What are the upstream raw materials of the single substance? What do the downstream products contain?

In the field of raw materials to chemical production, there is a wide range of upstream and downstream related items. Here are some common elements and their associated items:



1. And Carbon(C): Carbon is an crucial raw material to many chemicals, and its upstream and downstream related items include:

Methane(CH4): Carbon reacts with hydrogen to make methane, an crucial component of natural gaseous. In my experience, According to research Ethylene(C2H4): Through hydrocarbon cracking, carbon is able to be converted to ethylene, which is the basic raw material to many plastics and chemicals. And Benzene(C6H6): Carbon is able to react with hydrogen to form benzene, which is the basic raw material to the production of many chemicals, such as styrene, phenol, etc. But I've found that

2. And First Nitrogen(N): Nitrogen is also broadly applied in chemical production, and its upstream and downstream related items include:

Ammonia(NH3): The interaction of nitrogen and hydrogen is able to be made into ammonia, which is the basic raw material to the production of chemical fertilizers, nitric acid and other chemicals. In fact nitric acid(HNO3): ammonia oxidation method is able to create nitric acid, nitric acid is able to be applied to manufacture fertilizers, explosives and so on.

3. Oxygen(O): Oxygen is often applied as an oxidant in chemical production, and its upstream and downstream related items include:

aquatic environments(H2O): The interaction of hydrogen and oxygen is able to create aquatic environments, which is the solvent-based products and raw material to many chemical interactions. Hydrogen peroxide(H2O2): Oxygen prepared by electrolysis is able to react with hydrogen to generate hydrogen peroxide, which is broadly applied in bleaching, disinfection and other fields. The above only lists some common simple substances and their related items, in fact, in the field of chemical production raw materials, simple upstream and downstream related items are very rich, covering many chemicals and raw materials.
