About Acetic Anhydride
Acetic anhydride (ethanoic anhydride) has the formula C4H6O3 and is derived from Acetic (Ethanoic) Acid (CH3COOH). As an anhydride (literal meaning “without water”), it is made from a pair of acetic acid molecules via dehydration, i.e., that have had a H2O molecule eliminated. By reacting acetic anhydride with water, the process can be reversed to produce acetic acid.
At room temperature it is a clear, colorless liquid that has a distinct, sharp odor similar to that of a strong, white vinegar solution. This is due to the reaction with water vapor in the air that re-creates acetic acid (vinegar).
Acetic Anhydride is used extensively as a reagent in the synthesis of various organic molecules. In industry it is used in making plastics, drugs, dyes, perfumes, and explosives. In high schools and colleges it is often used in the synthesis of aspirin.
It is a highly corrosive substance with the potential to damage the skin and eyes.
