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.

Acetic acid (also called acetic acid, glacial acetic acid, or the formula CH COOH) is an organic mono acid that ₃ is the source of the acidity and pungent odor in vinegar. Pure anhydrous acetic acid (glacial acetic acid) is a colorless hygroscopic liquid with a freezing point of 16.7 ° C (62 ° F) and becomes a colorless crystal upon solidification. Although acetic acid is a weak acid based on its ability to dissociate in aqueous solutions, acetic acid is corrosive and its vapors are irritating to the eyes and nose.
