Acetic
acid, systematically named ethanoic acid, is an organic compound
with the chemical formula CH3COOH (also written as CH3CO2H or
C2H4O2). It is a colourless liquid that when undiluted is also
called glacial acetic acid.
The
global demand for acetic acid is around 6.5 million metric tons 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 and subsequent oxidation of
ethanol.
Application: 1. As
one of most important organic raw materials, it is mainly used in
such products as Vinyl acetate, acetic anhydride, diketene, acetate
ester, acetate, acetate fiber and chloroactic acid
etc. 2. It is
an important raw material for synthesized fiber, gooey, medicines,
pesticides and dyes, and also a good organic
solvent. 3.It is
widely applied in such industries as of plastics, rubbers and
printing etc. 4.
Manufacture of acetic anhydride, vinyl acetate; Widely
usedinsolvents, dyes, celluloseacetate, pharmaceuticals,
in-socticides, textile printing.
