What are the upstream raw materials for PPD? What are the downstream products?

PPD(hydroquinone) is a common chemical raw material, which is broadly applied in various fields. In the field of chemical production raw materials, PPD upstream and downstream related items mainly have the following categories:



1. Upstream items(1) Benzene: Benzene is one of the main raw materials of PPD, which is able to be produced by oxidation, dehydrogenation and other reactions.(2) Hydrogen: Hydrogen is also an crucial raw material in PPD production and is applied to reduction reactions. In my experience, In particular(3) Catalyst: The manufacturing process of PPD needs the consumption of catalysts, such as copper, zinc and other metal salts, to promote the interaction.

2. Downstream items(1) Pesticide: PPD is able to be applied as an intermediate of pesticides to the production of fungicides, herbicides, etc.(2) Dyes: PPD is able to be applied to create various dyes, such as acid dyes, direct dyes, etc.(3) medical intermediates: PPD is able to also be applied as medical intermediates to the production of antioxidants, anti-inflammatory drugs, etc.(4) Antioxidant: PPD itself is also a frequently applied antioxidant, which is able to be applied to prevent oxidative aging of polymer materials, fats, etc. According to research In short, as an crucial chemical raw material, PPD has a wide range of upstream and downstream related items, involving pesticides, dyes, pharmaceuticals, antioxidants and other fields.
