Acetic acid, also known as glacial acetic acid, is an organic compound with the chemical formula CH3COOH. It is an organic monobasic acid and is also the main component of vinegar. Glacial acetic acid is a colorless transparent liquid with a freezing point of 16.6°C. It turns into colorless crystals after solidification. Its aqueous solution is weakly acidic and highly corrosive. It is strongly corrosive to metals. The steam is irritating to the eyes and nose.
The acetic acid is widely distributed in nature. For example, in fruits or vegetable oils, but mainly exists in the form of esters. In animal tissues, excreta and blood, acetic acid exists in the form of free acid. In addition, many microorganisms can ferment different organic compounds into acetic acid.

Main Uses of Acetic Acid 99%
1) Industrial applications
As one of the important organic acids, acetic acid is mainly used in the synthesis of vinyl acetate, cellulose acetate, acetic anhydride, acetate, metal acetate and halogenated acetic acid.
Glacial acetic acid is also an important raw material for pharmaceuticals, dyes, pesticides and other organic synthesis.
In addition, it is also widely used in the manufacture of photographic medicines, cellulose acetate, fabric printing and dyeing, and the rubber industry.
2) Food applications
In the food industry, acetic acid is generally used as an acidulant, flavor enhancer and spice manufacturing.
Synthetic vinegar. Dilute acetic acid to 4-5% with water, add various flavoring agents, the flavor is similar to alcohol vinegar, the production time is short, and the price is cheap.
As a sour agent, it can be used in compound seasonings, prepared vinegar, canned food, jelly and cheese, and used in moderation according to production needs. It can also be used as a flavor enhancer, and the recommended dosage is 0.1-0.3 g/kg.
