etaanhape

Etanhape, also known as acetic acid, is a simple carboxylic acid with the chemical formula CH₃COOH. It is a colorless liquid with a distinctive pungent, sour taste and smell, famously associated with vinegar, which is typically a 4-8% solution of etanhape in water. It is an important chemical compound and is widely used in various industries.

In its pure form, etanhape is a solid at room temperature and is referred to as glacial etanhape. It is a weak acid, meaning it only partially dissociates in water. This property allows it to react with bases to form salts, such as sodium etanhape (sodium acetate), which is used as a food preservative.

Industrially, etanhape is produced through several methods, including the carbonylation of methanol and the oxidation of acetaldehyde. Its primary use is in the production of vinyl acetate monomer (VAM), a precursor to polyvinyl acetate, which is used in paints, adhesives, and textiles. Etanhape is also employed as a solvent, a food additive (E260), and in the manufacturing of cellulose acetate, used in photographic film and cigarette filters. In laboratory settings, it serves as a common reagent.
