Acetic acid is the most commonly used and preferred IUPAC name. The systematic name ethanoic acid, a validIUPAC name, is constructed according to the substitutive nomenclature. The name acetic acid derives from acetum, the Latin word for vinegar, and is related to the word acid itself.
Glacial acetic acid is a name for water-free (anhydrous) acetic acid. Similar to the German name Eisessig (ice-vinegar), 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).

Application:-
Acetic acid is a chemical reagent for the production of chemical compounds. The largest single use of acetic acid is in the production of vinyl acetate monomer, closely followed by and ester production. The volume of acetic acid used in vinegar is comparatively small.
The major use of acetic acid is for the production of vinyl acetate monomer (VAM). In 2008, this application was estimated to consume one third of the world's production of acetic acid.The reaction is of ethylene and acetic acid with oxygen over a palladium catalyst, conducted in the gas phase.
2 H3C-COOH + 2 C2H4 + O2 → 2 H3C-CO-O-CH=CH2 + 2 H2O
Vinyl acetate can be polymerized to polyvinyl acetate or to other polymers, which are components in paints and adhesives.
Diluted acetic acid is used in physical therapy using iontophoresis.
Vinegar is typically 4-18% acetic acid by mass. Vinegar is used directly as a condiment, and in the pickling of vegetables and other foods. Table vinegar tends to be more diluted (4% to 8% acetic acid), while commercial food pickling employs solutions that are more concentrated.
The amount of acetic acid used as vinegar on a worldwide scale is not large, but is by far the oldest and best-known application.
