It is flammable, and its vapor and air can form an explosive mixture, which can cause combustion and explosion when exposed to open flames or high heat.

Chemical reactions may occur on contact with strong oxidizing agents. It can form acetate and acetamide compounds with alcohol, phenol and amine respectively.

In the presence of Lewis acid, acetic anhydride can also acetylate aromatic hydrocarbons or alkenes. In the presence of sodium acetate, acetic anhydride and benzaldehyde undergo a condensation reaction to form cinnamic acid.

Slowly dissolves in water and becomes acetic acid. It reacts with alcohols to form acetate.

Acetic anhydride is an important acetylation reagent. Acetic anhydride is used in the manufacture of cellulose acetate, acetate plastics, and non-flammable film films; in the pharmaceutical industry, it is used in the manufacture of the synthetic mycin furazole, dibazole, caffeine, and aspirin. , sulfonamide drugs, etc.;

In the dye industry, it is mainly used to produce dispersed dark blue HCL, dispersed red S-SWEL, dispersed yellow brown S-2REL, etc.; in the spice industry, it is used to produce coumarin, bornyl acetate, sunflower musk, cypress acetate, Phenethyl acetate, geranyl acetate, etc.;

Acetyl peroxide, produced from acetic anhydride, is an initiator and bleaching agent for polymerization reactions. Used for testing alcohols, aromatic primary amines and secondary amines; used in organic synthesis, dyes, pharmaceutical industry and manufacturing acetyl compounds.

Used as a solvent and dehydrating agent, it is also an important acetylation reagent and polymer initiator. Application The final products are cellulose acetate and cellulose acetate plastic.

It can also be used to make heroin, 1-phenyl-2-propanone and N-acetyl anthranilic acid, and is also a preparation for the production of methaphone, methaphone, and methamphetamine.
