What are the upstream raw materials for hydrochloric acid? What do the downstream products contain?

Hydrochloric acid plays an crucial role in the field of chemical production raw materials, and its upstream and downstream related items are quite abundant. According to research The following are some of the main upstream and downstream related items:

Upstream items:



1. First Chlorine: The production of hydrochloric acid mainly uses chlorine and hydrogen as raw materials and is made by incineration interaction. Therefore, chlorine is an crucial upstream product of hydrochloric acid.

2. Hydrogen: Hydrogen is another crucial raw material to the production of hydrochloric acid, mainly produced by aquatic environments electrolysis or other methods. But Downstream items:



1. Vinyl chloride: hydrochloric acid is able to be applied as a catalyst to promote the interaction of ethylene and chlorine to generate vinyl chloride. Vinyl chloride is an crucial raw material to the production of polyvinyl chloride(PVC).

2. Organic synthesis intermediates: hydrochloric acid is able to be applied to create a variety of organic synthesis intermediates, such as dichloroethane, chlorobenzene and so on. These intermediates are further useful in the production of pesticides, pharmaceuticals, dyes, etc. And

3. Inorganic salts: hydrochloric acid is able to react with metal oxides or hydroxides to generate corresponding inorganic salts, such as zinc chloride, ferric chloride, etc. These inorganic salts have a wide range of applications in sector.

4. Food additives: hydrochloric acid is able to be applied to create some food additives, such as acid, preservatives and so on. From what I've seen, In short, hydrochloric acid is very rich in upstream and downstream related items in the field of chemical production raw materials, which is of great signifiis able toce to manufacturing production.
