55 Gallon Drum - Acetic acid, is a colorless liquid organic compound When undiluted, acetic acid is sometimes called glacial acetic acid vinegar is roughly 3–9% acetic acid by volume, making acetic acid the main component of vinegar apart from water.
Acetic acid has a distinctive sour taste and pungent smell. In addition to household vinegar, it is mainly produced as a precursor to polyvinyl acetate and cellulose acetate. It is classified as a weak acid since it only partially dissociates in solution, but concentrated acetic acid is corrosive and can attack the skin.
Acetic acid is the second simplest carboxylic acid (after formic acid). It consists of a methyl group attached to a carboxyl group. It is an important chemical regent and industrial chemical, used primarily in the production of cellulose acetate for photographic film polyvinyl acetate for wood glue, and synthetic fibers and fabrics. In households, diluted acetic acid is often used in descaling agent. In the food industry, acetic acid is controlled by the food additives code E260 as an acidity regulator and as a condiment.
As a food additive it is approved for usage in many In biochemistry, the acetyl group, derived from acetic acid, is fundamental to all forms of life. When bound to coenzyme A, it is central to the metabolism of carbohydrates and fats.
