PPD (hydroquinone) is a common chemical raw material, which is widely used in various fields. In the field of raw materials for chemical production, the upstream and downstream related products of PPD mainly include the following categories:

1. Upstream product

(1) Benzene: Benzene is one of the main raw materials of PPD, and PPD can be produced through oxidation, dehydrogenation and other reactions.

(2) Hydrogen: Hydrogen is also an important raw material in the production of PPD for the reduction reaction.

(3) Catalyst: The production process of PPD requires the use of catalysts, such as copper, zinc and other metal salts, to promote the reaction.

2. Downstream product

(1) Pesticides: PPD can be used as an intermediate of pesticides for the production of fungicides, herbicides, etc.

(2) Dyes: PPD can be used to produce various dyes, such as acid dyes, direct dyes, etc.

(3) Pharmaceutical intermediates: PPD can also be used as pharmaceutical intermediates for the production of antioxidants, anti-inflammatory drugs.

(4) Antioxidant: PPD itself is also a commonly used antioxidant, which can be used to prevent oxidative aging of polymer materials, fats and oils.

In short, PPD, as an important chemical raw material, has a wide range of upstream and downstream related products, involving pesticides, dyes, pharmaceuticals, antioxidants and other fields.
