Property:
Pure acetic acid is a colorless liquid and has a pungent taste. The melting point is 16.6℃, the boiling point is 117.9℃, and the relative density is 1.049(20/4℃). Soluble in water, ethanol, glycerin, ether Chemicalbook and carbon tetrachloride; Insoluble in carbon disulfide. Anhydrous acetic acid solidifies into ice form at low temperature, commonly known as glacial acetic acid. It is corrosive. It is a weak organic acid with acid commonness and can be esterified with alcohols.
Usage:
1, acetic acid derivatives: mainly used in the synthesis of acetic anhydride, acetate, terephthalic acid, vinyl acetate, polyvinyl alcohol, cellulose acetate, ketenone, chloroacetic acid, halogenated acetic acid, etc.
2, Medicine: acetic acid as a solvent and pharmaceutical raw materials, mainly used in the production of penicillin G potassium, penicillin G sodium, procaine penicillin, antipyretic tablets, sulfadiazine, sulfamethoxazole, norfloxacin, ciprofloxacin, acetylsalicylic acid, phenacetin, prednisone, caffeine, etc.
3, a variety of intermediates: acetate, sodium diacetate, peracetic acid, etc.
4, pigment and textile printing and dyeing: mainly used in the production of disperse dyes and VAT dyes, as well as textile printing and dyeing processing.
5, synthetic ammonia: in the form of copper acetic acid ammonia liquid, used as a synthesis gas refining, to remove a small amount of CO and CO₂ contained in it.
6, in photos: as a developer formula.
7, in natural rubber: used as a coagulant.
8, used as an anticoagulant in the construction industry.
9, in addition, it is also widely used in water treatment, synthetic fibers, pesticides, plastics, leather, paint metal processing and rubber industry.
