Industrially, Acetic Acid Has Been Prepared By Air Oxidation Of Acetaldehyde, Ethanol (Ethyl Alcohol), And Butane And Butene
Acetic Acid |
Acetic Acid is a colourless
liquid chemical compound. Ethanoic Acid is another name for acetic Acid.
Methanol carbonylation produces it. Acetic Acid is widely used as a key
intermediate in the production of chemical products such as Purified
Terephthalic Acid (PTA), Vinyl Acetate Monomer (VAM), and others. Acetic Acid
is widely used in the pharmaceutical, rubber, plastics, construction, and
paints and coatings industries. Polyvinyl acetate is widely used in a variety
of applications, including packaging films, thickeners, and photosensitive
coatings. Polyvinyl alcohol is widely used in paints and paper coatings due to
its excellent adhesion properties.
Acetic Acid, also known as ethanoic
Acid, is an Acidic, colourless liquid and organic compound with the chemical
formula CH3COOH (also written as CH3CO2H, C2H4O2, or HC2H3O2). Vinegar contains
at least 4% acetic Acid by volume, making it the main component of vinegar
other than water and trace elements. Acetic Acid is the second simplest
carboxylic Acid (after formic Acid), with the methyl functional group. It is a
critical chemical reagent and industrial chemical, primarily used in the
manufacture of cellulose acetate for photographic film, polyvinyl acetate for
wood glue, and synthetic fibres and fabrics. Diluted acetic Acid is commonly
used in household descaling agents.
Acetic
Acid is regulated in the food industry under the food additive
code E260 as an Acidity regulator and as a condiment. The acetyl group, derived
from acetic Acid, is essential to all forms of life in biochemistry. It is
essential for carbohydrate and fat metabolism when bound to coenzyme A. The
global demand for acetic Acid is approximately 6.5 million metric tonnes per
year (t/a), with recycling accounting for approximately 1.5 t/a and methanol
accounting for the remainder. Vinegar is mostly dilute acetic Acid, which is
often produced through fermentation and subsequent ethanol oxidation.
The IUPAC name that is most
commonly used and preferred is "acetic Acid." The systematic name
"ethanoic Acid," a valid IUPAC name, is built using substitutive
nomenclature. The term "acetic Acid" is derived from the Latin word
for vinegar, "acetum," and is related to the word "Acid." The
term "glacial acetic Acid" refers to water-free (anhydrous) acetic Acid.
The name comes from the ice-like crystals that form slightly below room
temperature at 16.6 °C (61.9 °F) (the presence of 0.1% water lowers its melting
point by 0.2 °C). It is similar to the German name "Eisessig"
("ice vinegar").
