acetic acid
It is an organic monobasic acid with the chemical formula of CH3COOH, which is the main component of vinegar. Acetic acid is also called glacial acetic acid and glacial acetic acid. Pure anhydrous acetic acid (glacial acetic acid) is a colorless hygroscopic solid with a freezing point of 16.6℃(62F). After solidification, it is colorless crystal. Its aqueous solution is weakly acidic and corrosive, and steam is irritating to eyes and nose.
Acetic acid is widely distributed in nature, such as fruits or vegetable oils, but mainly exists in the form of esters. It exists in animal tissues, excreta and blood in the form of free acid. Many microorganisms can convert different organic substances into acetic acid by fermentation. Acetic acid is the main component of vinegar, which almost runs through the whole history of human civilization.
Acetic acid fermenting bacteria (Acetobacter) can be found in every corner of the world. Every nation will inevitably find vinegar when making wine-it is the natural product of these alcoholic drinks exposed to the air. In China, for example, there is a saying that Heita, the son of Du Kang, was jealous because he had been brewing for too long.
