Acetic anhydride meaning

Acetic anhydride definitions

Acetic anhydride, also known as ethanoic anhydride, is a colorless liquid with a pungent odor. This chemical compound is commonly used in the production of various organic compounds, including aspirin, modified starches, and cellulose acetate. Its chemical formula is (CH₃CO)₂O, indicating that it is composed of two acetyl groups attached to an oxygen atom.

Uses of Acetic Anhydride

One of the primary uses of acetic anhydride is in the production of cellulose acetate, a type of plastic that is used in the production of photographic film. It is also used in the synthesis of various pharmaceuticals, such as aspirin and paracetamol. Additionally, acetic anhydride is utilized in the production of pesticides, fragrances, and dyes.

Chemical Properties

Acetic anhydride is a versatile reagent in organic synthesis due to its ability to acetylate substances. It can react with a variety of compounds containing hydroxyl or amino groups to form acetate esters. This reaction is often used in the synthesis of various pharmaceuticals and organic chemicals.

Handling and Safety

Acetic anhydride is a hazardous chemical that can cause severe burns upon contact with skin and eyes. It is also a respiratory irritant and can cause lung damage if inhaled. Proper safety precautions, including the use of personal protective equipment such as gloves and goggles, are essential when handling this compound.
