Acetic anhydride can be obtained directly by liquid-phase oxidation of acetaldehyde. The peracetic acid formed from oxygen and acetaldehyde reacts under suitable conditions with a second molecule of acetaldehyde to form acetic anhydride and water .
Acetic anhydride, or ethanoic anhydride, is the chemical compound with the formula (CH 3 CO) 2 O. Commonly abbreviated Ac 2 O , it is the simplest isolable anhydride of a carboxylic acid and is widely used as a reagent in organic synthesis .

12 Φεβ 2024 · Acetic anhydride is a colorless organic liquid with the formula (CH3CO)2O and the simplest example of a carboxylic acid anhydride (the simpler formic anhydride is too unstable to exist as pure substance). It is a very useful reagent in organic synthesis. Contents. 1 Properties. 1.1 Chemical. 1.2 Physical. 2 Availability. 2.1 Restrictions.
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.
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.
