Acetic acid, also known as acetic acid, is an important organic chemical raw material. It has a wide range of upstream and downstream related products, and many products play an important role in the field of chemical production raw materials. The following are some of the upstream and downstream associated products of acetic acid.

Upstream Products:

1. Methanol: Methanol and carbon dioxide generate acetic acid through carboxylation reaction, which is an important method for acetic acid production.
2. Ethanol: Ethanol oxidation is also an important process for the production of acetic acid. Ethanol is oxidized to acetic acid in the presence of a catalyst.

Downstream Products:

1. Ethyl acetate: Acetic acid and ethanol are esterified in the presence of an acid catalyst to produce ethyl acetate, which is an important solvent and fragrance.
2. Cellulose acetate: Acetic acid reacts with cellulose to produce cellulose acetate, an important plastic material.
3. Acetic Anhydride: Two molecules of acetic acid are dehydrated in the presence of a catalyst to produce acetic anhydride, which is an important acylating agent.
4. Acetate: Acetic acid reacts with various bases to form acetate, such as sodium acetate, potassium acetate, etc. These compounds are used in many fields.

above only listed a part of the upstream and downstream associated products of acetic acid, in fact, acetic acid is very widely used, and there are many upstream and downstream associated products.
