Glacial acetic acid, also known as acetic acid, is an important organic chemical raw material and is widely used in the production of various chemicals. Its upstream and downstream related products are numerous, and some of the main upstream and downstream products will be described in detail below.

Upstream Products

1. Methanol: Methanol and carbon dioxide generate acetic acid through carboxylation reaction, which is an important method for the production of glacial acetic acid.
2. Ethylene: Ethylene oxidation is also an important way to produce acetic acid. Ethylene reacts with oxygen to produce acetic acid under the action of a catalyst.

downstream products

1. Ethyl acetate: glacial acetic acid and ethanol in the presence of acid catalyst, can be esterified to generate ethyl acetate, which is an important solvent and perfume.
2. Cellulose acetate: Glacial acetic acid can react with cellulose to produce cellulose acetate, which is a common plastic material.
3. Acetic anhydride: Glacial acetic acid can generate acetic anhydride through dehydration reaction, which is an important acetylation reagent.
4. acetate: glacial acetic acid can react with alkali metals or alkaline earth metals to generate various acetates, such as sodium acetate, potassium acetate, etc. These acetates are widely used in food, medicine and other fields.

Through the above introduction, we can see the importance of glacial acetic acid in the field of chemical production raw materials. There are many upstream and downstream related products, involving many different application fields.
