Chemical of the Week -- Acetic Acid and Acetic Anhydride

Acetic anhydride is a clear, colorless, mobile (free-flowing) liquid with a sharp odor similar to that of acetic acid. It hydrolyzes in water to yield acetic acid. In its liquid or vapor state, acetic anhydride can irritate body tissues, possibly leading to the death of such tissue. Acetic anhydride melts at –73C, boils at 139C, and has a ...

Acetic anhydride is produced from glacial acetic acid via ketene (CAS no 463-51-4 ). Acetic acid is vaporized and fed together with a catalyst to a cracking furnace operating under vacuum where ketene is produced together with water at high temperature. The reaction mixture is rapidly cooled to avoid the reversing of the reaction.
