Description
A chemical reaction that adds an acetyl radical (CH3CO-) to a molecule in place of an -OH or -NH2 group. For example, acetylation will convert ethanol to ethyl acetate or cellulose to cellulose acetate. Acetic anhydride is used as an acetylation agent. The number of hydroxyl groups in fats and oils can be determined using acetylation and is reported as the acetyl value.
