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

Glacial acetic acid, also called glacial acetic acid, acetic acid or acetic acid, is an organic compound, chemical formula CH3COOH, is an organic monic acid, the main component of vinegar. Pure anhydrous acetic acid (glacial acetic acid) is a colorless hygroscopic liquid with a freezing point of 16.6 ° C (62 ° F). After solidification, it becomes a colorless crystal, which is weakly acidic and corrosive in its aqueous solution. It is strongly corrosive to metals, and the steam is irritating to the eyes and nose. Acetic acid is widely distributed in nature, such as in fruits or vegetable oils, mainly in the form of esters. Acetic acid is present as free acid in animal tissues, excreta and blood. Many microorganisms can convert different organic matter into acetic acid by fermentation.
