Construction
Prevent concrete from freezing. In addition, it is widely used in water treatment, synthetic fibers, pesticides, plastics, leather, paint, metal processing and rubber industriesAcetic acid (also called acetic acid or glacial acetic acid) ₃ is an organic monic acid due to the sourness 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). Upon solidification, it becomes a colorless crystal. 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.

Acetic acid at room temperature is a colorless liquid with strong pungent acid taste. The melting point of acetic acid is 16.6℃ (289.6 K). Boiling point 117.9℃ (391.2 K). The relative density is 1.05, the flash point is 39℃, and the explosion limit is 4% ~ 17% (volume). Pure acetic acid will freeze into ice crystals below the melting point, so anhydrous acetic acid is also called glacial acetic acid. Acetic acid is soluble in water and ethanol, and its aqueous solution is weakly acidic. Acetate is also easily soluble in water, and the aqueous solution is basic.
