Read： 749 Time：12months ago Source：Transform the World with Simplicity

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 main upstream and downstream related products of 95% ethanol will be described in detail below.

Upstream Products

1. Corn: Corn is one of the main raw materials for the production of ethanol. The starch in corn is converted into glucose by enzymatic hydrolysis, and then the glucose is converted into ethanol by fermentation.
2. Cassava: Cassava is a starch-rich plant and an important raw material for ethanol production. Its production process is similar to that of corn.
3. Molasses: Molasses is a by-product of the sugar industry and is rich in fermentable sugars that can be used to produce ethanol.

Downstream Products

1. Acetaldehyde: Acetaldehyde is an important downstream product of ethanol, which can be prepared by the oxidation reaction of ethanol and is widely used in synthetic resins, rubber, dyes and other fields.
2. Acetic acid: Acetic acid can be produced by the oxidation reaction of ethanol, and is an important raw material for the production of ethyl acetate, cellulose acetate, etc.
3. Ether: Ether is a product of the reaction of ethanol with sulfuric acid and is widely used as a solvent and anesthetic.
4. Ethyl acetate: Ethyl acetate is the product of the esterification reaction of ethanol and acetic acid. It has a fruity flavor and is widely used as an additive in foods, beverages and spices.
5. Ethylene glycol: Ethylene glycol can be produced by the reduction reaction of ethanol and is widely used as an antifreeze, a solvent and a raw material for the synthesis of polyester fibers.

summary

95% ethanol has a wide range of applications in the field of chemical production raw materials, its upstream and downstream related products, including corn, cassava, molasses and other upstream raw materials, as well as acetaldehyde, acetic acid, ether, ethyl acetate, ethylene glycol and other downstream products. The production and application of these products involve many fields, such as medicine, food, beverage, spices, synthetic fibers, etc., which have an important impact on economic development and social life.
