Acetic anhydride is the chemical compound with the formula (CH 3 CO) 2 O. Commonly abbreviated Ac 2 O, it is one of the simplest acid anhydrides and is a widely used reagent in organic synthesis. It is a colorless liquid that smells strongly of acetic acid , which is formed by its reaction with the moisture in the air.
Boiling Point: 138-140 C. Density: 1.08 g/mL at 20 C. Acetic anhydride (Ac2O) is a liquid with a strong acetic acid smell (acetic acid is liberated during the hydrolysis of acetic anhydride by moisture in the air). Acetic anhydride is typically used for acetylation of alcohols or amines.
