Colorless organic acid glacial acetic acid is one of the important organic acids, organic compounds. It freezes into ice at low temperatures, and the volume expansion upon freezing may cause the container to rupture. The flash point is 39°C, the explosion limit is 4.0% to 16.0%, and the allowable concentration in the air does not exceed 25mg/m3. Pure acetic acid freezes into ice crystals below the melting point, so anhydrous acetic acid is also called glacial acetic acid.

It is a weak acid among organic acids and is widely used in the printing and dyeing industry. Colorless organic acid glacial acetic acid is a colorless liquid, with a concentration of 98%-100% forming ice at a temperature of 16°C, also known as anhydrous acetic acid and anhydrous acetic acid, with a melting point of 16.7°C and a boiling point of 188°C. Most of the products sold in the market have a content of 30%. The concentration of such chemical reagents (analytical pure) sold in chemical stores is more than 98%. The content of edible white vinegar is about 5%, and the edible vinegar essence is about 30%.

This product has a strong irritating sour taste, is corrosive, and has stinging and burning effects on the skin. Colorless organic acid glacial acetic acid can neutralize with alkalis (such as soda ash and caustic soda) to form acetate (sodium acetate) ) and water; it can be esterified with alcohols (such as ethanol) to form ethyl acetate, which is easily soluble in water and has a milder nature.
