Application:
as indicated by its organic chemistry, Ac2O is mainly used for acetylations leading to commercially significant materials.  Its largest application is for the conversion of cellulose to cellulose acetate, which is a component of photographic film and other coated materials. Similarly it is used in the production of aspirin, which is prepared by the acetylation of salicylic acid. It is also used as a wood preservative via autoclave impregnation to make a longer lasting timber.
In starch industry, acetic anhydride is a common acetylation compound, used for the production of modifier starches.
