Acetic Acid Glacial extra pure
Description
Acetic Acid Glacial extra pure is a high-purity grade of acetic acid commonly used in laboratories, industrial production, and specialized chemical applications, characterized by a minimum purity of 99.5% and a clear, colorless appearance with a strong vinegar-like odor.
Chemical Properties
Molecular Formula: CH₃COOH.
Purity: Minimum 99.5% (extra pure grade; some variants up to 99.85%).
Physical Appearance: Clear, colorless liquid.
Density: 1.047 - 1.052 g/mL at 20°C.
Boiling Point: 118.1°C.
Melting/Freezing Point: 15.5–16.6°C (crystallizes at room temperature).
Solubility: Miscible with water, alcohol, and various organic solvents.
Non-volatile matter: Less than 0.01%.
Impurities: Chloride, sulfate, arsenic, lead—each present as trace (max. 0.0005% or lower).
Corrosivity: Corrosive to metals and tissue, flammable.
Uses and Applications
Laboratory Reagent: Used as a solvent, pH adjuster, and reagent in analytical and research labs.
Industrial Production: Essential raw material for acetate esters, cellulose acetate (films/textiles), vinyl acetate, pharmaceuticals (aspirin, APIs), and synthetic fibers.
Cleaning Agent: Used to clean and descale surfaces, especially in metalworking and manufacturing.
Food and Beverage: Acts as a preservative, acidity regulator, and antimicrobial agent (diluted forms only; not all extra pure grades are food-safe).
Cosmetics and Pharmaceuticals: Ingredient in various products due to its antimicrobial and acidifying properties.
Agriculture: Listed as a soil pH regulator and herbicide component under certain use cases.
Other: Applied in dyes, rubber, and leather industries for chemical synthesis and processing.
Safety and Handling
Glacial acetic acid is highly concentrated and must be handled with care: it is corrosive to skin, eyes, and mucous membranes, and its vapors can be hazardous if inhaled.
Proper ventilation, personal protective equipment, and strict storage protocols are recommended for laboratory and industrial use.
