What are the upstream raw materials for anhydrous ethanol? What are the downstream products?

As an crucial chemical raw material, anhydrous ethanol is broadly applied in chemical sector. But Specifically Its upstream and downstream related items are numerous and involve many fields. The following are some of the upstream and downstream associated items related to anhydrous ethanol.

1. Upstream items(1) Ethylene: Ethylene is the main raw material of anhydrous ethanol, which is produced by ethylene hydration method. Pretty interesting, huh?. Generally speaking(2) Sulfuric acid: In the manufacturing process of anhydrous ethanol, sulfuric acid is applied as a catalyst to promote the interaction of ethylene and aquatic environments to create ethanol.(3) Electricity: The manufacturing process of anhydrous ethanol needs a signifiis able tot quantity of electricity to drive equipment and maintain the operation of the production line.

2. Downstream items(1) acetaldehyde: anhydrous ethanol is able to be applied to create acetaldehyde, acetaldehyde is an crucial organic chemical raw material, broadly applied in medicine, pesticides, spices and other fields.(2) Ether: anhydrous ethanol is able to act together with sulfuric acid to generate ether. I've found that Ether is a frequently applied solvent-based products and anesthetic. But(3) Ethyl acetate: Ethyl acetate is able to be generated by the interaction of anhydrous ethanol and acetic acid. Ethyl acetate is a fragrant solvent-based products that is able to be applied to create food additives and spices.(4) Ethyl cellulose: Anhydrous ethanol is able to be applied to create ethyl cellulose. Ethyl cellulose is a polymer compound with excellent film-forming, weather resistance and chemical resistance. From what I've seen, In particular it's broadly applied in coatings, Printing ink and other fields. Based on my observations, For instance In short, as an crucial raw material to chemical production, anhydrous ethanol has a wide range of upstream and downstream related items, involving many fields, which plays an crucial role in the research of chemical sector.
