Acetic acid

Aceticacid, also known as ethylic acid, glacial acetic acid, is an organic monobasicacid that is a source of sourness and pungent odor in vinegar and the chemicalformula is CH3COOH. Pure anhydrous acetic acid (glacial acetic acid) is acolorless, hygroscopic solid with a freezing point of 16.7 ° C (62 ° F) and solidified as a colorlesscrystal. Although it is a weak acid depending on the dissociation ability ofacetic acid in an aqueous solution, acetic acid is corrosive and its vapor isirritating to the eyes and nose.

Aceticacid is a simple carboxylic acid consisting of a methyl group and a carboxylgroup and is an important chemical reagent. In the chemical industry, it isused to make polyethylene terephthalate that is the main part of beveragebottles. Acetic acid is also used in the manufacture of vinyl acetate forpolyvinyl acetate and wood adhesives for film film, as well as many syntheticfibers and fabrics. In the home, dilute acetic acid solutions are often used asdescaling agents.

Aceticacid is a colorless liquid with a strong pungent sour taste at normaltemperature. The melting point of acetic acid was 16.6 ° C (289.6 K). Theboiling point is 117.9 ° C (391.2 K). The relative density is 1.05, the flashpoint is 39 ° C, and the explosion limit is 4% to 17% (volume). Pure aceticacid freezes into ice crystals below the melting point, so anhydrous aceticacid is also known as glacial acetic acid. Acetic acid is readily soluble inwater and ethanol, and its aqueous solution is weakly acidic. Acetate is alsoreadily soluble in water.

Glacialacetic acid is one of the most important organic acids. Mainly used in vinylacetate, acetic anhydride, acetate fiber, acetate and metal acetate, etc. It isalso used as solvent and raw material for pesticides, pharmaceuticals and dyes.It is widely used in photographic drug manufacturing, textile printing andrubber industry. Glacial acetic acid is one of the important organic chemicalraw materials and it plays an important role in the organic chemical industry.Acetic acid is widely used in synthetic fibers, coatings, pharmaceuticals,pesticides, food additives, dyeing and weaving industries, and is an importantpart of the national economy.
