Quality specification(GB/T 1628-2008)

Physicochemical properties:
1. Colorless liquid and irritating dour.
2. Melting point 16.6 ℃; boiling point 117.9℃; Flash point : 39 ℃.
3. Solubility  water, ethanol, benzene and ethyl ether immiscible, insoluble in carbon disulphide.

Storage:
1. Stored in a cool, ventilated warehouse.
2. Keep away from the fire, heat. The cold season should maintain a temperature higher than 16 DEG C, to prevent solidification. During cold season, temperature should be maintained above 16 DEG C to prevent/avoid solidification.
3. Keep the container sealed. Should be separated from the oxidant and alkali. Mixing should be avoided by all means.
4. Use explosion-proof lighting, ventilation facilities.
5. Mechanical equipment and tools that prohibit the use of easy to produce sparks.
6. Storage areas should be equipped with emergency treatment equipment and suitable housing materials.

Use:

1.Derivative:Mainly used in synthetising acetic anhydride,acetic ether,PTA, VAC/PVA,CA,ethenone,chloroacetic acid,etc
2.Pharmaceutical:Acetic acid as solvent and pharmaceuticalraw materials, mainly used for production of penicilin G potas-sium, penicilin G sodium, penicillin procaine, acetanilide,sulfadiazine, and sulfamethoxazole isoxazole, norfloxacin,ciprofloxacin, acetyl salicylic acid, non phenacetin, prednisone,caffeine, etc.
3.Intermediate:acetate ,sodium hydrogen di,peracetic acid,etc
4.Dyestuff and textile printing and dyeing:Mainly used inproducing disperse dyes and vat dyes,and textile printing anddyeing processing
5. Synthesis ammonia: In the form of cuprammonia acetate,used in refining syngas to remove a litl CO and CO2
6. Photograph: Developer
7. Natural rubber: Coagulant
8. Construction industry: Preventing concrete from frezing9. In addtin also widely used in the water treatment, syntheticfiber, pesticides, plastics, leather, paint, metal processing andrubber industry

Glacial acetic acid (pure matter), that is, anhydrous acetic acid, acetic acid is one of the important organic acids, organic compounds. It solidifies into ice at low temperature, commonly known as glacial acetic acid. Volume expansion during solidification may cause the container to break. Flash point 39℃, explosion limit 4.0%~16.0%, the maximum allowable concentration in the air is not more than 25mg/m3. Pure acetic acid will freeze into ice crystals below the melting point, so anhydrous acetic acid is also called glacial acetic acid.

use
Application: Mainly used for synthesis of vinyl acetate, acetate fiber, acetic anhydride, acetate, metal acetate and halogenated acetic acid. It is also an important raw material for pharmaceutical, dye, pesticide and other organic synthesis. In addition, it is also widely used in the manufacturing of photographic drugs, cellulose acetate, textile printing and dyeing and rubber industries, solvents for the manufacture of plastics, dyes, photography, medicine, pesticides and other raw materials for organic synthesis.
