Etansyra

Etansyra, also known as acetic acid, is a simple carboxylic acid with the chemical formula CH3COOH. It is a colorless liquid that has a distinct pungent and sour smell. Etansyra is the main component of vinegar, which is typically a 3-5% solution of acetic acid in water. In its pure, undiluted form, it is called glacial acetic acid.

This organic compound is produced industrially through various methods, including the carbonylation of methanol. It plays a crucial role in many biological processes, such as the metabolism of carbohydrates. In the chemical industry, etansyra is a vital reagent and precursor for the production of various substances, including vinyl acetate monomer (used in paints and adhesives), cellulose acetate (used in photographic film and textiles), and acetic anhydride.

Beyond industrial applications, etansyra has some household uses, primarily as a cleaning agent due to its acidic properties. It can also be used in food preservation. The characteristic taste and smell of vinegar are directly attributable to the presence of etansyra. In the human body, it is produced by the metabolism of ethanol and is a component of acetyl-CoA, a key molecule in cellular respiration.
