General description

Acetic anhydride is a colorless liquid. On dissolution in water, it undergoes solvolysis to afford acetic acid. It is widely employed as acetylation reagent for the acetylation of various alcohols. Wacher process (starting reagent + a ketene) and Knapsack process (starting reagent = acetaldehyde) have been reported for the industrial preparation of acetic anhydride. It is employed as solvent for various organic reactions.
