Application:
Glacial acetic acid is one of the simplest carboxylic acids. It is an important chemical reagent and industrial chemical, used in the production of polyethylene terephtanalate mainly used un soft drink bottles; cellulose acetate, mainly for photographic film; and polyvinyl acetate for wood glue, as well as synthetic fibres and fabrics, in households, dilutes 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.
