Acetic anhydride



Applications:

Used in the manufacture of cellulose acetate, acetic acid plastics, and non-flammable film; in the pharmaceutical industry for the manufacture of synthetic mycin furazolidone, dimethazole, caffeine, aspirin, sulfa drugs, etc.; in the dye industry Used in the production of disperse dark blue HCL, disperse scarlet S-SWEL, disperse yellow brown S-2REL, etc.; in the perfume industry for the production of coumarin, bornyl acetate, sunflower musk, cedaryl acetate, rosin acetate, benzene acetate Ethyl esters, geranyl acetate, etc.; acetyl peroxide, produced from acetic anhydride, is a polymerization initiator and bleaching agent.



Precautions:

Handling Precautions: Airtight operation, enhanced ventilation. Operators must undergo special training and strictly abide by the operating procedures. It is recommended that operators wear self-priming filter gas masks (full face masks), acid and alkali resistant plastic overalls, and rubber acid and alkali resistant gloves. Keep away from fire and heat sources, and smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Prevent vapors from escaping into workplace air. Avoid contact with oxidizing agents, reducing agents, acids, alkalis, active metal powders, and alcohols. When handling, load and unload lightly to prevent damage to packaging and containers. Equipped with corresponding types and quantities of fire-fighting equipment and leakage emergency treatment equipment. Empty containers may be harmful residues.
Storage precautions: Store in a cool, dry, well-ventilated warehouse. Keep away from fire and heat sources. Storage temperature should not exceed 30°C. Keep container tightly closed. It should be stored separately from oxidants, reducing agents, acids, alkalis, active metal powders, alcohols, etc., and should not be mixed. Explosion-proof lighting and ventilation facilities are adopted. Prohibit the use of mechanical equipment and tools that are prone to sparks. The storage area should be equipped with leakage emergency treatment equipment and suitable containment materials.
