How is acetic acid (cas no 64 19 7) produced?
Acetic acid is produced through a chemical reaction called methanol carbonylation, which involves the reaction of methanol and carbon monoxide in the presence of a catalyst such as rhodium. This reaction creates acetic acid and various by-products which are separated and purified through distillation processes.
Main Uses of Glacial Acetic Acid (GAA CAS 64-19-7)
Glacial Acetic Acid (GAA) is acetic acid with ≥99% concentration, named for its low-temperature solidification into ice-like crystals. Its applications include:
Industrial Applications
Chemical Production: Synthesis of vinyl acetate (used in paints and adhesives), terephthalic acid (raw material for PET plastics), etc. Approximately 60% of global GAA is consumed in chemical manufacturing.
Textiles: Used as a pH adjuster in textile dyeing to ensure uniform dye adsorption.
Glacial Acetic Acid Used in lab
Preparing buffers (e.g., acetic acid-sodium acetate buffer, pH 4.0–5.5) for biochemical experiments.
Protein precipitation using 3%-5% acetic acid solution.
glacial acetic acid pharmaceutical use
Plantar warts: 80%+ concentration applied for cauterization under professional supervision.
Otitis externa: Diluted to 2%-3% to inhibit fungi and bacteria.
glacial acetic acid uses in food
Food-grade acetic acid solution (E260) is used in pickling and seasonings, with a safe limit of 10g/kg.
