Acetic anhydride is an organic substance with the chemical formula C4H6O3. It is a colorless and transparent liquid with a strong acetic acid odor, sour taste, and hygroscopicity. It is soluble in chloroform and ether, slowly soluble in water to form acetic acid, and reacts with ethanol to form ethyl acetate. Flammable, corrosive and easy to tear.

Acetic anhydride is an important acetylation agent. acetic anhydride is used in the manufacture of cellulose acetate, acetate plastics, and non-combustible films; In the pharmaceutical industry, it is used in the manufacture of synthromycin, dysentery, diazole, caffeine, aspirin, sulfonamides, etc.; In the dye industry, it is mainly used for the production of dispersed dark blue HCl, dispersed scarlet swel, dispersed yellow-brown s-2rel, etc.; In the spice industry, it is used to produce coumarin, bornyl acetate, sunflower seed musk, cedar acetate, phenylethyl acetate, geranyl acetate, etc.; Acetyl peroxide produced by acetic anhydride is an initiator and bleaching agent for polymerization reactions. It is used for the detection of alcohols, aromatic primary amines and secondary amines; It is used in organic synthesis, dyes, pharmaceutical industry and the manufacture of acetyl compounds. As a solvent and dehydrating agent, it is also an important acetylation reagent and polymer initiator. The final product is cellulose acetate and cellulose acetate plastics. It is also used in the manufacture of heroin, 1-phenyl-2-acetone, and N-acetylanthranitic acid. It is also a preparation for the production of methamphetamine, methamphetamine, and methamphetamine. It is also a raw material for acetate starch.
