설명

일반 설명

Acetic anhydride (CH₃CO)₂O, also known as ethanoric anhydride, is a colorless liquid with a strong pungent odor. It has a boiling point of 140°C (284°F). It is soluble in cold water, decomposes in hot water to form acetic acid, and is soluble in alcohol, chloroform and ether. It is a highly corrosive flammable liquid with harmful vapour. Exposure to acetic anhydride can occur via eye or skin contact, ingestion and inhalation.
