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 ...
