• As examples, a water molecule easily adds to ketene to give 1,1-dihydroxyethene and acetic anhydride is produced by the reaction of acetic acid with ketene.
• The morphine base is then reacted with acetic anhydride, which forms heroin.
• Synthesis by oxidation of acetic anhydride by peroxides, is conceptually similar.
• Salicylic acid is treated with acetic anhydride, an acid derivative, causing a chemical reaction that turns salicylic acid's hydroxyl group into an ester group (R-OH → R-OCOCH3).
• This was based on reacting paraformaldehyde and ammonium nitrate in acetic anhydride.

• Urea and acetaldehyde combine to give a useful resin. Acetic anhydride reacts with acetaldehyde to give ethylidene diacetate, a precursor to vinyl acetate, which is used to produce polyvinyl acetate.
• D-glucose is first protected by forming the peracetate by addition of acetic anhydride in acetic acid, and then addition of hydrogen bromide which brominates at the 5-position.
• The classical methods for the production of paracetamol involve the acetylation of 4-aminophenol with acetic anhydride as the last step.
• Samples are chemically processed with a mix of acids, sodium hydroxide, acetic anhydride with water washes in between.
• It may be produced by nitration of hexamine in the presence of acetic anhydride, paraformaldehyde and ammonium nitrate.

• It is a plant hormone, Aspirin (acetylsalicylic acid or ASA) is prepared by the esterification of the phenolic hydroxyl group of salicylic acid with the acetyl group from acetic anhydride or acetyl chloride.
• In 1865, French chemist Paul Schützenberger discovered that cellulose reacts with acetic anhydride to form cellulose acetate.
• Morphine is converted into heroin by a simple chemical reaction with acetic anhydride, followed by purification.
• - Morphine is commonly treated with acetic anhydride and ignited to yield heroin.
• Between the 1960s and 1980s methanol emerged as a precursor to the feedstock chemicals acetic acid and acetic anhydride.

• Many chemical reaction systems for the modification of wood, especially those using various types of anhydrides, have been published; however, the reaction of wood with acetic anhydride has been the most studied.
• With cyanuric chloride or trifluoroacetic anhydride instead of oxalyl chloride, the reaction can be warmed to −30 °C without side reactions.
