Glacial acetic acid (purity), namely anhydrous acetic acid, organic compounds. It solidifies into ice at low temperature, commonly known as glacial acetic acid. Volume expansion during solidification may lead to vessel rupture. The flash point is 39 C, the explosion limit is 4.0%-16.0%, and the maximum allowable concentration in the air is not more than 25 mg/m3. Pure acetic acid freezes into ice crystals below the melting point, so anhydrous acetic acid is also called glacial acetic acid.

purpose

Acetic acid is one of the most important organic acids. It is mainly used to synthesize vinyl acetate, acetic fiber, acetic anhydride, acetate, metal acetate and halogenated acetic acid. It is also an important raw material for pharmaceuticals, dyes, pesticides and other organic synthesis. In addition, it has also been widely used in photographic medicine manufacturing, cellulose acetate, fabric printing and dyeing, rubber industry, solvent for manufacturing plastics and dyes, photography, medicine, pesticides and other organic synthetic raw materials.

Pure anhydrous acetic acid is called glacial acetic acid, glacial acetic acid solution is actually acetic acid solution, also known as acetic acid solution. In a sense, 'glacial acetic acid solution' does not exist, because water-added glacial acetic acid can not be regarded as glacial acetic acid, but acetic acid solution or acetic acid solution.

But just as people are accustomed to call sugar water, salt water is generally called brine. Therefore, glacial acetic acid solution is also known as glacial acetic acid solution.
