Physical and Chemical Properties
Acetic anhydride, or ethanoic anhydride, is the chemical compound with the formula (CH3CO)2O. Commonly abbreviated Ac2O, it is the simplest isolable anhydride of a carboxylic acid and is widely used as a reagent in organic synthesis. It is a colorless liquid that smells strongly of acetic acid, which is formed by its reaction with moisture in the air.

Application
1.acetic anhydride is mainly used for acetylations leading
2.acetic anhydride is for the conversion of cellulose to cellulose acetate, which is a component of photographic film and other coated materials, and is used in the manufacture of cigarette filters.
3. it is used in the production of aspirin (acetylsalicylic acid), which is prepared by the acetylation of salicylic acid.
4.It is also used as an active modification agent via autoclave impregnation and subsequent acetylation to make a durable and long-lasting timber.
5.acetic anhydride is used for the production of modified starches
6.it is used in the non-combustible film film, also used as strong acetic acid acyl agent, dehydrating agent for sulfonation and nitration, etc.
Storage
Acetic anhydride is an irritant and combustible liquid; it is highly corrosive to skin and any direct contact will result in severe burns. Because of its reactivity toward water and alcohol, foam or carbon dioxide are preferred for fire suppression.The vapour of acetic anhydride is harmful.
