Acetic propionic anhydride. 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 synthesisIt is a colorless liquid that smells strongly of acetic acid which is formed by its reaction with moisture in the air. The product of the condensation of two molecules of acetic acid is acetic anhydride.
The worldwide production of acetic anhydride is a major application and uses approximately 25 to 30 of the global production of acetic acid. The main process involves dehydration of acetic acid to give ketene at 700750 C.
