essential information

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

application area 

Acetic anhydride is an important acetylation reagent used in the production of cellulose acetate, acetate plastics, and non combustible film; In the pharmaceutical industry, it is used to manufacture synthetic drugs such as streptozotocin, tebuconazole, caffeine and aspirin, sulfonamide drugs, etc; In the dye industry, it is mainly used to produce dispersed deep blue HCL, dispersed bright red S-SWEL, dispersed yellow brown S-2REL, etc; Used in the spice industry for the production of coumarin, bornyl acetate, musk, cedarwood acetate, phenethyl acetate, geranyl acetate, etc; Acetyl peroxide, produced from acetic anhydride, is an initiator and bleaching agent in polymerization reactions. Used for testing alcohols, aromatic primary and secondary amines; Used in organic synthesis, dyes, pharmaceutical industry, and manufacturing of acetyl compounds. Used as a solvent and dehydrating agent, it is also an important acetylation reagent and polymer initiator. The end products of the application are cellulose acetate and cellulose acetate plastic. It can also be used to manufacture heroin, 1-phenyl-2-propanone, and N-acetylanthranilic acid, and is also a formulation for the production of methaqualone, neomethaqualone, and methamphetamine.

Packaging, Storage, Transportation, and Safety

Precautions for operation: Closed operation, strengthen ventilation. Operators must undergo specialized training and strictly adhere to operating procedures. It is recommended that operators wear self-priming filter type gas masks (full face shields), acid and alkali resistant plastic work clothes, and rubber acid and alkali resistant gloves. Keep away from sources of fire and heat, and smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Prevent steam leakage into the workplace air. Avoid contact with oxidants, reducing agents, acids, bases, active metal powders, and alcohols. Handle with care during transportation to prevent damage to packaging and containers. Equip with corresponding types and quantities of fire-fighting equipment and emergency response equipment for leaks. Empty containers may contain residual harmful substances.
Storage precautions: Store in a cool, dry, and well ventilated warehouse. Stay away from sources of fire and heat. The storage temperature should not exceed 30 ℃. Keep the container sealed. It should be stored separately from oxidants, reducing agents, acids, bases, active metal powders, alcohols, etc., and mixed storage should be avoided. Adopt explosion-proof lighting and ventilation facilities. Prohibit the use of mechanical equipment and tools that are prone to generating sparks. The storage area should be equipped with emergency response equipment for leaks and suitable containment materials.
