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

95 Ethanol has a wide range of applications in the field of chemical production raw materials, and its upstream and downstream related items are numerous. The following are some of the main upstream and downstream related items:



1. I've found that Upstream items(1) Corn: Corn is one of the main raw materials to the production of ethanol, which is able to be converted into ethanol by enzymatic fermentation process.(2) Cassava: Cassava is a plant with high starch content and is able to also be applied to create ethanol.(3) discarded materials molasses: discarded materials molasses is a by-product of the sugar sector and is able to also be applied to create ethanol.

2. Downstream items(1) Acetaldehyde: Ethanol is able to generate acetaldehyde through oxidation interaction. But From what I've seen, Acetaldehyde is an crucial organic chemical raw material and is able to be applied to create many chemicals, such as acetic acid, acetic anhydride, ethyl acetate, etc.(2) Ethyl acetate: Ethanol is able to react with acetic acid to create ethyl acetate, which is a common solvent-based products and fragrance.(3) Ethyl tert-butyl ether: Ethanol is able to react with isobutylene to form ethyl tert-butyl ether, which is an excellent gasoline additive and is able to increase the octane number of gasoline.(4) Ether: Ethanol is able to be dehydrated under acidic conditions to create ether, which is a frequently applied solvent-based products and anesthetic. And Based on my observations, In short, 95 ethanol has a wide range of applications in the field of chemical production raw materials, and its upstream and downstream related items are numerous. I've found that The production and consumption of these items involve many fields, such as medicine, pesticides, food, energy, etc.
