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

1. Upstream products

(1) Corn: Corn is one of the main raw materials for ethanol production, and it can be converted into ethanol through enzymatic fermentation process.

(2) Cassava: Cassava is a starch-rich plant that can also be used to produce ethanol.

(3) Waste molasses: Waste molasses is a by-product of the sugar industry and can also be used to produce ethanol.

2. Downstream product

(1) Acetaldehyde: Ethanol can generate acetaldehyde through oxidation reaction. Acetaldehyde is an important organic chemical raw material and can be used to produce many chemicals, such as acetic acid, acetic anhydride, ethyl acetate Wait.

(2) Ethyl acetate: Ethanol can react with acetic acid to produce ethyl acetate, which is a common solvent and fragrance.

(3) Ethyl tert-butyl ether: Ethanol can react with isobutylene to form ethyl tert-butyl ether, which is an excellent gasoline additive and can increase the octane number of gasoline.

(4) Ether: Ethanol can be dehydrated under acidic conditions to form ether, which is a commonly used solvent and anesthetic.

In short, 95 ethanol has a wide range of applications in the field of chemical production raw materials, and its upstream and downstream related products are numerous. The production and use of these products involve many fields, such as medicine, pesticides, food, energy, etc.
