Acetic acid glacial is a colorless, hygroscopic liquid with a pungent vinegar-like odor. It is the anhydrous, concentrated form of acetic acid, commonly used as a solvent, reagent, and acidulant in laboratory and pharmaceutical applications.
🏭⚗️ Production
Acetic acid glacial is produced industrially by methanol carbonylation or bacterial fermentation, followed by purification and removal of water to achieve a concentration above 99%.
🔬 Properties
Its chemical formula is CH₃COOH with a molar mass of 60.05 g/mol. The glacial form is a clear, colorless liquid that freezes just below room temperature (~16.7°C). It is miscible with water, alcohols, and many organic solvents. It is a weak acid but highly corrosive in concentrated form.
🧪 Applications
Acetic acid glacial is widely used as a solvent, in the synthesis of pharmaceuticals and chemicals, as a pH adjuster, and as a reagent in organic synthesis. It also serves as a preservative and flavoring agent in the food industry.
⚠️ Safety
Acetic acid glacial is corrosive and can cause severe burns on contact with skin or eyes. Inhalation of vapors may irritate the respiratory tract. Proper personal protective equipment such as gloves, goggles, and lab coats should be used. It should be stored in tightly sealed containers in a cool, well-ventilated area away from oxidizing agents and bases.
