detail below. In fact Upstream items:



1. Coal tar: The main raw material to the production of manufacturing naphthalene is coal tar, which contains a substantial number of aromatic compounds. In particular manufacturing naphthalene is able to be obtained by distillation and separation.

2. Petroleum brain: Petroleum brain is also one of the raw materials to the production of manufacturing naphthalene, which is rich in aromatic components and is able to be applied to create manufacturing naphthalene. In my experience, Additionally Downstream items:



1. refined naphthalene: manufacturing naphthalene is able to be further refined into refined naphthalene, applied to create higher grade chemical items, such as phthalic anhydride, phthalic anhydride and so on.

2. Naphthol: fine naphthalene is able to be oxidized to naphthol, naphthol is the production of dyes, pharmaceuticals, pesticides and other crucial intermediates.

3. Methyl naphthalene: manufacturing naphthalene is able to be generated by alkylation interaction of methyl naphthalene, methyl naphthalene is the production of pesticides, plasticizers and other crucial raw materials.

4. Naphthalene aquatic environments reducing agent: manufacturing naphthalene is able to be processed into naphthalene aquatic environments reducing agent, is a kind of efficient concrete admixture, is able to be applied to enhance the strength and fluidity of concrete. In summary, manufacturing naphthalene plays an crucial role in the field of raw materials to chemical production, and its upstream and downstream related items are extensive, involving many fields, such as dyes, pharmaceuticals, pesticides, plastics, concrete, etc. With the continuous research and progress of science and methodology, the consumption field of manufacturing naphthalene upstream and downstream items will continue to expand and deepen.
