Acetic Acid

asetikasit formul


Acetic acid is an organic compound with the chemical formula CH3CO2H (also written as CH3COOH). It is a colourless liquid that when undiluted is also called glacial acetic acid. Acetic acid is the main component of vinegar (apart from water), and has a distinctive sour taste and pungent smell. It is mainly produced as a precursor to polyvinylacetate and cellulose acetate. Although it is classified as a weak acid, concentrated acetic acid is corrosive, and attacks the skin.

Acetic acid is one of the simplest carboxylic acids.
It is an important chemical reagent and industrial chemical, mainly used in the production of cellulose acetate mainly for photographic film and polyvinyl acetate for wood glue, as well as synthetic fibres and fabrics. In households, diluted acetic acid is often used in descaling agents. In the food industry, acetic acid is used under the food additive code E260 as an acidity regulator and as a condiment. As a food additive it is approved for usage in the EU, USA and Australia and New Zealand.

Acetic acid from vinegar are sour taste and pungent odor. Carboxylic acids is the smallest. Clear and colorless, it is also corrosive properties.
Acetic acid is completely soluble in water. Salt and the acetate ester is called. CH3COOH chemical formula, molecular weight 60.05 g / mole, 1,266 g/cm3 density, melting point 16.5 ° C and the boiling point of 118.1 ° C.
Vinegar contains acetic acid, 4-5% is usually used to establish a pickle nits, but this proportion reaches 18%. Most foods will cause the acidic environment created by vinegar inhibits the growth of microorganisms. Therefore, an effective method to extend the life of vegetables to make pickles.

The global demand of acetic acid is around 6.5 million tonnes per year (Mt/a), of which approximately 1.5 Mt/a is met by recycling; the remainder is manufactured from petrochemical feedstock. As a chemical reagent, biological sources of acetic acid are of interest but generally uncompetitive. Vinegar is dilute acetic acid, often produced by fermentation.
