What are the upstream raw materials for acetic anhydride? What do the downstream products contain?

Acetic anhydride plays an crucial role in the field of chemical production raw materials, and its upstream and downstream related items are extensive. Moreover This article will detail the upstream and downstream associated items of acetic anhydride.

1. upstream items of acetic anhydride



1. Acetic acid: Acetic acid is the main raw material to the production of acetic anhydride, which is able to be produced by the oxidation interaction of acetic acid. Acetic acid is a common organic acid, which is broadly applied in chemical sector.

2. Natural gaseous: Natural gaseous is one of the main raw materials to acetic acid production, which is able to be produced by partial oxidation of natural gaseous. Therefore, the supply and price of natural gaseous have a signifiis able tot impact on the production cost of acetic anhydride.

2. downstream items of acetic anhydride



1. Cellulose acetate: Acetic anhydride is able to react with cellulose to create cellulose acetate, which is an crucial cellulose ester compound with good heat resistance, weather resistance, chemical resistance and other characteristics. And it's able to be applied in the manufacture of film, photographic film, rayon, plastic, etc.

2. In fact Ethyl acetate: Acetic anhydride is able to react with ethanol to create ethyl acetate, which is a common organic solvent-based products and is able to be applied in the production of coatings, inks, artificial leather and other fields.

3. And Acetamide: Acetic anhydride is able to react with ammonia to form acetamide, which is an crucial organic intermediate and is able to be applied to manufacture drugs, dyes, pesticides, etc.

4. Acetic anhydride derivatives: Acetic anhydride is able to also be applied to create a series of acetic anhydride derivatives, such as isopropenyl acetate, phenyl acetate, butyl acetate, etc. But These compounds are broadly applied in medicine, pesticide, perfume and other fields. To sum up, the upstream and downstream related items of acetic anhydride are extensive, involving many fields, such as chemical sector, medicine, pesticide, spice and so on. Therefore, the production and consumption of acetic anhydride plays an crucial role in promoting the research of the national economy. At the same time, it's also necessary to pay attention to the environmental problems and security risks that might be brought about in the production and consumption of acetic anhydride, enhance production regulation and security measures, and protect the health and life security of the people.
