Product Description
Acetic acid or glacial acetic acid, also known as ethanoic acid, is an organic compound with the chemical formula CH3COOH. Pure glacial acetic acid (anhydrous acetic acid) is a colorless, hygroscopic liquid with a strong pungent odor. The freezing point is 16.6°C, and it turns into colorless crystals after solidification. Ethanoic acid is an organic monobasic acid and can be miscible with water in any proportion. The aqueous solution is weakly acidic and highly corrosive. It is particularly corrosive to metals.
Acetic acid is widely found in nature, such as in the fermentation metabolism and putrefaction products of various glacial acetic acid bacteria. It is also the main component of vinegar. Moreover, glacial acetic acid always plays an important role in many chemical reactions. For example, it can undergo displacement reactions with metals such as iron, zinc, and copper to generate metal acetates and hydrogen. In addition, it can react with alkalis, alkaline oxides, salts and certain metal oxides.

Main Uses of Glacial 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. It is also an important raw material for pharmaceuticals, dyes, pesticides and other organic synthesis.
In addition, glacial acetic acid 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, glacial acetic acid 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.
